I am confused a little bit. I dont see fast-reroute comand under ospf configuration level. According configuration guide and feature navigator it must be. But it is not
Routers ISR4431 and ISR4331 with IOS 16.09.04 and 16.08.01
And both does not have this command.
But if you look at csrv with the same software version this comand is present.
Can anyone explane it to me? What's the point?
Open Shortest Path First (OSPF) supports IP FRR only on platforms that support this feature in the forwarding plane. See the Cisco Feature Navigator, http://www.cisco.com/go/cfn , for information on platform support.
Dont have ISR in hand for testing, what is the version of code running on this ISR ?
As you can see above the feature is present for this platform
, what is the version of code running on this ISR ?
As I have already said Router ISR4431 with 16.09.04 and ISR4331 with 16.08.01
Can you confirm your license version?
