For more configuration information, see "Configuring MPLS L3VPN."
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 ordinary IBGP peer relationships 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:
Ste
p
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 the IBGP peer.
peer { group-name | ip-address }
as-number as-number
N/A
4. 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 the IPv4
peer/peer group.
5. Configure the PE of another
AS as the EBGP peer.
peer { group-name | ip-address }
as-number as-number
N/A
6. Enter BGP-VPNv6 subaddress
family view.
ipv6-family vpnv6 N/A
7. Enable the PE to exchange
BGP VPNv6 routing
information with the EBGP
peer.
peer ip-address enable N/A
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. For more information, see "Configuring MPLS L3VPN."
Configuring the routing policy
After you configure and apply a routing policy on an ASBR PE, it 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"
