Configuring Inter-As Ipv6 Vpn Option A; Configuring Inter-As Ipv6 Vpn Option C - HP MSR2000 Configuration Manual

Configure MPLS LDP for the MPLS backbones so that LDP LSPs can be established.
•
The following sections describe inter-AS IPv6 VPN option A and option C. Select one according to your
network scenario.

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:
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 BGP to exchange BGP
IPv4 unicast routes with the
ASBR-PE in the same AS.
6. Enable
labeled
ASBR-PE in the same AS.
7. Return to BGP view.
8. Configure the PE of another AS
as the EBGP peer.
