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."
Displaying and maintaining IPv6 MPLS L3VPN
You can use soft-reset or reset BGP connections to apply new BGP configurations. Soft reset requires that
BGP peers have route refresh capability (supporting Route-Refresh messages).
NOTE:
Soft reset of BGP connections updates BGP routing information without breaking BGP neighbor
relationships. Reset of BGP connections updates BGP routing information by breaking and then
reestablishing BGP neighbor relationships.
Use the following commands to reset or soft reset BGP connections:
Task Command Remarks
Soft reset BGP VPNv6 connections.
refresh bgp { ip-address | all | external |
group group-name | internal } { export |
import } vpnv6
Available in user view.
Reset BGP VPNv6 connections.
reset bgp { as-number | ip-address | all |
external | internal | group group-name }
