Configuring VLAN encapsulation
When you configure Martini MPLS L2VPN for a service instance, you can specify the encapsulation type
for the PE-CE interface. When you configure MPLS L2VPN other than the Martini mode, you can only use
the default encapsulation type on the PE-CE interface.
By default, a VLAN interface uses VLAN encapsulation (the VLAN interface and the CE must reside in the
same VLAN). For configuration information about VLAN interface, see
Layer 2—LAN Switching

Configuring a remote CCC connection
To configure a remote CCC connection, perform the following configuration on the PE and P devices:
•
On a PE, you do not need to create static LSPs (with the
static-lsp
command) for a remote CCC
connection. Instead, you only need to configure the incoming and outgoing labels by using the
ccc
interface in-label out-label
command on each PE of the remote CCC connection.
•
On each P device between the PEs, you must use the
static-lsp
command to create two static LSPs
in opposite directions to dedicatedly transmit data of the CCC connection.
Follow these guidelines to configure a remote CCC connection:
•
The label range for CCC is 16 to 1023, which is the label range for static LSPs.
•
In CCC mode, if the PE-CE interface of a PE is a VLAN interface, all packets sent from the PE to the
CE carry a VLAN tag. You must configure the PE-CE interface of the CE to permit the packets that
carry that VLAN tag.
To configure a PE:

The

option specifies a
PE-CE interface of the PE. By specifying
the interface, you bind the AC link of
the interface to the remote CCC
connection to be created.

Configuring SVC MPLS L2VPN
SVC MPLS L2VPN does not use any signaling protocol to transfer L2VPN information. It uses tunnels to
transport data between PEs.
