FRR configuration example
Network requirements
On the primary CRLSP Router A—Router B—Router C—Router D, use FRR to protect the link Router
B—Router C.
Use RSVP-TE to establish the primary CRLSP and bypass CRLSP of the MPLS TE tunnel based on the
constraints of the explicit paths. The bypass CRLSP uses path Router B—Router E—Router C. Router B is
the PLR and Router C is the MP.
Configure BFD for RSVP-TE between Router B and Router C. When the link between Router B and Router
C fails, BFD can detect the failure quickly and notify RSVP-TE of the failure, so RSVP-TE can switch traffic
to the bypass CRLSP.
