Hi,
I have configured neighbor discovery on a bridge interface, and am now seeing multiple neighbors per physical interface, which does not seem useful.
After an initial investigation, having the CDP and MNDP protocols enabled seems to exhibit this behavior. If I enable only LLDP, and make sure to have LLDP enabled in the other end, it seems to only discover the directly connected device, as I would expect. It is my understanding that this is the intended behavior, and I thought that at least CDP is supposed to mimic LLDP in that regard. Not sure about MNDP.
I guess I can use only LLDP if that is necessary. Would like to know what the intended behavior is.
This is on 6.48.6. I have witnessed the same behavior on at least some slightly older versions, too.
