Configuring CCC MPLS L2VPN
Configuring a local CCC connection
To create a local CCC connection on a PE:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Create a local CCC
connection on the PE to
connect two CEs.
ccc ccc-connection-name interface
interface-type interface-number
out-interface interface-type
interface-number
The two interfaces specified in this
command are those connected to
the two CEs.
By specifying the two interfaces,
you bind the AC links to the CCC
connection.
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 of the connection, use the ccc interface in-label out-label command to specify the
incoming and the outgoing labels, and other information as needed. You do not need to configure
two static LSPs (with the static-lsp command) for each remote CCC connection.
• On each P device between the two PEs, use the static-lsp command to configure a static LSP for both
directions of the CCC connection.
Configuring a PE
Follow these guidelines when you configure a remote CCC connection on a PE:
• The label range for CCC is 16 to 1023, which is the label range for 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.
• In CCC mode, if the PE-CE interface of a PE is an Ethernet subinterface, 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.
