Configuring EBGP between an MCE and a VPN site
To use EBGP between an MCE and IPv6 VPN sites, you must configure a BGP peer for each IPv6
VPN instance on the MCE, and redistribute the IGP routes of each VPN instance on the IPv6 VPN
sites. You can also configure the filtering of received and advertised routes.
1.
Configure the MCE:
Step
1.
Enter system view.
2.
Enter BGP view.
3.
Enter BGP-VPN instance
view.
4.
Specify an IPv6 BGP peer in
an AS.
5.
Enter BGP-VPN IPv6 unicast
address family view.
6.
Enable BGP to exchange
IPv6 unicast routes with the
specified peer.
7.
Redistribute remote site
routes advertised by the PE.
8.
(Optional.) Configure filtering
of advertised routes.
9.
(Optional.) Configure filtering
of received routes.
2.
