Configuring the Pseudowire Status TLV

Step-by-Step Procedure

  1. Navigate to the [edit protocols l2circuit] hierarchy level to configure Layer 2 circuits over MPLS.

  2. Set the address for the neighbor provider edge router;, this example uses a fictitious address,

  3. Specify the name of the interface forming the Layer 2 circuit; this example uses xe-0/0/0.

  4. Enter the pseudowire-status-tlv statement.


    You need to configure the virtual-circuit-id statement in order for pseudowire-status-tlv to work.

  5. Set the virtual-circuit-id statement to identify the pseudowire as regular or redundant. The identifier value can range from 1 through 4,294,967,295.

  6. Check your configuration by entering the show command.
