From fa4966f4dba8aab9fe17ac5711071e9e56384079 Mon Sep 17 00:00:00 2001 From: Dan Sneddon Date: Mon, 27 Apr 2015 18:39:37 -0700 Subject: Add flag for DEFROUTE=no in ifcfg files to ignore DHCP gateway When multiple interfaces are configured with DHCP, and more than one interface receives a gateway from the DHCP server(s), the resulting default gateway on the system is unpredictable. This change adds the "defroute" boolean to the configuration syntax for os-net-config. Any interface type may be marked so that the gateway received from the DHCP server will not be eligible as a default gateway for the system. This only works for ifcfg files, /etc/network/interfaces lacks an equivalent option.
