[j-nsp] general question on VRFs and FIBs...

[Derick Winkworth]

All:  

I'm trying to find an archived discussion or presentation discussing why exactly the industry generally settled on having a separate FIB table for each VRF vs having one FIB table with a column that identifies the VRF instance?  I'm not finding it, but I'm guessing its because of performance issues?    

Any pointers would be great or perhaps someone on the list knows why? 

Thanks!  Derick
