From daa59739d86305c11eb05af167cad82cfd22a017 Mon Sep 17 00:00:00 2001 From: Arata Notsu Date: Fri, 10 Jan 2014 19:54:10 +0900 Subject: [PATCH] Fix ValueError in ip_lib.IpRouteCommand.get_gateway() As metric is not necessarily the 5th word of the gateway line, the method should search the string 'metric' in the line and pick the next word as the metric value.
