I'm enabling VSS on a pair of 6500's. The documentation I have recommends enabling NSF in the OSPF process which shouldn't be too hard, except further reading about NSF mentions it doesn't work with virtual links. I have virtual links. What I'm trying to figure out is if I can safely enable NSF in OSPF so I get the benefits with my other areas without it breaking my virtual links.

Hi Inayath,
Thank you for the reply.
I'm trying to determine whether it will break my virtual-linked areas outright if I enable it or if I just lose the benefit of NSF for the areas I have that are using a virtual link.
I'd like to enable it if possible without causing an outage.

Hi
I want to enable NSF in EIGRP in 6513 (VSS) for SSO redundancy
I want to know should i also enable NSF in all EIGRP neighbors as well.
Core switch has eigrp neighbors which are User distribution switches (3560E-12SD-E).
So just want to know that enabling NSF in core switch (6513) will not cause any service interruption for the networks which is advertise in EIGRP . I also have redistribute static routes in core switch EIGRP.
Appreciate your repsonse

For anyone in the same position, I implemented this last night. After turning NSF on in my OSPF process, I waited for alarms to start rolling in from my networks reachable via virtual link. None came.
