2 ip's one name

[Greg]

Hi 

I have two radius servers one on either side of a nas/router(cisco 5300)

I would like this router to look like ts2 from either side of the
network.
The radius server sees the interface that is on it's side, and resolves
off that name. So our records are cleaner I would like to have this
router to have the same name for both its ip's 
Is this possible.

Thanks Greg Dickson
