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 a VLAN interface or 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.
To configure a PE:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Create a remote CCC
connection.
ccc ccc-connection-name interface
interface-type interface-number in-label
in-label-value out-label out-label-value
{ nexthop ip-address | out-interface
interface-type interface-number }
[ control-word | no-control-word ]
[ ip-interworking ]
The interface interface-type
interface-number option specifies
a PE-CE interface of the PE. By
specifying the interface, you bind
the AC link on the interface to the
remote CCC connection to be
created.
Configuring a P device

2. Configure a transit static LSP.

{ nexthop next-hop-addr |
outgoing-interface interface-type
interface-number } out-label out-label

Configuring SVC MPLS L2VPN
You can configure an ordinary static VC (SVC) or configure a pair of primary and backup SVCs in the
following methods:
• Configure a static VC on a Layer 3 interface. This method does not support VC redundancy.
