4.7.2 Configuring Inter-AS IPv6 VPN Option A

This part describes how to configure an IPv6 VPN instance on the PE and ASBR to be
respectively associated with the CE and the peer ASBR.
Context
Inter-AS IPv6 VPN-Option A is easy to deploy. When the amount of the IPv6 VPNs and the
VPN-IPv6 routes on the PE is small, the Option A can be adopted.
The configurations of the inter-AS VPN-Option A are as follows:
Issue 01 (2011-07-15)
Configuring IGP for MPLS backbone networks in each AS to realize IP connectivity of the
backbones in one AS
Enabling MPLS on the PEs and the ASBRs
Setting up the tunnel (LSP or MPLS TE) between the PE and the ASBR in the same AS
Enabling IPv6 on PEs, CEs and on the interfaces that need to be configured with IPv6
Configuring the IPv6 address of the CE interface through which the CE accesses the PE
Data
To configure the IPv6 VPN instance on the PE and the ASBR, you need the following
data:
l Name of the IPv6 VPN instance
l (Optional) Description of the IPv6 VPN instance
l RD, VPN Target
l (Optional) Routing policy that controls the receiving and sending of IPv6 VPN
routes
l (Optional) Tunnel policy
l (Optional) The maximum number of routes allowed by the IPv6 VPN instance
IPv6 addresses of the PE interfaces attached to the CE
AS number of the PE
IPv6 addresses of the interfaces connected the ASBRs
Routing protocol adopted between the PE and the CE: static route, RIPng, IS-ISv6,
or BGP4+
IPv4 addresses and interfaces between the PE and ASBR to establish the MP-IBGP
peers
