WAN traffic problem

[sikek]

We have an 3640 cisco with three T-1 links. But all traffic comes in on one interface. And all traffic goes out on one interface. How can i config the traffic to use both circuits?If you need to see the config let me know thanks for any help.

A#
30 second input rate 0 bits/sec, 0 packets/sec
30 second output rate 620000 bits/sec, 156 packets/sec


B#Available Bandwidth 1536 kilobits/sec
5 minute input rate 1508000 bits/sec, 293 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec


C#Available Bandwidth 1158 kilobits/sec
30 second input rate 0 bits/sec, 0 packets/sec
30 second output rate 625000 bits/sec, 156 packets/sec

Are all T-1's from the same ISP? Do you have a specific block of IP's that is being routed to and from all 3 T-1's. Something as simple as equal weight routes on the ISP and on your router would work.

No one T-1 is for Verio the other two are for Epoch. Here's the config on the router.thanks for the quick reply rudeboy.

How can i change this config to make use of all circuits to there max?

ip load-sharing per-packet on the serial interfaces
this is the key statement. setup your routes

Just to make sure i got you correctly i should enable ip load-sharing per-packet on all interfaces. Two of them already has it enable. So all i need to do is enable it on the serial 1/0 right?
