RE: What is the max # of Sync Serial interfaces that can be multilinked?

I believe that IOS has a hard ceiling max limit of links into a single
MLPPP bundle of 64. However, there are several possible hardware
limitations that can make this shrink down to as low as 4.

I believe that the only way to get to the larger #'s is to use something
like 2T3 Port Adapters in the 7500/7200 routers.

4 isn't the max. But it all depends on where you handle it. DigitalLink
has an Imux that will handle 7 T-1's for a 10meg circuit. (If memory
serves, it's a DL3800 or something like that)

But for software-related multilink, which I believe is what the question
was asking, 4 is the max (AFAIK) mostly because of the software
processing that goes on in order to maintain the bundle.

That may be an evolving thing as well, depending on the equipment/memory
you have.

Even I know few other vendors , but the max is 4T1s. Can someone explain
why is this limitation?.

Does anyone know definitely the max # of T1's (Syncrhonous Serial)
interfaces that can be inverse multiplexed using Multilink PPP. I
checked the Cisco Web site and I saw 4 ?
