Bundling Multiple T1's across multiple routers.

I have an upcoming install that includes two sites with 2650's per site and a total of four T1's between the two sites.

I'm wondering if Multichassis Multilink ppp would fit the design to get the most effective throughput, but I've only seen MMPPP using in dial solutions.

Can someone point out documentation on how to do this if applicable?

Re: Bundling Multiple T1's across multiple routers.


You said you had 2650's on each site, but you did not say how many. If you only have one at each site, just do normal PPP. The URL

will give you basic information on what you want.

Re: Bundling Multiple T1's across multiple routers.

Multi Chassis mlppp will be useful only when you have multiple routers at the receiving side, receiving the call..So if you just have one router with the multiple T1 lines at each site then i think the "dedicated T1" lines will give you better throughput..

You can group multiple T1 at each site in a "multilink group".

Here is the sample config

Note that the config for T1 and E1 is the same..

Now if you still want to "dial", then just go for regular "ppp multilink" under the T1 line..rather then sgbp/multichassis.

Re: Bundling Multiple T1's across multiple routers.

Well, let's be honest, the Cisco implementation of MPPP for dedicated links bites. It's just very flaky. I know you work for Cisco and you don't want to admit it, but you know it's true. If you're just talking about load-balancing multiple dedicated links on one router, use CEF, end of story.
