VPLS Features

When T-LDP is used to signal service parameters between two PEs, which MTUs are required to match?

  • A SAP MTUs
  • B SDP MTUs
  • C Service MTUs
  • D Path MTUs
Explanation

For a T-LDP-signaled Layer 2 service, the advertised VC MTU is derived from the service MTU and must match the MTU advertised by the remote PE; otherwise, the spoke SDP remains operationally down. SAP MTUs and SDP path MTUs are local constraints and do not need to match between PEs.
