RSVP hello extension is configured to detect node failures caused by problems such as signaling error
other than failures caused by link failures.
Configuring Cooperation of MPLS RSVP-TE and BFD
Cooperation of MPLS RSVP-TE and BFD is mainly used for link status detection of FRR. When BFD
detects a link failure, it immediately notifies the failure to FRR, which will then reroute traffic from the
primary LSP to the bypass LSP.
Follow these steps to configure cooperation of MPLS RSVP-TE and BFD:

Configuring the FRR polling timer
The protection provided by FRR is temporary. Once a protected LSP becomes available again or a new
LSP is established, traffic will be switched to the protected or new LSP. After this switchover, the PLR
polls available bypass tunnels for the best one at the regular interval specified by the FRR polling timer:
