Usage Information
The ip unnumbered command fails in two conditions:
  • If the logical ip address is configured.
  • 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 ip 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 one of the address family.
