Okay, so I tested 4 open-source LLDP implementations yesterday [1-4]... while LLDP works fine over batman-adv, I didn't find it very useful. 1st, implementations [1-3] aren't very configurable, and [4], an implementation by Intel, is hard to configure and *huge* (stripped binary ~400KB). Most of the implementations don't support announcing IPv6 addresses (I'm not sure which anymore), although that isn't really an important feature for me, as I'd use it mostly to announce hostnames for the MAC addresses, but I consider software that only supports IPv4 as deprecated. Also, most of these projects seem to be dead for years. 2nd, I think without batman-adv specific extensions LLDP isn't very useful, as the LLDP daemon only cares about the bat0/bridge MAC addresses, and not the hardif MAC addresses which are visible in the vis. The softif MAC addresses are shown in the vis as TT records, of course, but as one can't really discern between the adresses of the node itself and those of other clients on the bridge, it's rather useless in my opinion.
