From c97b4aca0db8d84b17ceb03a14ab44346a2b3466 Mon Sep 17 00:00:00 2001 From: John Lo Date: Tue, 7 Nov 2017 17:23:49 -0500 Subject: Fix SHG handling for ARP/ICMPv6 received from BVI in a BD This change makes sure ARP/ICMPv6 brodcast packets received from the BVI of a BD can be flooded to all remote VTEPs via its VXLAN tunnels irrespective of SHG setting. Similar processing was done for unicast packets already and needs to be extpanded to ARP and ICMPv6 broadcast packets.
