Verifying Remote LFA-FRR Configuration on IS-IS

To verify the remote LFA-FRR configuration on IS-IS, use the show commands described in the following examples.

Router# show isis fast-reroute remote-lfa tunnels

Tag aggg - Fast-Reroute Remote-LFA Tunnels:

No Remote-LFA tunnel

Tag Null - Fast-Reroute Remote-LFA Tunnels:

No Remote-LFA tunnel

Tag agg - Fast-Reroute Remote-LFA Tunnels:

MPLS-Remote-Lfa5: use Vl27, nexthop 27.27.27.2, end point 192.168.1.2

MPLS-Remote-Lfa6: use Vl50, nexthop 50.50.50.2, end point 192.168.1.2

Verifying Remote LFA-FRR Configuration on ATM/IMA

To verify the remote LFA-FRR configuration on ATM/IMA, use the show commands described in the following example.

Router# show mpls l2 vc 90 detail

Local interface: AT0/IMA2 up, line protocol up, ATM AAL5 90/90 Basic 1 up

Destination address: 2.2.2.2, VC ID: 111, VC status: up

Output interface: Vlan300, imposed label stack {29 32}

Preferred path: not configured

Default path: active
