Information
The tunnel interface is inoperable without a valid tunnel destination address for the 
configured Tunnel mode.
To establish a logical tunnel to the particular destination address, use the 
destination address of the outer tunnel header. If you configure a tunnel interface 
or source address, the tunnel destination must be compatible.

which the tunnel borrows its address.

operationally down unless you also configure the tunnel IPv6 address.
