I have a customer with the typical hub and spoke frame-relay config. I
implemented FRTS for BECN adapting. The problem with incrementing BECN's
went away. I am still wrestling with packets being marked DE at the remotes
(as seen below). Based on the "DE in packets" I am thinking that there is a
congestion issue at the hub location since several 768k pipes empty into a
t1. Any way to throttle the traffic back further? Should I drop the CIR and
MIN CIR in the FRTS? Any other ideas? Btw, this counter was cleared a day
ago and I already have a ton of DE pkts.
Thanks,
Keith
