From 6f6311560380d0e992f710558e213df1b098ef94 Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Tue, 3 Oct 2017 08:20:21 -0700 Subject: Distributed Virtual Router Support A distributed virtual router works by attmpeting to switch a packet, but on failing to find a local consumer (i.e. the packet is destined to a locally attached host) then the packet is sent unmodified 'upstream' to where the rest of the 'distributed' router is present. When L3 switching a packet this means the L2 header must not be modifed. This patch adds a 'l2-bridge' object to the L3 FIB which re-injects packets from the L3 path back into the L2 path - use with extreme caution.
