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 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 "
Resetting BGP connections
When BGP configuration changes, use the soft reset function or reset BGP connections to make the
changes take effect. Soft reset requires that BGP peers have the route refreshment capability, which
means supporting Route-Refresh messages.
Soft reset of BGP connections refers to updating BGP routing information without breaking BGP neighbor
relationships. Hard reset of BGP connections refers to updating BGP routing information by breaking and
then reestablishing BGP neighbor relationships.
To hard reset or soft reset BGP connections:
