From 483eef9dd2ff45524bfd0fe8eba1b8ba1fad58a4 Mon Sep 17 00:00:00 2001 From: Donald Sharp Date: Fri, 26 Aug 2016 09:40:08 -0400 Subject: [PATCH] pimd: Further refinement of switch on a stick The original modification to allow the RP to receive packets on the incoming interface when it has no outgoing interfaces was a bit aggressive and turned all register events into a join event. This further divides up the code to do the right thing in each situation.
