4.6 Configuring a Kompella VLL

This section describes how to configure the Kompella VLL, that is, how to implement VLL on
the MPLS network in end-to-end (CE-to-CE) mode. The Kompella VLL uses BGP to transmit
L2VPN information and VC labels.

Applicable Environment
Kompella VLL uses BGP as the signaling protocol to transmit L2VPN information between
PEs.
Similar to the BGP/MPLS VPN, the Kompella VLL also uses the VPN targets to control the
transceiving of VPN routes, which makes the networking flexible.
The Kompella mode uses the label block. Each CE is allocated with a label block. The size of
the label block decides the number of CEs connected to this CE. Thus, some additional labels
are allocated for the VPN for future extensibility. PEs transmit packets by figuring out the in-
label for transmitting packets according to these label blocks. Kompella thus features better
expansibility. The Kompella VLL supports local connections and remote connections.

Data Preparation
To configure a Kompella VLL, you need the following data.
Issue 03 (2009-08-20)
Configuring the static routes or an IGP protocol on PE and P on the MPLS backbone
network to implement IP connectivity
Configuring basic MPLS functions on PEs and P
Setting up a tunnel, which can be CR-LSP or LSP, tunnel, between PEs according to the
tunnel policy
NOTE
The IGP and LDP protocols are not required for the local connection.
