Caution:
With LDP/MPLS L2VPN, the VC ID assigned to a link must be unique among all the
links with the same encapsulation type. Any encapsulation change is likely to cause VC
ID collision. Suppose that both the interfaces serial0 encapsulated with HDLC and
serial1 encapsulated with PPP have created the LDP connections, both of which are
assigned with VC ID 1. If the link layer encapsulation type on serial1 is changed to
HDLC, there will be two CCC-HDLC encapsulated LDP connections with the same VC
ID of 1. To avoid the VC ID collision of these two connections, the LDP connection on
serial1 will be automatically deleted.

4.5 Configuration of MPLS L2VPN in Kompella Mode

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.

4.5.1 Configuring BGP Parameters

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 BGP Configuration of Routing Protocol Module.
When BGP configuration is completed, you can activate the parameters for the peer
group in MPLS L2VPN address family view with the following commands:
I. Entering L2VPN address family view
Perform the following configurations in BGP view.
Table 4-12 Enter L2VPN address family view
Enter L2VPN address family view
Exit L2VPN address family view
