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:

Command Remarks
1. Enter system view.
system-view
N/A
2. Enter BGP view.
bgp as-number N/A
3. Configure the ASBR PE in the
same AS as an IBGP peer.
peer { group-name | ip-address }
as-number as-number
By default, no BGP peer is
configured.
4. Enter BGP IPv4 unicast
address family view.
address-family ipv4 [ unicast ] N/A
5. Enable the PE to exchange
BGP IPv4 unicast routes with
the ASBR PE in the same AS.
peer { group-name | ip-address }
enable
By default, the PE does not
exchange BGP IPv4 unicast routes
with any peer.
6. Enable the PE to exchange
labeled routes with the ASBR
PE in the same AS.
peer { group-name | ip-address }
label-route-capability
By default, the PE does not
advertise labeled routes to any
IPv4 peer/peer group.
7. Return to BGP view.
quit N/A
8. Configure the PE of another
AS as the EBGP peer.
peer { group-name | ip-address }
as-number as-number
N/A
9. Enter BGP-VPNv6 address
family view.
address-family vpnv6 N/A
10. Enable the PE to exchange
BGP VPNv6 routing
information with the EBGP
peer.
peer ip-address enable
By default, the PE does not
exchange labeled routes with any
IPv4 peer/peer group.
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 MPLS L3VPN."
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 L3VPN."
