We currently have a single T1 from our current provider and I am in the process of moving to a new provider and bonding two new T1's together with Multilink PPP. Our router is a 7204 VXR with a PA-MC-T3 card going into a 2916XL switch. Right now I have both connections up and I have the subnet our new provider gave us set as a secondary ip subnet on the 7204's ethernet card.
My idea is to keep both provider connections up so I can migrate websites, email, dns etc. but am having some routing probs I think. How can I setup my default routes to route traffic in and out their respective gateways? I tried something like this:
ip route 0.0.0.0 0.0.0.0 <current backbone provider gateway>
ip route 0.0.0.0 0.0.0.0 <new backbone provider gateway>
but when I tested it on one of the servers, it wouldn't work. It would act like it was loading msn.com or yahoo but then crap out. The other thing I was thinking about was trying to setup a VLAN, but wasn't sure if I needed to go through that trouble.
Any help would greatly be appreciated.
