i have the task to implement voip over a 384 kb/s frame-relay link.
for that i configured frame-relay fragmentation wit 480 Bytes.
does cisco ios only fragment if there is a voice-call or is this fragmentation are active if there is only e.g. internetdownload (http).
i ask for the following reason:
if it is always active there must be a worser performance because of smaller frame-relay pakets and therefore more layer2 overhead.
thanks for an answer !
