Abstract:
With BGP/MPLS VPNs any-to-any connectivity among sites of a given
Virtual Private Network would require each Provider Edge router that
has one or more of these sites connected to it to hold all the routes
of that Virtual Private Network. The approach described in this
document allows to reduce the number of Provider Edge routers that
have to maintain all these routes by requiring only a subset of these
routers to maintain all these routes.
Furthermore, when Provider Edge routers use ingress replication to
carry multicast traffic of VPN customers, the approach described in
this document may under certain circumstances allow to reduce
bandwidth inefficiency associated with ingress replication, and to
redistribute the replication load among Provider Edge routers.
