Configuring inter-AS IPv6 VPN option A
Inter-AS IPv6 VPN option A applies to scenarios where the number of VPNs and that of VPN routes
on the PEs are relatively small.
To configure inter-AS IPv6 option A:
•
Configure basic IPv6 MPLS L3VPN on each AS.
•
Configure VPN instances on both PEs and ASBR-PEs. The VPN instances on PEs allow CEs
to access the network, and those on ASBR-PEs are for access of the peer ASBR-PEs.
For more configuration information, see "
."
In the inter-AS IPv6 VPN option A solution, for the same IPv6 VPN, the route targets configured on
the PEs must match those configured on the ASBR-PEs in the same AS. This makes sure VPN
routes sent by the PEs (or ASBR-PEs) can be received by the ASBR-PEs (or PEs). Route targets
configured on the PEs in different ASs do not have such requirements.
Configuring inter-AS IPv6 VPN option C
To configure inter-AS IPv6 VPN option C, perform proper configurations on PEs and ASBR-PEs, and
configure routing policies on the ASBR-PEs.
Configuring the PEs
Establish an IBGP peer relationship between a PE and an ASBR-PE in an AS, and an MP-EBGP
peer relationship between PEs in different ASs.
The PEs and ASBR-PEs in an AS must be able to exchange labeled routes.
To configure a PE for inter-AS IPv6 VPN option C:

6.
Enable the PE to exchange
BGP IPv4 unicast routes with
the ASBR-PE in the same
AS.

By default, the PE does not
exchange BGP IPv4 unicast
routes with any peer.

Enable the PE to exchange
labeled routes with the
ASBR-PE in the same AS.

By default, the PE does not
advertise labeled routes to any
