Hi All,

Have below query on BGP CAR draft section  "2.9.2.3 SRv6 SID TLV"

1) why we are using Prefix-SID attribute ?
The idea was omitting BGP Prefix SID Attribute from the color-aware routes for better BGP packing efficiency.

2) Which SID we are advertising in BGP Prefix SID Attribute ?

Thanks
Rajesh

Hi Rajesh,

As specified in the draft-ietf-srv6-services draft, when using transposition scheme prefix SID attribute carries common part of SRv6 SID  (example locator). draft-dskc-bess-bgp-car proposes to carry variable part in SRv6 SID TLV in NLRI when same scheme is used. This helps to be efficient in number of bytes consumed for each NLRI. We will clarify this in draft.

Regards
Swadesh

Hi Swadesh,

This I understood by going through the draft thoroughly. But definitely more clarification is better  as you pointed.

1) So SRv6 SID TLV is used only to carry variable part ? it will never carry complete SID ?

2) Is there any case where we carry a complete SID1 in prefix SID attribute as well as complete SID2 in SRv6 SID TLV ?

Thanks
Rajesh
