 55: MPLS L2VPN C

ONFIGURATION

Perform the following tasks to configure the MPLS L2VPN in Kompella mode on a 
PE:

■

Configure interface

■

Enable MPLS and MPLS L2VPN. 

■

Configure BGP parameter

■

Create and configure VPN

■

Create CE and configure CE connection

The first two steps are identical with those for CCC mode, but you should 
configure in advance some reserved interfaces for future expansion. 

The Kompella mode uses BGP as the signaling protocol to allocate VC labels, so 
you should configure BGP parameters on PE. For detailed configuration of BGP 
parameters, refer to Chapter 42 “BGP Configuration”. 

When BGP configuration is completed, you can activate the parameters for the 
peer group in MPLS L2VPN address family view with the following commands: 

Perform the following in the BGP View. 

When the 

command is executed, the system returns to BGP view and delete 

the L2VPN address family. 

Perform the following in the L2VPN View. 

By default, only the peer of BGP IPv4 unicast address family is activated, the peer 
of other types is inactive and cannot exchange routing information.
