This document specifies procedures that allow an EVPN overlay to be fully and automatically provisioned when using RIFT as underlay by leveraging RIFT's no-touch ZTP architecture.
Introduction
RIFT is a protocol that focuses heavily on operational simplicity. [RIFT] natively supports Zero Touch Provisioning (ZTP) functionality that allows each node in an underlay network to automatically derive its place in the topology and configure itself accordingly when properly cabled. RIFT can also disseminate Key-Value information contained in Key-Value Topology Information Elements (KV-TIEs). These KV-TIEs can contain any information and therefore be used for any purpose. Leveraging RIFT to provision EVPN overlays without any need for configuration and leveraging KV capabilities to easily validate correct operation of such overlay without a single point of failure would provide significant benefit to operators in terms of simplicity and robustness of such a solution.
Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
Design Considerations
EVPN supports various service models, this document defines a method for the VLAN-Aware service model defined in [RFC7432]. Other service models may be considered in future revisions of this document.
Each model has its own set of requirements for deployment. For example, a functional BGP overlay is necessary to exchange EVPN NLRI regardless of the service model. Furthermore, the requirements are made up of individual variables, such as each node's loopback address and AS number for the BGP session. Some of these variables may be coordinated across each node in a network, but are ultimately locally significant (e.g. route distinguishers). Similarly, calculation of some variables will be local only to each device. RIFT contains currently enough topology information in each node to calculate all those necessary variables automatically.
Once the EVPN overlay is configured and becomes operational, RIFT Key-Value TIEs can be used to distribute state information to allow for validation of basic operational correctness without the need for further tooling.
Auto-EVPN Device Roles
Auto-EVPN requires that each node understand its given role within the scope of the EVPN implementation so each node derives the necessary variables and provides the necessary overlay configuration. For example, a leaf node performing VXLAN gateway functions does not need to derive its own Cluster ID or learn one from the Route Reflector that it peers with.
All Participating Nodes
Not all nodes have to participate in Auto-EVPN, however if a node does assume an Auto-EVPN role, it MUST derive the following variables:
- IPv6 Loopback Address
Unique IPv6 loopback address used in BGP sessions.
Router ID
The BGP Router ID.
Autonomous System Number
The ASN for IBGP sessions.
Cluster ID
The Cluster ID for Top-of-Fabric IBGP route reflection.
ToF Nodes as Route Reflectors
This section defines an Auto-EVPN role whereby some Top-of-Fabric nodes act as Route Reflectors. It is expected that Route Reflectors would establish IBGP sessions with leaf nodes in the same fabric. The typical Route Reflector requirements do not change, however determining which specific values to use requires further consideration.
ToF nodes performing Route Reflector functionality MUST derive the following variables:
- IPv6 RR Loopback Address
The source address for IBGP sessions with leaf nodes in case ToF won election for one of the Route Reflectors in the fabric.
IPv6 RR Acceptable Prefix Range
Range of addresses acceptable by the Route Reflector to form a IBGP session. This range covers ALL possible IPv6 Loopback Addresses derived by other Auto EVPN nodes in the current fabric and other Auto-EVPN RRs addresses.
Cluster ID
The Cluster ID for Top-of-Fabric IBGP route reflection.
Data Center Interconnect Gateway Functions
Implementations that require connectivity beyond the EVPN/VXLAN boundary can leverage Data Center Interconnect Gateway functionality. This requires additional considerations to ensure the appropriate reachability is present.
First - new VRFs and accompanying variable derivation is required, this is decribed below.
Second - additional Route Reflector election considerations in order to ensure that Route Reflectors with DCI gateway functionality are preferred. This is described later in the document in Section 4.6.2.
If DCI functionality is desired, the Top-of-Fabric nodes MUST be capable of routing toward the correct leaf node when it receives traffic from an external destination. Therefore, it MUST be capable of deriving the following types of variables:
- Route Distinguisher
The route distinguisher corresponding to a IP-VRF's IP prefix routes that MUST uniquely identify each node.
Route Target
The route target that corresponds to an IP-VRF's IP prefix routes.
VNI
The VNI that corresponds to the Type-5 IP prefix routes within an IP-VRF.
Leaf Nodes
Leaf nodes derive their role from realizing they are at the bottom of the fabric, i.e. not having any southbound adjacencies. Alternately, a node can assume a leaf node if it has only southbound adjacencies to nodes with explicit LEAF_LEVEL to allow for scenarios where RIFT leaves do NOT participate in Auto-EVPN.
Leaf nodes MUST derive the following variables:
- IPv6 RR Loopback Addresses
Addresses of the RRs present in the fabric. Those addresses are used to build BGP sessions to the RR.
EVIs
Leaf node derives all the necessary variables to instantiate EVIs with layer-2 and optionally layer-3 functionality.
If a leaf node is required to perform layer-2 VXLAN gateway functions, it MUST be capable of deriving the following types of variables:
- Route Distinguisher
The route distinguisher corresponding to a MAC-VRF that uniquely identifies each node.
Route Target
The route target that corresponds to an EVI.
MAC VRF Name
This is an optional variable to provide a common MAC VRF name across all leaves.
Set of VLANs
Those are VLANs provisioned either within the fabric or allowing to stretch across fabrics.
For each VLAN derived in an EVI the following variables MUST be derived:
- VLAN
The VLAN ID.
Name
This is an optional variable to provide a common VLAN name across all leaves.
VNI
The VNI that corresponds to the VLAN ID. This will contribute to the EVPN Type-2 route.
IRB
Optional variables of the IRB for the VLAN if the leaf performs layer-3 gateway function.
Auto-EVPN Variable Derivation
As previously mentioned, not all nodes are required to derive all variables in a given network (e.g. a transit spine node may not need to derive any or participate in Auto-EVPN). Additionally, all derived variables are derived from RIFT's FSM or ZTP mechanism so no additional flooding beside RIFT flooding is necessary for the functionality.
It is also important to mention that all variable derivation is in some way based on combinations of System ID, EVI ID, Fabric ID, EVI, and VLAN and MUST comply precisely with calculation methods specified in the Auto-EVPN Variable Derivation section to allow interoperability between different implementations. All foundational code elements are also mentioned there.
RIFT System ID
The 64-bit RIFT System ID that uniquely identifies a node as defined in RIFT.
Auto-EVPN Version
This section describes extensions to both the RIFT LIE and Node-TIE packet schemas in the form of a 16-bit value that identifies the Auto-EVPN Version. Auto-EVPN capable nodes MUST support this extension, but MAY choose not to advertise it in LIEs and Node-TIEs when Auto-EVPN is not being utilized.
The complete encoding.thrift schema documented in RIFT describes both major and minor protocol/schema versions. Auto-EVPN Version calculation is done by multiiplying a static value of 256 by the major version then adding the minor version, that is to say - 256 * MAJOR + MINOR.
This section also describes an extension to the NodeCapabilities schema indicating whether or not a node supports Auto-EVPN.
The appendix details described changes to the RIFT LIEPacket, NodeTIEElement, and NodeCapabilities Thrift schemas.
RIFT Fabric ID
RIFT operates on variants of Clos substrate which are commonly called an IP Fabric. Since EVPN VLANs can be either contained within one fabric or span them, Auto-EVPN introduces the concept of a Fabric ID into RIFT.
This section describes extensions to both the RIFT LIE and Node-TIE packet schemas in the form of a 16-bit Fabric ID that identifies a node's membership within a particular fabric. Auto-EVPN capable nodes MUST support this extension but MAY not advertise it when not participating in Auto-EVPN. A non-present Fabric ID and value of 0 is reserved as ANY_FABRIC and MUST NOT be used for any other purpose.
The appendix details necessary changes to the RIFT LIEPacket and NodeTIEElement Thrift schemas.
Auto-EVPN Model
This section describes extensions to the RIFT Node-TIE packet schema that describe a particular EVPN model (e.g. VLAN-Aware).
The appendix details necessary changes to the RIFT NodeTIEElement Thrift schema.
EVI ID
This section describes a variable EVI ID that uniquely identifies an EVPN Instance (EVI) and is used in variable derivation procedures. Each EVPN EVI MUST be associated with a unique EVI ID, this document does not specify a method for making that association or ensuring that they are coordinated properly across fabric(s).
Loopback Address
First and foremost, RIFT does not advertise anything more specific than the fabric default route in the southbound direction by default. However, Auto-EVPN nodes MUST advertise specific loopback addresses southbound to all other Auto-EVPN nodes so to establish MP-BGP reachability correctly in all scenarios.
Auto-EVPN nodes MUST derive a ULA-scoped IPv6 loopback address to be used as both the IBGP source address, as well as the VTEP source when VXLAN gateways are required. Calculation is done using the 6-bytes of reserved ULA space, the 2-byte Fabric ID, and the node's 8-byte System ID. Derivation of the System ID varies slightly depending upon the node's location/role in the fabric and will be described in subsequent sections.
Leaf Nodes as Gateways
Calculation is done using the 6-bytes of reserved ULA space, the 2-byte Fabric ID, and the node's 8-byte System ID.
In order for leaf nodes to derive IPv6 loopback addresses, algorithms shown in both auto_evpn_fidsidv6loopback and auto_evpn_v6prefixfidsid2loopback are required.
IPv4 addresses MAY be supported, but it should be noted that they have a higher likelihood of collision. The appendix contains the required auto_evpn_fidsid2v4loopback algorithm to support IPv4 loopback derivation.
ToF Nodes as Route Reflectors
ToF nodes acting as Route Reflectors MUST derive their loopback address according to the specific section describing the algorithm. Calculation is done using the 6-bytes of reserved ULA space, the 2-byte Fabric ID, and the 8-byte System ID of each elected Route Reflector.
In order for the ToF nodes to derive IPv6 loopbacks, the algorithms shown in both auto_evpn_fidsidv6loopback and auto_evpn_fidrrpref2rrloopback are required.
In order for the ToF derive the necessary prefix range to facilitate peering requests from any leaf, the algorithm shown in "auto_evpn_fid2fabric_prefixes" is required.
A topology MUST elect at least 1 Top-of-Fabric node as an IBGP Route Reflector, but SHOULD elect 3. The election method varies depending upon whether the fabric is comprised of a single plane or multiple planes or if DCI gateway functionality is desired.
Single Plane Route Reflector Election Procedures
Each ToF performs the election independently based on system IDs of other ToFs in the fabric obtained via southbound reflection. The Route Reflector election procedures are defined as follows:
1. ToF node with the highest System ID.
2. ToF node with the lowest System ID.
3. ToF node with the 2nd highest System ID.
4. etc.
This ordering is necessary to prevent a single node with either the highest or lowest System ID from triggering changes to Route Reflector loopback addresses as it would result in all BGP sessions dropping.
For example, if two nodes, ToF01 and ToF02 with System IDs 002c6af5a281c000 and 002c6bf5788fc000 respectively, ToF02 would be elected due to it having the highest System ID of the ToFs (002c6bf5788fc000). If a ToF determines that it is elected as Route Reflector, it uses the knowledge of its position in the list to derive Route Reflector IPv6 loopback address.
The algorithm shown in "auto_evpn_sids2rrs" is required to accomplish this.
Data Center Interconnect Gateway Variations
It is beneficial for ToF-RRs requiring DCI-GW functions to be preferred over ToF-RRs that do not. As such, the "default_acting_auto_evpn_dci_when_tof" flag described in the NodeFlags schema (Appendix B.1) MUST be factored into election procedures mentioned in the previous section. Essentially, ToFs flagged as requiring DCI-GW functions, will be sorted separately from those that do not. That is to say, that ToFs requiring DCI-GW functions will always be preferred as RRs.
For example, if a fabric contains 4 ToF nodes where 2 require DCI-GW functions and the other 2 do not, the election will take place as follows:
1. ToF node (DCI) with the highest System ID.
2. ToF node (DCI) with the lowest System ID.
3. ToF node (non-DCI) with the 2nd highest System ID.
4. ToF node (non-DCI) with the 2nd lowest System ID.
Multiplane Route Reflector Election Procedures
As mentioned in the main RIFT specification, when an implementation uses multiplane fabrics, inter-ToF rings are recommended in order to facilitate northbound flooding between ToFs in different planes.
If a multiplane implementation is using Auto-EVPN, those inter-Tof rings are REQUIRED to ensure that DCI/RR election works as intended.
Each ToF performs the election independently based on system IDs of other ToFs in the other fabrics obtained from northbound flooding across the inter-ToF rings. The highest System ID from each plane will be considered the Plane ID, which is then factored into the election as follows:
1. The ToF node with the highest Plane ID, DCI bit, System ID
2. The ToF node with the lowest Plane ID, DCI bit, System ID
3. The ToF node with the 2nd highest Plane ID, DCI bit, System ID
4. etc.
This algorithm allows DCI/RRs to be split across planes for improved redundancy.
Autonomous System Number
Nodes in each fabric MUST derive a private autonomous system number based on its Fabric ID so that it is unique across the fabric.
The algorithm shown in auto_evpn_fid2private_AS is required to derive the private ASN.
Router ID
Nodes MUST drive a Router ID that is based on both its System ID and Fabric ID so that it is unique to both.
The algorithm shown in auto_evpn_sidfid2bgpid is required to derive the BGP Router ID.
Cluster ID
Route reflector nodes in each fabric MUST derive a Cluster ID that is based on its Fabric ID so that it is unique across the fabric.
The algorithm shown in auto_evpn_fid2clusterid is required to derive the BGP Cluster ID.
Route Target
Nodes hosting EVPN EVIs MUST derive a route target extended community based on the EVI ID for each EVI so that it is unique across the network. Route targets MUST be of type 0 as per [RFC4360].
For example, if given a EVI ID of 1, the derived route target would be "target:1"
The algorithm shown in auto_evpn_evi2rt is required to derive the Route Target community.
Route Distinguisher
Nodes hosting EVPN EVIs MUST derive a type-0 route distinguisher based on its System ID and Fabric ID so that it is unique per node within a fabric.
The algorithm shown in auto_evpn_sidfid2rd is required to derive the Route Distinguisher.
EVPN MAC-VRF Services
It's obvious that applications utilizing Auto-EVPN overlay services may require a variety of layer-2 and/or layer-3 traffic considerations. Variables supporting these services are also derived based on some combination of EVI ID, Fabric ID, and other constant values. Integrated Routing and Bridging (IRB) gateway address derivation also leverages a set of constant RANDOMSEEDS values that MUST be used to provide additional entropy.
In order to ensure that VLAN ID's don't collide, a single deployment SHOULD NOT exceed 6 fabrics with 7 EVIs where each EVI terminates 30 VLANs. The algorithms shown in auto_evpn_fidevivlansvlans2desc and auto_evpn_vlan_description_table are required to derive VLANs accordingly. An implementation MAY exceed this, but MUST indicate methods to ensure collision-free derivation and describe which VLANs are stretched across fabrics.
Lastly, Table 3 shows example derivation results for the previously mentioned scaling figures.
Untagged Traffic in Multiple Fabrics

The algorithm shown in auto_evpn_fidevividsid2v6subnet is required to derive the IPv6 gateway address.
IPv4 IRB Gateway Address
The derived IPv4 gateway address MUST be from a RFC1918 range, which accounts for the first octet. The next octet MUST a hash of the EVI ID and a constant value of 16 that is calculated using the previously mentioned random seed values. Finally, the remaining 2 octets MUST be 0 and 1 respectively.
The algorithm shown in auto_evpn_v4prefixfidevividsid2v4subnet is required to derive the IPv4 gateway address. It should be noted that there is a higher likelihood of address collisions when deriving IPv4 addresses.
Tagged Traffic in a Single Fabric
This section defines a method to derive unique VLAN, VNI, MAC, and gateway address values for deployments where untagged traffic is contained within a single fabric.
VLAN
Tagged traffic contained to a single fabric MUST derive VLAN tags based on EVI ID and Fabric ID in conjunction with a constant value.

The algorithm shown in auto_evpn_v4prefixfidevividsid2v4subnet is required to derive the IPv4 gateway address. It should be noted that there is a higher likelihood of address collisions when deriving IPv4 addresses.
Traffic Routed to External Destinations

The algorithm shown in auto_evpn_evi2rt is required to derive the Route Target community.
RIFT Requirements
RIFT FSM / LIE Validation Requirements
Existing RIFT FSM adjacency rules MUST consider Auto-EVPN Version and Auto-EVPN Fabric ID values so that nodes that do not support Auto-EVPN can interoperate with those that do. The LIE validation is extended with the following clause and if it is not met, miscabling should be declared:

(if fabric_id is not advertised by either node OR
 if fabric_id is identical on both nodes)
    AND
(if auto_evpn_version is not advertised by either node OR
 if auto_evpn_version is identical on both nodes)

RIFT Node-TIE Advertisements
All nodes utilizing Auto-EVPN MUST advertise their Auto-EVPN Version, Auto-EVPN Fabric ID, and Auto-EVPN Model values in at least one Node-TIE in each direction (i.e. North and South).
Operational Considerations
To fully realize the benefits of Auto-EVPN, it may help to describe the high-level methodology. Simply put, RIFT automatically provisions the underlay and Auto-EVPN provisions the overlay. The goal of this section is to draw clear lines between general fabric concepts, RIFT, and Auto-EVPN and how they fit into current network designs and practices.
This section also describes an set of optional Key-Value TIEs that leverages the variables that have already been derived to provide further operational enhancement to the operator.

Figure 1 illustrates a typical 5-stage Clos IP fabric. Each node is labelled in such a way that conveys the following:
1. The nodes placement within the generic IP fabric.
2. The nodes role within the RIFT IP underlay.
3. The nodes role within the Auto-EVPN overlay.
Table 1 should also help further align these concepts.
Role Associations
Fabric Placement | RIFT Role | Auto-EVPN Role
Superspine | Top-of-Fabric | Route Reflector and/or DCI Gateway
Spine | Spine or Top-of-PoD | N/A
Leaf | Leaf | Leaf Gateway
It's also important to remember that Auto-EVPN simply takes existing EVPN overlay deployment scenarios and simplifies the provisioning. Figure 2 further illustrates the resulting EVPN overlay topology.

Auto-EVPN Analytics
Leaf nodes MAY optionally advertise analytics information about the Auto-EVPN fabric to ToF nodes using RIFT Key-Value TIEs. This may be advantageous in that overlay validation and troubleshooting activities can be performed on the ToF nodes.
Auto-EVPN Analytics (Global) Key/Value Pair
This Key/Value pair describes node level information within the context of the Auto-EVPN fabric. The System ID of the advertising leaf node MUST be used to differentiate the node among other nodes in the fabric.
The Auto-EVPN Analytics (Global) Key/Value pair MUST be advertised with the Auto-EVPN Fabric ID encoded into the Key Identifier according to the function in Figure 31.
