Configuring EBGP between an IPv6 MCE and a VPN site
To use EBGP for exchanging routing information between an IPv6 MCE and IPv6 VPN sites, you must
configure a BGP peer for each IPv6 VPN instance on the IPv6 MCE, and redistribute the IGP routes of
each VPN instance on the IPv6 VPN sites.
If EBGP is used for route exchange, you also can configure filtering policies to filter the received routes
and the routes to be advertised.
