I have a cisco 7200 and 2600 with IOS 12.2(5) installed and have observed a problem when MLPPP and Interleaving is configured.
firstly, the ppp multilink fragment-delay command, has only one setting.
Any setting above 50ms fragments the ppp packets into frame-relay frames that are 1510bytes long.., anything below 50 is 56 bytes.
I would have expected a bit less of a drastic change, and from a document about implementing a WAN it seems to suggest , that for a 256Kbps link speed an 8ms delay would produce a 256byte fragment. It seems that there is something wrong in the way the the fragment-delay command is claculating the fragmentation required.
Also, is there a way where I can choose the fragment size, since this is a frame-atm connection a 56 byte fragment is one and a tiny bit ATM cells.. I'd like to pack the cells as tightly as possible.
Thanks In Advance,
Adam
