Loopback Address
The IPv6 loopback address is a link-local unicast address that enables a device
to send traffic to itself for self-testing purposes. The loopback address does
not have a physical interface assignment. If an IPv6 packet destined for the
loopback address is received on a switch interface, it must be dropped. The
IPv6 loopback address is never used as the source IPv6 address for any packet
that is sent out of a device, and the switch drops any traffic it receives with a
loopback address destination. An example use case is:
ProCurve# ping6 ::1
0000:0000:0000:0000:0000:0000:0000:0001 is alive, time = 1 ms
