Combining three t-1 as one

[sikek]

I wanted to know what commands could I use to combine three t-1 as one?

If a T1 is 1.55 i.e x3, so I speculate you configure your bandwith like wise.

What layer two tech are you using?

See multilink for cisco routers this can help you.

Did some research and you need special device. Look at the Easter Reseacrh, DNX devices.

If your router can support 3 WIC slots, or take 3 T1's in to it physically in any fasion, then do this (my example below is for a 2691, so label your slots accordingly for your router):

interface Multilink1
ip address x.x.x.x x.x.x.x
ppp multilink
ppp multilink fragment disable
ppp multilink group 1

interface Serial0/0
no ip address
encapsulation ppp
service-module t1 timeslots 1-24
ppp multilink
ppp multilink group 1
!
interface Serial0/1
no ip address
encapsulation ppp
service-module t1 timeslots 1-24
ppp multilink
ppp multilink group 1
!
interface Serial0/2
no ip address
encapsulation ppp
service-module t1 timeslots 1-24
ppp multilink
ppp multilink group 1

So, as you can see, you will not put any IP info on the T1 interfaces themselves, only on the MultiLink interface. This is also where you would put routing information, etc. Think of the multilink interface as the interface to put all IP info, and the Serial interface as the interfaces that do nothing more than physically terminate a T1.
