Hi All,
I have a Cisco 2610 Router having IOS version 12.2(29a). I want to run isis protocol on this router but unable to do this. When I enter " router isis " command in configuration mode then the prompt does not change to Router(config-router)# mode. Kindly help me in this regard.

Make sure you have a enterprise IOS loaded. I don't think ISIS is in any non enterprise image.

you need to enable clns routing , Normally in cisco router " IP routing " is enable by default, but in ISIS you need to enable " clns routing" after that you can confire ISIS.
I hope this will help you out.

Hello,
just to clarify one thing: CLNS routing is NOT needed to start ISIS. A config could look like this:
ip routing
no CLNS routing
! for clarity, will not be visible as it is a default
interface Loopback0
ip address 192.168.168.192 255.255.255.255
interface Ethernet0
ip address 10.1.1.10 255.255.255.0
ip router isis
router isis
net 49.cafe.1921.6816.8192.00
passive-interface Loopback0
metric-style wide
This will enable integrated ISIS only for IP. You can check this with "show ip protocol".
So the general problem one faces with ISIS from an IOS perspective is the proper feature set as already pointed out in a previous post.
Hope this helps! Please rate all posts.
