Similar to the IPv4 ping, use the IPv6 ping6 command in the EXEC mode.
ping6 {ip-address | hostname} [GigabitEthernet 0-3][packetsize packetsize] [pingcount pingcount]
No default behavior or values.
The IPv6 ping6 command sends an echo request packet to an address, then awaits a reply. The ping output can help you evaluate path-to-host reliability, delays over the path, and whether you can reach a host.
The IPv6 ping6 command is similar to the existing IPv4 ping command. The ping 6 command does not support the IPv4 ping fragmentation (df in IPv4) options, but it allows an optional specification of an interface. The interface option is primarily useful for pinning with link-local addresses that are interface-specific. The packetsize and pingcount options work the same as they do with the IPv4 command.
