how to set preference and metric when configuring a satic route

Kanyong · 10-30-2008, 02:19 PM

I am trying to figure out how to set preference and metric for a static route.

Based on the manual of "ip route" command, seems like both metric and preference options are acceptable. But when tried, I got failure. i,e

ip route add 1.1.0.0/16 via 2.2.2.2 metric 1 preference 5
ip: either "to" is duplicate or "metric" is garbage.

And, the linux "route" command only accept metric option. I can do the following succesfully.

route add -net 1.1.0.0/16 gw 2.2.2.2 metric 1

can anyone help me out?

Thanks a lot,
Yong

Using the right values for network and gateway the command finishes OK for me (iproute 2.6.18 and recent kernel 2.6)?..

I'm not sure where you found 'preference'
But metric can be used to specify routes. The system will preferentially use the route with the lower metric so that will be enough.

Have a look at http://publib.boulder.ibm.com/infoce.../chgtcprte.htm
