We have a Frame Relay PVC , which is being used with Traffic Shaping to limit Traffic within our CIR Limit.
However still we receive some FECN, BECN notifications from the Provider's Frame Switch and dropped packets counter also increments occasionally.
Ideally i think that if we are within our CIR, we shouldn't be getting any BECN\FECN etc ?
However is there an acceptable percentage of BECN\FECN that i can compromise on ?
We actually use this PVC for Voice (however it is still considered a DATA PVC in provider's network) and that is why i have configured it to not to go above our CIR, so there are no packets eligible to be dropped.
Re: Acceptable % of BECN, FECN and Dropped Packets
Looking at the configs, they do look fine.
Be = 0, Bc = cir/100 for voice, cir = mincir.
Since you are using VOFR, there is no need for Frame-relay ip rtp header compression command, as Voice is sent as Framerelay frames, and not as IP packets.
RTP header compresion could have been used, if you were using VOIP over framrelay.
Check to see in your "show frame-relay pvc" and see if your Frame-relay traffic shaping is shown as ACTIVE or INACTIVE. Traffic shaping will be active, only when your router is subscribing over the CIR.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
