Configuring MP-EBGP Between ASBRs in Different ASs

After the MP-EBGP peer relationship is established between ASBRs, an ASBR can advertise the VPNv6 routes of its AS to the other ASBR.

Context

In inter-AS IPv6 VPN Option B, you need not create VPN instances on ASBRs. The ASBR does not filter the VPNv6 routes received from the PE in the same AS based on VPN targets. Instead, it advertises the received routes to the peer ASBR through MP-EBGP.
