From 57b5860f013953ce161d05302e05370db9cd6ee2 Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Sat, 15 Jul 2017 07:37:25 -0700 Subject: FIB path preference Paths are given a preference, lowest value is 'best'. Only paths that are up are up contribute to fprwarding - that's unchanged. What's new is that of the path's that re up only those that have the best preference contribute. A poor man's primary and backup. It's not true primary/backup function because the FIB must converge before the lower preference paths are used.
