TAC Are You Listening (IS-IS Question)

I hate to open a case just to ask this question. It would appear that there is no IS-IS support on 1600 or 1700 series routers. Is that in the future or just something that will not be supported?

Re: TAC Are You Listening (IS-IS Question)

Hello Vince,

I am currently running 12.1(9) IP Plus. I went to the feature navigator and selected IS-IS. The next step would be to select the platform. The list for this feature starts at 2500 and goes up. Also, even with IP Plus running, the command 'router isis' can be entered - with no effect on the actual config. Finally, none of the isis commands at the interface level are valid. So it definatley looks as if this is not yet supported for lower end routers like the 1700 series. I found that odd, since even BGP 4 is included with IP Plus.

Thanks,

Scott

You are probably correct. Get the checkbook out.

To William: In order for isis to function, at a minimum you need to configure a NET (network entity title) under the router isis process, then configure the interface(s) that'll participate in iso zones. Refer to isis documentation.

ISIS. the 16/1700's don't show up. The lowest level

Re: TAC Are You Listening (IS-IS Question)

Well, the TAC never responded and I never opened a case. As you can see from this thread, though, both Vince and I concluded from the Feature Navigator that IS-IS support currently stops at the 2500. I suspect that eventually IS-IS will show up in an IP Plus feature pack for the lower end routers someday (if BGP did, why not IS-IS?). If it is imperative that you run IS-IS, you may try opening a case with TAC. They may have a trick up their sleeve.

Good luck and let us know if you find a way to pull this off.

Scott,

IS-IS requires the Enterprise (-j-) IOS image and there is none currently available for 1600's or 1700's.

Originally,the "IP" version for these platforms did notinclude OSPF or BGP, these protocols were later added to the "IP Plus" version.

I am checking internally about any plans for also supporting IS-IS in the "IP Plus" version and will let you know what I find out.

You can email me directly to cawu@cisco.com to follow up on this conversation.

Best Wishes,

Catherine

Catherine,

I will e-mail you offline. Many thanks for taking the time. I was relatively certain that IS-IS would eventually trickle down to the lower platforms.
