Abstract
In one embodiment, a method includes importing a route target for a remote Virtual Routing and Forwarding instance (VRF) at a leaf node in an overlay network, the leaf node comprising at least one local VRF configured thereon, processing routes received for the route target at the leaf node, and installing the routes for the remote VRF at the local VRF at the leaf node to enable inter-VRF communication via the leaf node. An apparatus and logic are also disclosed herein.
