I am attempting to bond a couple of T1s into a single pipe for the network. It's supported by the ISP (SpeakEasy), but they won't support a config on a router they don't provide. As far as I know, this SHOULD be working, but can someone else take a look at this and tell me if I'm doing something wrong? I had to adapt the config from one I knew of on an 1841. Here's the current config:

The config looks fine but can you let me know whether it is necessary to run Frame relay encapsulation on your links
Configs would have been easier with a plain PPP encapsulation

Well, it's hard to say conclusively. Like I said, I'm just working off of information the ISP gave me, and they listed in a partial sample config running it with frame-relay encapsulation. Is this something I can change on my end without affecting the other? I mean, is it possible to change it to ppp without having to get buy-in from the ISP?

Agree with Narayan, but considering that speakasy, as dynamic and nice ISP they are, is still a second tier ISP, so they are based on frame relay for T1-class customers, hence the need for MLPPP over frame relay.
It should work.
