Static inter-VRF routing

Static inter-VRF routing involves creating static routes in one VRF instance whose egress VLAN is in a different egress VLAN. These static routes must specify both the egress VLAN and next hop IP address.

The following diagram illustrates use of static routing to achieve inter- VRF communication in VRF-lite.
