How do you link 4 internet T1's on a 7507?

[pbunchuk]

We are changing internet providers and replacing our fractional DS-3 with 4 T1's. I have a 7507 with a PA-MC-4T1 interface. Can anyone point me to a sample config for bundling the T1's?

Thanks,

Paul

You can use distributed multilink PPP to bundle the T1s together :

OR

You can use distributed CEF per packet load balancing over the 4 T1s:
