my ISP is providing point-to-point connectivity between my 2 offices,with two 2Mbps line, which will be ethernet output, so i will connecting it on my Switch directly, so if i do etherchanneling, across WAN (being an Ethernet Output) will it work,can i achieve 4Mbps?(being a WAN link of same bandwidth)

i know i can configure virtual templete which i hav already done with serial ports.

on LAN i hav done etherchanneling between the 3750's.

you will have ethernet connection at both the end right!!! if it is so then i think you will have static route with the same AD will be the solution or you might have option of using the tunneling and then routing protocol on it...

if you are talking about the MULTILINK PPP then its not possible on Ethernet...

let see for other expert replies...

Different providers ?

That's a good question but I don't see why not. As long as they are tunneling PAgP or LACP, it's up to you to form the etherchannel. They have to use the same L2Prototocol tunneling.

In total honesty, etherchannel over 2 x 2 mbps links is something unheard of before. Beside all the obvious problems (large mismatch in speeds, no possibility of QoS) you can end with poor balance due to the algorithm used in switches.

I would never recommend such a design, the proper way to use WAN circuits is with routers in a routed configuration.
