Abstract

In general, techniques are provided for described herein that extend existing Ethernet Virtual Private Network (EVPN) protocol signaling mechanisms so that local, multi-homing PEs couple to an Ethernet segment can definitively convey their primary/backup designated forwarder (DF) status to any remote PE of the EVPN. In one example, this is accomplished by utilizing a new extended community attribute to each Ethernet A-D per EVI route advertised by each of the multi-homing PEs to specifically carry the advertising PE's primary or backup status. As such, any receiving remote PE need not rely on the arrival of individual MAC routes from a new primary PE and withdrawal of MAC routes from a former primary PE to update its forwarding information.
