 49: BGP/MPLS VPN C

ONFIGURATION

This command adds a default route which uses local address as the next hop on 
the PE SPE (system processing engine)

Perform the following configuration in VPNv4 sub-address family view.

Step 6: Configure BGP neighbor as the User-end PE (UPE) of BGP/MPLS VPN

This command is only used for UPE of BGP/MPLS VPN.

Configure the following commands in the VPNv4 sub-address family view.

P router does not maintain VPN routes, but do keep connection with public 
network and coordinate with PE in creating LSPs. These configurations are 
required on P router:

Step 1: Configure MPLS basic capacity and enable LDP on the interfaces 
connecting P router to PE router, for forwarding MPLS packets. See  “MPLS Basic 
Capability Configuration”.

Step 2: Enable OSPF protocol at the interfaces connecting P router to PE router 
and import direct-connect routes. See "OSPF" part in "Routing Protocol" for 
details.

After the above configuration, execute display command in any view to display 
the running of the VPNv4 information in BGP database configuration, and to verify 
the effect of the configuration.
