I have a 10MB MetroE connection that is plugged directly into a port on the 3750. If this connection goes down I want to route the traffic over 2 bonded t-1's that are connect to a cisco router. What is the best way to do this? Can this be done with the 3750 ip base switch?

Here you need to run dynamic routing protocol.In IPBASE feature set, this is possible with RIP, but , if you look in perspective of scaling & convergence speed, you would like to prefer EIGRP, OSPF.

But IPBASE does not support EIGRP,OSPF in CAtalyst 3750, so you need to have IP SERVICES Feature set, if you want to run EIGRP, OSPF.

HTH...rate if helpful..

If you know the destined Networks Sitting at the other end, you can reach your objective by configuring static routes to those destination with Lesser administrative distance pointing to 10Mbps link. and with Higher adminsitrative distance pointing to Your router.

Untill your 10 Mbps link was available , your packet will be routed through it. If it goes down it will be routed to Router to reach the destination.

Note - Before that Enable routing functionality in your switch by configuring

ip routing command.
