Good bye ARP, welcome ICMPv6

Today I was working on an IPv6 lab. I wanted discover the relation between an address MAC and an IP address. So, on the windows machine I execute the command 'arp -a'. It's a bad reflex, why ? ARP no longer exists in IPv6. The equivalent is now realized with ICMPv6. So to discover the correlation between MAC and IP address we have to use these commands:

• On a windows laptop:

C:\Users\Administrator>netsh interface ipv6 show neighbors 14

Interface 14: LAB

• On a Linux laptop (has to be validated):

ip -f inet6 neigh show

• On a Cisco router:

R2#show ipv6 neighbors
