Enabling SSO also enables NSF?

[guillermo.ruiz]

I have SSO enabled on my 6509E, but I'm not sure if NSF is enabled.

Maybe I am a little confuse  to understand what is NSF helper and NSF aware that my switch displays, as follows:

switch#sh ip ospf nsf

Routing Process "ospf 1"

IETF NSF helper support enabled

Cisco NSF helper support enabled

switch#sh ip prot

*** IP Routing is NSF aware ***

Someone can provide some help?

Thanks,

guruiz

NSF-aware if it is running NSF-compatible  software. A device is said to be NSF-capable if it has been configured  to support NSF; therefore, it would rebuild routing information from  NSF-aware or NSF-capable neighbors.

You enable NSF in the routing protocol, if supported.

For example:

router ospf 100

nsf

thanks Reza,  thanks Joseph,

Your answers are so kind and helpful.

I only have a doubt about NSF helper, do you know what is this?, due it is enabled before I configure NSF under OSPF.

switch#sh ip ospf nsf

Routing Process "ospf 1"

IETF NSF helper support enabled

Cisco NSF helper support enabled

You don't need to

All you have to do enable NSF under OSPF on all the routers that are NSF aware.
