[c-nsp] ISIS / NSF IOS XR

[Frederic LOUI]

Hi,

What state the section related to ISIS with the command "show ip 
protocols" output ?

By default, NSF is disabled. It seems like the output of the "show 
isis adjacency" display if the ISIS neighbors are "NSF capable or not".

IS-IS Router: <ISIS-PROCESS-ID>

...
   Non-stop forwarding: Disabled
   Most recent startup mode: Cold Restart
   Topologies supported by IS-IS:
     IPv4 Unicast
       Level-1
         Metric style (generate/accept): Wide/Wide
         ISPF status: Disabled
       No protocols redistributed
       Distance: 115
     IPv6 Unicast
       Level-1
         ISPF status: Disabled
       No protocols redistributed
       Distance: 115
...

Maybe, just try to enable NSF and re-check the "show ip protocols" output.

Regards,
Frederic
