NSF in an EIGRP network.

[whitbych1]

I have a 6509 that I am installing a redundant 720 Supervisor module. EIGRP is the routing protocol used between my layer 3 devices. The other 3 devices are 3750s running 12.2(25)SEE IOS. Currently this IOS does not support NSF. Which IOS should I use on my neigboring 3750s in order to make sure stateful switchover occurs in the case that my active Supervisor module fails?

Go to this URL:

It is Cisco's feature navigator and from there you can input the NSF feature for EIGRP and get all the IOS levels and for what platforms you need...Good Luck..Pls rate..

NSF was introduced in 12.2(25)SEC so the problem is actually the lack of NSF support in your feature set. You need at least IP Services to get NSF awareness. GL!
