FRR in NX-OS

[gemv44]

Hello, I am trying to simulate Fast-Rerouting in a NX-OS device running the ISIS protocol, but I can't resolve it because the command fast-reroute per-prefix level-2 all doesn't appear.

Could someone help me?

Hello @gemv44 

Which platform please ? and which NX-OS version ?

""Fast reroute link and node protection requires an MPLS license. For a complete explanation of the NX-OS licensing scheme and how to obtain and apply licenses, see the Cisco NX-OS Licensing Guide.""

Thanks.

Thak you for your answer. I tried in NX-OS 7.3 titanium and NX-OS 9500 10.1.2.

 I want to apply fast reroute over ISIS protocol, but the command fast-reroute is unrecognized. Your suggesting is for MPLS-TE, you think is the same licensing problem?

Code that I applied:

router isis pruebas
net 49.0010.0000.0000.0003.00
reference-bandwidth 100
is-type level-2
fast-reroute per-prefix level-2 all
