Usage guidelines
FRR provides a quick link or node protection on a CRLSP. FRR traffic switching can happen in as fast as
50 milliseconds, minimizing data loss.
After FRR is enabled for an MPLS TE tunnel, once a link or node fails on the primary CRLSP, FRR reroutes
the traffic to a bypass CRLSP and the ingress node attempts to set up a new CRLSP. After the new CRLSP
is set up successfully, traffic is forwarded on the new CRLSP.
After FRR is enabled for a tunnel with this command, the label recording function is automatically
enabled for the tunnel, regardless of whether you have configured the mpls te record-route label
command.
In the same tunnel interface view, FRR cannot be used together with the mpls te resv-style ff command.
Examples
