What functionality does PVC give you that the ethernet VLAN does not?That´s quite easy. Endpoint liveness. A IPv4 host on a VLAN has no idea if the guy on the "other end" died until the BGP timer expires. FR has LMI, ATM has OAM. (and ILMI)
FR LMI and ATM ILMI are so notoriously unreliable at endpoint liveness that FR EEK and ATM OAM became necessary. Be glad Ethernet is not stuck with such a useless "feature". It would be trivial for someone to write up an "Ethernet EEK" or "IPv4 ND" draft and submit it to their favorite router vendors for implementation. If nobody has done so, it's obviously not that important. S
