which the tunnel borrows its address.

operationally down unless you also configure the tunnel IPv6 address.

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.
