Re: Ping in IPv6

As you know IPv6 does not support broadcast, but only multicast. As far as
I know you won't be able to get the same results in IPv6. You can do a ping
to all multicast hosts ff02::1 but you still have to specify an output
interface.

R1#ping ipv6 *FF02::1*
Output Interface: *gigabitethernet1/0*
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to FF02::1, timeout is 2 seconds:
Packet sent with a source address of
FE80::C800:2FFF:FE6C:1C%GigabitEthernet1/0

If you are trying to figure out if your layer 2 is working on the lab, it
still makes sense to do 255.255.255.255 as long as you're running
dual-stack.
