Hello All,
I ended up answering my own question, but figured I'd share this and open up for discussion.
It is possible to set a metric with 'route' or `ip route`. What I'm wondering is if there's a Red Hat/CentOS way of assigning a metric in the network-scripts?
Answer: [0] (from 2008) works. ex: METRIC=10
Deployment Guides: EL5 [1] and EL6 [2] do not mention metrics on the previous interface configuration pages.
*** The output from `ifconfig` does NOT show the metric as I set it, but the output from `route` does.
I suppose this is the intended behavior? The default gateway route would have the metric and not the interface.
Notice "Metric: 1" and "UG 10" below.
From my test box (EL6):
~]# ifconfig eth0 | grep ric; route -n | grep G UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.X.Y 0.0.0.0 UG 10 0 0 eth0
