PurposeCommand or Action
Installs all routes tagged with the value 3 first.spf prefix-priority [ level { 1 | 2 }] { critical | high |
medium } { access-list-name | tag tag }

Step 6
Configuring IP/LDP Fast Reroute
This optional task describes how to enable the IP/LDP fast reroute computation to converge traffic flows
around link failures.
To enable node protection on broadcast links, fast reroute and bidirectional forwarding detection (BFD)
must be enabled on the interface under IS-IS.
