We are having an issue with two Mikrotik CCR v6.33, where we cannot pass LLDP across a bridge. To test the functionality we setup one port per router bridged with an EOIP tunnel which connects the two routers with software 6.x (all versions seem affected in 6), plug a cisco 2960 into both sides, then test LLDP across the bridge, it doesn’t pass. I can see everything else, nothing else that I can tell is being blocked. If I plug the cisco devices into each other LLDP passes fine. If I do this same test with the 5.x software it works fine. The ultimate goal is to bridge an EOIP tunnel and a port, to build a transparent Link for our customer. All other traffic seems to pass. MTU Ono tunnel, bridge and interfaces is set to 1526, that the customer is able to transport full vlan informations.
Any suggestions ?
