MPLS L2VPN configuration commands
ccc interface in-label out-label
Use ccc interface in-label out-label to create a remote Circuit Cross Connect (CCC) connection between
CEs connected to different PEs.
Use undo ccc to delete a CCC connection.
Syntax

out-label-value { nexthop ip-address | out-interface interface-type interface-number } [ control-word |

Parameters
ccc-connection-name: Specifies the CCC connection name, a case-insensitive string of 1 to 20 characters.
It is used for uniquely identifying a CCC connection on a PE.
interface interface-type interface-number: Specifies the interface connecting the local CE by its type and
number.
in-label in-label-value: Specifies the incoming label in the range of 16 to 1023.
out-label out-label-value: Specifies the outgoing label in the range of 16 to 1023.
nexthop ip-address: Specifies the IP address of the next hop.
out-interface interface-type interface-number: Specifies the outgoing interface by its type and number.
control-word: Enables the control word function.
no-control-word: Disables the control word function.
ip-interworking: Enables the CCC connection to support IP interworking. If you specify this keyword,
when the PE receives a packet from an AC, it extracts the IP packet from the packet, sends the IP packet
to the peer PE over the CCC connection. When the PE receives a packet from the CCC connection, it
encapsulates the IP packet according to the link type of the AC bound to the CCC connection, and sends
the encapsulated packet to the AC link. In this way, the PEs at the two ends of a CCC connection shield
the differences between two AC links, implementing communication between the ACs with different link
types.
Usage guidelines
This command must be configured on both the local and remote PEs of a CCC connection.
A PE uses connection names to identify different CCC connections. A CCC connection can have different
names on different PEs.
