Actually, I should clarify. We need to know if it can take two full 
feeds in a VRF (VRF lite, with minimal management only routes in the 
global table). These are an unusual platform for us so I don't have any 
spare that I can put into a lab.

Despite the PXF hardware feature I don't think they use TCAM to store 
the FIB, so I guess the amount of memory consumed is going to depend on 
the IOS release. These are currently running 12.2(28)SB5.

I've seen this page but there's no info regarding maximum supported routes:

Hopefully someone else out there has a similar configuration and they 
can post the memory usage.

Thanks,

Sam
