Actually tunnel will comes up when the destination address u have given from
the command "tunnel destination x.x.x.x"
is reachable via IGP ... either static or dynamic and the tunnel will only
monitor it when the destination is not reachable
u will get a message "tunnel DOWN" ..... we are not concern about the
keepalive of the tunnel the main point is that the
destination should be reachable...... try removing destination from ur IGP
then see what happen after time-out.
