Configuring MPLS basic capability for the MPLS backbone on the PEs and P devices.
z
Enabling MPLS L2VPN on PEs of the MPLS backbone. You do not need to enable MPLS L2VPN
on the P devices.
To configure CCC MPLS L2VPN, you need the following data:
z
Name for the CCC connection
z
Connection type: local or remote
z
For a local CCC connection: the types and numbers of the incoming and outgoing interfaces
z
For a remote CCC connection: the type and number of the incoming interface, the address of the
next hop or the type and number of the outgoing interface, and the incoming and outgoing labels of
the LSRs along the CCC connection
When configuring a remote connection, if the link that the outgoing interface connects is not a
point-to-point link (for example, when the outgoing interface is a VLAN interface), you need to specify
the IP address of the next hop. If not, you need to specify the outgoing interface.
Configuration Procedure

Required
You do not need to configure two static LSPs for each remote CCC connection. Instead, you only need
to configure the incoming and outgoing labels, where the incoming label must be exclusively for the
CCC connection. The labels function as static LSPs.
2) Configure the P devices
