Use the 'ip' utility...

#ip -f inet6 neigh
fe80::206:5bff:fefc:85f2 dev eth0 lladdr 00:06:5b:fc:85:f2 REACHABLE
fe80::200:1cff:fe00:ef67 dev eth0 lladdr 00:00:1c:00:ef:67 REACHABLE
fe80::211:bbff:fe88:b240 dev eth0 lladdr 00:11:bb:88:b2:40 router REACHABLE
fe80::290:27ff:fe94:dc5f dev eth0 lladdr 00:90:27:94:dc:5f REACHABLE
fe80::2a0:24ff:fe51:8b57 dev eth0 lladdr 00:a0:24:51:8b:57 REACHABLE


without '-f inet6' it lists both v6 neighbour cache, and v4 arptable.

#ip neigh
fe80::206:5bff:fefc:85f2 dev eth0 lladdr 00:06:5b:fc:85:f2 REACHABLE
fe80::200:1cff:fe00:ef67 dev eth0 lladdr 00:00:1c:00:ef:67 REACHABLE
