Configuring Inter-As Ipv6 Vpn Option A; Configuring Inter-As Ipv6 Vpn Option C - HP 10500 Series Configuration Manual

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 to make 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:
Step
1. Enter system view.
2. Enter BGP view.
3. Configure the ASBR PE in the
same AS as an IBGP peer.
4. Enter BGP IPv4 unicast
address family view.
5. Enable the PE to exchange
BGP IPv4 unicast routes with
the ASBR PE in the same AS.
6. Enable the PE to exchange
labeled routes with the ASBR
PE in the same AS.
7. Return to BGP view.
8. Configure the PE of another
AS as the EBGP peer.
