I've got some further information. If I look for a specific address, it seems to work: root@...e0-0-0-5-0-11-1:/root> ip neigh show 172.24.136.0 172.24.136.0 dev bond0 lladdr 00:c0:8b:07:b3:7e REACHABLE In the above scenario, the arp cache lists the device as reachable via bond0. If I search the arp cache to see whether the address is reachable from one of bond0's slave devices, should it come back positive or negative?
