Bandle t1

[encrb]

The company is adding a second internet t1 and I have a cisco 2620 12.3 (25) with 2 wic- dsu- t1 v1

The 2 t1 are clear channels.

I am not sure is the default route should be 2 lines to the serial interface or one line to the multilink interface.

ip route 0.0.0.0 0.0.0.0 Serial0/0
ip route 0.0.0.0 0.0.0.0 Serial0/1

OR

ip route 0.0.0.0 0.0.0.0 Multilink1


Here is my interfaces.

I would just put

ip route 0.0.0.0 0.0.0.0 x.x.x.x <-- wan gw address

It make sense for me, thank you for your help
I will try the gw IP instead.

Remember, the ip route statement is a layer three statement. Once you make your T1s part of a multilink group, the multilink interface is your layer three component.

Regardless, I would do as Jeter suggests and just point to the layer three destination, not any particular interface.
