how to configure IS-IS on 1720 Router

[svermill]

No can do. I recently researched that issue and a TAC CCIE wrote to tell me that IS-IS support is not planned for any time in the future on low-end routers such as 1720. I think the 2500 is where IS-IS support begins in IOS. Even then, I think you need IP Plus.

No, you need an Enterprise feature set.

Steve ya beat me to it.!

need a 2600 to run IS - IS

[xavierchang]

That's not true. I've been running IS-IS on 2500's for years.

No arguement, Can't buy a 2500 from cisco hardly,

The main point is that its not supported on the 16 thru 17 series of routers.
