Configuring Inter-As Ipv6 Vpn Option C - HP 12500 Series Configuration Manual

To configure inter-AS IPv6 option A, you need to:
• Perform basic IPv6 MPLS L3VPN configuration on each AS.
Configure each ASBR, taking the peer ASBR PE as its CE. In other words, configure VPN instances
•
on both PEs and ASBR PEs. The VPN instances on PEs allow CEs to access the network, while those
on ASBR PEs are for access of the peer ASBR PEs.
For configuration information, see
NOTE:
In the inter-AS IPv6 VPN option A solution, for the same IPv6 VPN, the VPN targets configured on the PEs
must match those configured on the ASBR-PEs in the same AS to make sure that VPN routes sent by the PEs
(or ASBR-PEs) can be received by the ASBR-PEs (or PEs). VPN targets configured on the PEs in different
ASs do not have such requirements.

Configuring inter-AS IPv6 VPN option C

Configuring the PEs
You need to establish ordinary iBGP peer relationships between PEs and ASBR PEs in an AS and
MP-eBGP peer relationships 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:
To do...
Enter system view
Enter BGP view
Configure the ASBR PE in the same
AS as the iBGP peer
Enable the PE to exchange labeled
routes with the ASBR PE in the
same AS
Configure the PE of another AS as
the eBGP peer
Enter BGP-VPNv6 subaddress
family view
Enable the PE to exchange BGP
VPNv6 routing information with the
eBGP peer
Configuring the ASBR PEs
In the inter-AS IPv6 VPN option C solution, an inter-AS LSP is required, and the routes advertised between
the relevant PEs and ASBRs must carry MPLS label information. The configuration is the same as that in
the Inter-AS IPv4 VPN option C solution (see
Configuring the routing policy
After you configure and apply a routing policy on an ASBR PE, it:
"Configuring basic IPv6 MPLS
Use the command...
system-view
bgp as-number
peer { group-name | ip-address }
as-number as-number
peer { group-name | ip-address }
