Abstract

In one embodiment, a method comprises receiving traffic to send from a router to a host in the fabric edge network, wherein the fabric edge network comprises a plurality of switches and an inter-switch link (ISL); and sending the traffic from the router to the host via at least one of the switches based on the downlink connectivity of the host. Sending the traffic from the router to the host is performed without sending the traffic through the ISL. Sending the traffic from the router to the host comprises sending the traffic through the ISL when there is a link failure on a path between the router and the host.
