Configuring Primary and Secondary PWs

Configuring Primary and Secondary PWs

Context

You can configure primary and secondary PWs to protect services on the PWs.

  • On the network where CEs are symmetrically dual-homed to PEs, configure one primary PW for each of the primary and secondary paths. The primary and secondary paths can be configured with different types of PWs.

  • On the network where CEs are asymmetrically connected to PEs, configure primary and secondary PWs for the primary and secondary paths respectively. The primary and secondary PWs must be of the same type.

Devices support only dynamic primary and secondary PWs.

Perform the following operations on the two PEs of a PW.

Procedure

  1. Configure dynamic primary and secondary PWs on the PEs. For details, see Configuring a Dynamic PW.

    NOTE:
    • Primary and secondary PWs must have different VC IDs.

    • Primary and secondary PWs must use the same control word; otherwise, many packets may be lost during service switching.
