Technical Summary

In "Multicast Virtual Private Networks" (MVPNs), customer 
multicast flows are carried in "tunnels" through a service 
provider's network. The base specifications for MVPN 
define BGP multicast VPN "auto-discovery" routes, and
specify how to use an auto-discovery route to advertise 
the fact that an individual customer multicast flow is 
being carried in a particular tunnel.

However, those specifications do not provide a way 
to specify, in a single such route, that multiple customer 
flows are being carried in a single tunnel. Those 
specifications also do not provide a way to advertise 
that a particular tunnel is to be used by default to 
carry all customer flows, except in the case where
that tunnel is joined by all the provider edge routers 
of the MVPN.

This document eliminates these restrictions by specifying 
the use of "wildcard" elements in the customer flow 
identifiers. With wildcard elements, a single 
auto-discovery route can refer to multiple customer 
flows, or even to all customer flows.
