Re: Does 2610 router support T1 Trunking

mhiers · ‎03-12-2002

We have several 2610 routers and would like to know if they support the trunking of 2 or more T1's. If so what would be the memory and IOS needed?

What exactly do you mean by T-1 trunking?

mhiers · ‎03-13-2002

Having 2 or more T1's connected to the same routers over a WAN link. This will give you a 3meg pipe between the sites. It will also allow you to keep working if one of the T1's fail but with half the bandwidth.

This would be MultiLink PPP, and yes the 2600 can do it. Equal cost IP load balancing can achieve a similar result without the extra CPU resources that MPPP requires (provided your running fast-switching or CEF).

What type of WIC would I need to Support the 2 T1's coming into the router? The T1's are from the ISP and the router sits on the outside of the PIX.

Take a look at this URL.

You will need a NM- something module for the large slots and then choose a WIC for your needs to put in the NM module(s). You have the choice of either ones with/without CSU's.
