Configuring a remote CCC connection
To configure a remote CCC connection, perform the following configurations on the PE and P devices:
On the two PEs, use the ccc command to specify the incoming and outgoing labels.
On each P device between the two PEs, use the static-lsp transit command to configure a static LSP for each direction of the CCC connection. For more information about the static-lsp transit command, see MPLS Command References.
Follow these guidelines when you configure a remote CCC connection:
The outgoing label specified on a device must be the same as the incoming label specified on the next-hop device.
CCC connection settings such as the encapsulation type and control word function must be consistent on the two PEs. Otherwise, the PEs might fail to forward packets over the CCC connection.
To configure a remote CCC connection:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter cross-connect group view. | xconnect-group group-name | N/A |
3. Enter cross-connect view. | connection connection-name | N/A |
4. Create a remote CCC connection. | ccc in-label in-label-value out-label out-label-value { nexthop nexthop | out-interface interface-type interface-number } [ pw-class class-name ] | By default, no remote CCC connection is created. Use the out-interface keyword to specify the outgoing interface only on a point-to-point link. On other types of interfaces such as Layer 3 Ethernet interface, VLAN interface, and Layer 3 aggregate interface, you must use the nexthop keyword to specify the IP address of the next hop. |
