Two types of CCCconnections exist: local CCCconnection and remote CCCconnection. A local CCCconnection is establishedbetween two local CEs. It can beswitched directly by the PEwithout being configured a staticLSP. A remote CCC connectionis established between the localCE and a remote CE. The twoCEs are attached to differentPEs. In this case, you need toconfigure two static LSPs forbidirectional packets transmittedbetween the two PEs.Caution:z In L2VPN, you can configure only one virtual circuit for each VLAN interface.z L2VPN supports VLAN interfaces only. When you configure an L2VPN on a VLANinterface, data is encapsulated as Ethernet packets by default.z You must use cards with the suffix CA (such as LSB2FT48CA) for the access sidesof CCC public/private network.z You can configure only one VLAN on the access side of each VPN private network.Each VLAN can have only one interface, and all the VLANs connecting to theinterface must have IGMP disabled.z You must configure two static LSPs for each remote CCC connection. Two CCCconnections cannot share one static LSP.z A static LSP used by a remote CCC connection cannot be used for other purposes(such as carrying IP packets and BGP/MPLS VPN packets). When you configure astatic LSP for a CCC connection, the next hop must be the IP address from whichthe ARP packets are learnt.4.2.2 CCC MPLS L2VPN Configuration ExampleI. Network requirementsCEs and the corresponding PEs shown in Figure 4-4 are interconnected through theirGigabitEthernet ports. Data is encapsulated as Ethernet packets at the data link layer. Alocal connection is required between CE-A and CE-B, and a remote connectionbetween CE-A and CE-C.
