VRF Configuration Notes

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 CAM.

VRF is implemented in a network device by using Forwarding Information Bases (FIBs).

A network device may have the ability to configure different virtual routers, where entries in the FIB that

belong to one VRF cannot be accessed by another VRF on the same device. Only Layer 3 interfaces can

belong to a VRF. VRF is supported on following types of interface:

Physical Ethernet interfaces

Port-channel interfaces (static & dynamic using LACP)

VLAN interfaces

Loopback interfaces

VRF supports route redistribution between routing protocols (including static routes) only when the

routes are within the same VRF.
