4.2.5 Creating CCC Connection

CCC connections fall into local connection and remote connection. Local connection
refers to the connection established between two local CEs. With local connection,
switching can be directly implemented on PE without using static LSP. Remote
connection refers to the connection between a local CE and a remote CE, that is, two
CEs connected to different PEs. In this case, two static LSPs (one in each direction) are
required for PE-PE packet transmission.
Perform the following configurations in system view.

Caution:
A remote CCC connection uses its LSP in an exclusive way.
Therefore, two static LSPs (with each in one direction) must be configured for each
remote CCC connection, rather than having two CCC connections share the same
static LSP. A static LSP that has been used by a remote CCC connection cannot be
used for other purposes like carrying IP or BGP/MPLS VPN data. For this reason, when
creating a static LSP for a CCC connection, you are recommended to assign an IP
address beyond the local network to the FEC of the CCC connection to prevent the
likelihood of selecting the LSP for routing.
For one FR interface, L2 MPLS VPN can only be encapsulated on one subinterface.
Therefore, the following configuration is invalid:
ccc vpntest interface Serial6/0/0.2 out-interface Serial6/0/1.1
ccc vpnfr interface Serial6/0/0.1 transmit-lsp 2to3 receive-lsp 3to2
