Hello,

1. For a static VC, the prerequisite for the VC to go up is that:    

  • The local AC is up.    

  • The tunnel is up.

2. For a dynamic LDP VC, a PW can go up only when the following conditions are met:   

  • The local AC is up.   

  • The tunnel is up.   

  • The LDP Session is up. 

  • The MTUs, VC types, and control words at both ends are the same.   

  • VC IDs are the same.

You can run the display mpls static-l2vc interface command to check the configuration.
