Hi,
I would like to know the number of VRFs supported on 7300 and 7400 routers. I have heard it is 100 in 7400 series routers.
Thanks,
Prakash

There is no hard limit on the number of VRF these two devices can handle. Rather, the limit on the # of VRF is determined by many factors such as # of routes per VRF, routing protocol used b/w PE-CE, amount of memory installed on the PE. I had once had a document describing the exact details but can't find it anymore.
I will let you know if I can put my hand on it.
Hope this helps,

Hi
I found the presentation you probably were telling about. It is a presentation from the networkers.
It says the following:
~ 60 - 70 K per VRF
(32K for base VRF control block, other memory such
as CEF, TFIB overhead, IDB's and so on(
~ 800-900 Bytes per Route
(Includes CEF, TFIP, and RIB memors in BGP)
But basically it is dependent on many things as you mentionded.
Hope that helps you.
