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. Configure the PE in another
AS as an EBGP peer.
5. Enter BGP IPv4 unicast
address family view.
6. Enable the PE to exchange
BGP IPv4 unicast routes with
the ASBR-PE in the same AS.
7. Enable the PE to exchange
labeled routes with the
ASBR-PE in the same AS.
8. Return to BGP view.
9. Enter BGP VPNv6 address
family view.
10. 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 needed, and the routes advertised between
the PEs and ASBRs must carry MPLS label information. The configuration is the same as that in the
Inter-AS IPv4 VPN option C solution. For more information, see
Configuring the routing policy
A routing policy on an ASBR-PE does the following:
Assigns MPLS labels to routes received from the PEs in the same AS before advertising them to the
•
peer ASBR-PE.
• Assigns new MPLS labels to the labeled routes to be advertised to the PEs in the same AS.
The configuration is the same as that in the Inter-AS IPv4 VPN option C solution. For more information,
see "Configuring MPLS
