• If Tunnel mode is ipv6ip (where ip address over tunnel interface is not possible).
To ping the unnumbered tunnels, the logical address route information must be
present at both the ends.
NOTE: The ipv6 unnumbered command can specify an interface name that
does not exist or does not have a configured IPv6 address. The tunnel
interface is not changed to operationally up until the logical ip address is
identified from the one of the address family.
