Does peering at an ATM MAE require a router that does ABR?

Thu Mar 1 21:36:03 UTC 2001

In the past, the MAE ATM switches ran ABR where you specified the MCR
and traffic was policed at a PCR of 2xMCR, although almost no one at
the MAEs actually used ABR on their connections. Almost everyone used
VBR-nrt and many did not even realize that the use of ABR could have
been beneficial.

With "best effort" PVCs, this really becomes moot although these are
still technically ABR.
