Configuring Auto TE FRR

Configuring Auto TE FRR

Auto TE FRR is a local protection technique and is used to protect a CR-LSP against link faults and node faults. Auto TE FRR does not need to be configured manually.

Pre-configuration Tasks

Before configuring auto TE FRR, complete the following task:
  • Configure a dynamic MPLS TE tunnel. For details, see Configuring a Dynamic MPLS TE Tunnel.
  • Enable MPLS, MPLS TE and RSVP-TE in the system view and interface view of each node along a bypass tunnel.
  • Enable CSPF on a PLR.
NOTE:

Perform the operation of Configuring Dynamic BFD for RSVP to implement fast switching at the millisecond level.

Configuration Procedure

Except that configuring a TE FRR scanning timer, changing the PSB and RSB timeout multiplier, configuring auto bypass tunnel re-optimization, and configuring interworking with other vendors are optional, other configurations are mandatory.
