I want to create 15 subinterfaces in F0/0 and 15 subinterfaces in F0/1 and add each pair to a VFP.
F0/0.1 and F0/1.1 -> VRF1
F0/0.2 and F0/1.2 -> VRF2
F0/0.15 and F0/1.15 -> VRF15
Is it possible? What router support 15 VRFs?
I just tried this on my Cisco 2600 and I stopped trying after I created 35 VRF's and added 35 subinterfaces, each belonging to 1 vrf.
I did get a warning message after the 15th vrf was created telling me that smartinit had been disabled and the system thinks thats a bad idea. I believe your only limited by memory at this point so if your low on memory, you won't be able to keep configuring vrf's but if you have a lot of free memory, you can configure a bunch.
Of course, I found Cisco's recommended numbers on this doc:
About 3/4 down the page is the "PERFORMANCE AND SCALABILITY" section. They only recommend 5 vrf's on a 2600XM.
Although it may be possible to configure 100 vrf's on the box and have everything working, you may run into a problem if you have to call TAC for support.
