Re: MLPPP over MPLS

Overall, MLPPP may work fine with MPLS as long as you have single virtual circuit from each physical circuit.
Such as T1 channel from Channelized DS3...
But you have to use sub-interface (logical interface) other than sub-channel from channeliezed circuit,
you may have some problem.
If you want to use QoS with MLPPP, some cases you may have to disable CEF because of side effects.

Overall, what I was recommended by Cisco source, is, if possible, to use MLFR instead of MLPPP for MPLS integration.

If you need more information, you can contact your local Cisco System Engineer, and he/she will give more information to you.

than N=2.  There are a number of ways to bond NxT1 together, including
MLFR and IMA, and we've generally used IMA for ATM and MPLS services
and CEF for Internet.  IMA has the annoyance of extra ATM overhead,
but doesn't have problems with load-balancing or out-of-order
delivery, and we've used it long enough to be good at dealing with its
other problems.
