Dual Wan connections need advice.

[StretchedTech]

I have one T-1 line coming into my building. Soon I will have another T-1 coming into my building. I am looking for a router that will handle both T-1's and do load balancing. I have a Sonicwall Firewall that I would like to keep as is. Basically I am looking for a router that I can plug into my network and will take both T-1's and do load balancing with little or no setup. I am farely good with cisco routers. Any advice or suggestions. Thanks in advance.

A 2600XM would work, suggest a 3600 for better performance though. Especially if you intend on using two different ISP's. If that is the case you want to think of using BGP.

I'm assuming you are getting both T1 from the same ISP, if so:

Get your ISP to give you a multi link connection. (we use QWEST)

And use this config

interface Multilink1
ip address w.x.y.z 255.255.255.252
load-interval 30
no cdp enable
ppp multilink
no ppp multilink fragmentation
multilink-group 1
!
interface Serial0/0
bandwidth 1536
no ip address
encapsulation ppp
no ip mroute-cache
load-interval 30
no cdp enable
ppp multilink
multilink-group 1
!
interface Serial0/1
bandwidth 1536
no ip address
encapsulation ppp
load-interval 30
no fair-queue
no cdp enable
ppp multilink
multilink-group 1
!

I've got this running on a plain old 2611, it seems to peak at 30% (Sho proc)

I have a slightly different question...

Were going to have a remote site with 2 T1 circuits.


1 Circuit will be connected to my main location
1 Circuit will be connected to an ISP...

How feasable will it be to have all traffic not dest'n for my Main building come through 1 T1, and all traffic dest'n for Internet through the second connection...


Okay, here's another wrench I can throw into the mix, my main site has it's own connection to our main campus who also has a I2 connection (University Internet2 backbone)

How hard would it be for me to have it forward any I2 traffic through my link so I can forward it to main campus...

Any Thoughts?

What if you have T-1 from two different ISP? Can I use multilink config for my 2610XM?
Thanks for support.
