Unable to RUN ISIS on 2610

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.

Regards,

Mujeeb

Hi,,, first you need to enable CLNS-routing and then only ISIS will work

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

Re: Unable to RUN ISIS on 2610

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.

Regards, Martin
