It's similar to CCC but with label stacking ( Tunnel/LSP and VC labels )
1- In the core:
- MPLS enable on core interfaces
- LDP enable on core interfaces: to create MPLS LSP ( or RSVP for LDP over RSVP )
- extended LDP session ( targeted-LDP for Alcatel/Nokia ) enable on l0.0 interface
- single-area OSPF / Single IGP domain ( BGP or RVSP not needed )
2- PE Router: extended LDP session
- Neigbor IP@
- outgoing interface
- VC-ID ( same both end!!!)
3- PE Router: VPN service
- interface and logica interface: Layer 2 VPN interfaces
- CCC or TCC encapsulation
3- CE Router
CCC encapsulation: same vlan at both end
TCC encapsulation: different vlan used by CE
