From 2ce90bb10faf125d040503adc124373910d11f13 Mon Sep 17 00:00:00 2001 From: Chirag Shah Date: Tue, 26 May 2020 11:43:14 -0700 Subject: [PATCH] zebra: dup detected mac avoid update to bgpd When a MAC is detected duplicate on a local learn event (with freeze action), do not send update to bgp to advertise into evpn control plane. With evpn mh, inform_client flag is set and sends notification to bgp albeit dup detect is set. Check mac are detected as duplicate before setting inform_client to true.
