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 is 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:
