Configuring Manual TE FRR

Configuring Manual TE FRR

Manual TE FRR is a local protection mechanism used on MPLS TE networks. TE manual FRR switches traffic on a primary MPLS TE tunnel to a manually configured bypass tunnel if a link or node on the primary tunnel fails.

Pre-configuration Tasks

Before configuring manual MPLS TE FRR, complete the following tasks:
  • 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.

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 and changing the PSB and RSB timeout multiplier are optional, other configurations are mandatory.
