CAUTION: Following must be met to make an LDP Layer 2 VPN to go up:
The interfaces of the two CE are physically up.
■
Two LSP tunnels, which are opposite in direction, exist between two PEs.
■
The encapsulation types of interfaces of the two CEs are the same and are
■
supported by the MPLS L2VPN.
It is recommended that the VLANs on PEA and PEB which are connected to the
■
CEs be consistent.
LDP remote sessions exist between PEs and are in Operational state.
■
To establish a tunnel, routes to the peer PE are necessary. So you need to configure
IGP (interior gateway protocol) on each router along the path, such as OSPF.
