Create gateway for WAN interface not device

[wilson419]

Hi all,

We've recently swapped our Draytek 3900 routers for Cisco ISR 4431 and have got them configured on a single WAN line and all working fine however we want to introduce a second WAN line but whereas on the Draytek each WAN connection had it's own gateway I can't seem to find how to do it on the Cisco ?

Both lines are static IP so we need to add a gateway which currently is the one for the main "current" line but how do I enter a gateway just on the port that the second WAN is on (gigabitethernet0/0/0) 

Also as a second part of the question (and this isn't as urgent) but what way do we configure Ciscos to "failover" to the second line if the main one goes down ?

Thanks in advance

Ian

Just looking further to this I think I need to set the default route 0.0.0.0 with a slightly higher metric for the second WAN for it to "failover" is that right ?

Still can't find how to add a second gateway though
