Cannot add tunnel mode gre multipoint line to dmvpn tunnel confi

Hi Jomo,

Did you (mis)configured tunnel destination earlier that you removed later?. I understand you tried deleting the tunnel and reconfigured to hit the same issue.

Can you try with a different tunnel number?.

What box and version is this?.

Hello Jomo,

use a different tunnel number, the router is remembering the old configuration of this tunnel interface, including the tunnel destination command that is not compatible with tunnel mode gre multipoint.

if you really want to reuse tunnel 0 you should:

delete the interface configuration

reload the router

then configure again the tunnel 0 interface

Hope to help
