Abstract
Techniques described herein provide for fast updating of a forwarding table in a single active multihoming configuration. A first network device that is not connected to an ethernet segment (ES), receives a plurality of ES routes (e.g., EVPN type-4 routes) from a plurality of network devices that are connected to a host via the ES. When connectivity is lost to a designated forwarded for the ES, the first network device performs a designated forwarding election algorithm based on the plurality of received ES routes, to identify that a second network device of the plurality of network devices is designated as a new forwarding device. The first network device modifies an entry in a forwarding table to indicate that the host is now reachable via the second network device.
