After the Layer 2 VPN backbone network that runs RIP-1 advertises the local loopbackG
address and the interface IP address, the MPLS LDP session between PEs cannot be set up.
The prompt on PE-A is as follows:
Del Session : EncdecEncode ldp notify msg failure.
Check the MPLS LDP session on PE-A. The display is as follows:
[PE-A] display mpls ldp session
