CAUTION:
•
You do not need to configure two static LSPs for each remote CCC connection. Instead, you must
configure the incoming and outgoing labels, where the incoming label must be exclusively for the CCC
connection. The labels function as static LSPs.
• Only when the link that the outgoing interface connects is a point-to-point link, can you use the
out-interface keyword to specify the outgoing interface. If the link is not a point-to-point link but, for
example, a link connecting to Layer 3 Ethernet interface, VLAN interface, or Layer 3 aggregate
interface, you must use the nexthop keyword to specify the IP address of the next hop.
Configuration on the P devices
Perform the following configuration on a P device:

Required
CAUTION:
•
With CCC, no static LSPs are required on the PEs but dedicated bidirectional static LSPs are required on
all the P devices between the PEs for transmitting the data of the CCC connection.
• For static LSP configuration commands, see MPLS Command Reference.
Configuring SVC MPLS L2VPN
SVC MPLS L2VPN does not use any signaling protocol to transfer L2VPN information. Instead, it uses
tunnels to transport data between PEs.
SVC supports these tunnel types: LDP LSP and CR-LSP. By default, LDP LSP tunnels are used.
Configuration prerequisites
Before you configure SVC MPLS L2VPN, complete the following tasks:
• Configure an IGP on the PEs and P devices to guarantee the IP connectivity of the MPLS backbone.
• Configure basic MPLS and MPLS LDP for the MPLS backbone on the PEs and P devices to establish
LDP LSPs.
• Enable MPLS L2VPN on the PEs.
• Establish the tunnels between PEs according to the tunneling policy.
To configure SVC MPLS L2VPN, you need the following data:
• Types and numbers of the interfaces connecting the CEs
• Destination LSR ID of SVC
• Incoming and outgoing labels of the L2VPN connection
• SVC tunneling policy
