Assigning multiple ADSL to GE ports

[Pawel Lenart]

Hi,

I have problem with router and I was wondering if someone can help me.

I have 1 x C2900 router with 3 x ADSL WIC and UC500. I setup 3 x ADSL to access internet and UC500 is connected with 3 telephone lines (plugged into FXO ports). I have 2 x GE on my 2900. 1st GE is connected to switch and 2nd GE is connected to UC500.

I want to setup that traffic from UC500 (SIP) is going through 1 dedicated ADSL line and data (from computers & servers) is going through remaining 2 interfaces only. Can someone tell me how I can set it up.

I would also like to know how I can load balance internet connection going through 2 dedicated data ADSL lines.

These are often asked questions, had you taken the time to search befores asking.

IOS NAT load balancing:

IOS PBR:

Yes I tried to find it but I never used PBR and I wasn't even sure how to descibe what I'm looking for. But your answer was spot on. Thanks.
