Hi there,
We've just upgraded to Firepowers (1120's) from ASA's and are trying, well have got working, route based VPN's.
The 'issue' I'm having is that when I use the GUI to create the VTI interface I get the enclosed error message.

"IPv6 Source Address should be mandatory"
But I'm not using v6, so the only way I can create the VTI is by CLI, this isn't an issue but I'm wondering if there is a bug with the ASDM or something that is creating this error message or is there a more global command statement that negates IPv6 ?
I'm running 9.16(3) ASA, with 7.16(1) ASDM.
Thanks for any replies.
