Multilink PPP Across Multiple DS3

[nsmith5]

We have a router with 2 DS3's.  I have the need to bundle T1's.  The problem is, I only have 1 T1 left on DS3-1 and the other available T1s are ont DS3-2.    Can I multilink across 2 different T1's on seperate DS3?  If so; Is this an OK design scenario and what may be some of the caveats with this setup?>

TIA!

You can do that. However for true predicable performance with an optimal cost, you will need a faster circuit, eg ethernet based, not multiple T1.

Yes thi can be done but you need to take in consideration if these two links are provided by same provider and any timings issues(at link or conroller level) is not present else there will be to many fragments loss and hence too many dropped packets.

Please note that unless configured otherwis, by default MLPPP does not fragment packets, but just ensure in-order arrival.
