VRF Configuration Notes

On E-Series routers, Dell Force10 VRF supports up to 15 VRF instances: 1 to 14 and the default VRF (0).
Although there is no restriction on the number of VLANs that can be assigned to a VRF instance, the total
number of routes supported in VRF is limited by the size of the IPv4 FIB table in the CAM.
VRF is implemented in a network device by using Forwarding Information Bases (FIBs). Each VRF uses
one FIB.
A network device may have the ability to configure different virtual routers, where each one has its own
FIB that is not accessible to any other virtual router instance on the same device.
