Configuring a Tunnel Protection Group

Configuring a Tunnel Protection Group

A configured protection tunnel can be bound to a working tunnel to form a tunnel protection group. If the working tunnel fails, traffic switches to the protection tunnel. The tunnel protection group helps improve tunnel reliability.

Pre-configuration Tasks

Before configuring a tunnel protection group, complete the following tasks:
NOTE:
  • A TE tunnel protection group enhances reliability of the primary tunnel through planning. Before configuring a TE tunnel protection group, plan the network. To ensure better performance of the protection tunnel, the protection tunnel must detour the links and nodes through which the primary tunnel passes.

  • Perform the operation of Configuring Static BFD for CR-LSPs or Configuring Dynamic BFD for CR-LSPs to implement fast switching at the millisecond level.

Configuration Procedure

Except that configuring the protection switching trigger mechanism is optional, other configurations are mandatory.
