Hi, We need more bandwidth for the internet connection(Dedicated internet connection), so our ISP (Qwest) is setting us up with a second T1 line, which will be "bonded" with the original T1. We will be using the same existing addresses for simplicity. However, I have never done this before and can anyone show me the sample how to configure a bonded T1 on a 3600 Cisco router. Thanks...
You can do it a couple of ways. It would be best to ask Qwest how they are going to do so you can match, and I'd bet they'd be able to give you the correct config at the same time.
If you want to research, you can do MPPP, or CEF load balancing. Or even MLFR.
All of them are quite popular in the ISP environment for doing that.
Multipoint PPP is where the PPP over a single T-1 line becomes PPP spread over multiple T-1 lines. Make sure that your T-1 controller or WIC supports this.
