Hoi,
I think the crash is not our good way to demonstrate your config error, but
you should consider creating the GENEVE tunnel in "l3-mode" if you want to
use it as an L3 interface - by default the tunnel will be an L2 device (and
as such, should not be able to receive an IP address).
vpp# create geneve tunnel ?
create geneve tunnel create geneve tunnel local
<local-vtep-addr> {remote <remote-vtep-addr>|group <mcast-vtep-addr>
<intf-name>} vni <nn> [encap-vrf-id <nn>] [decap-next [l2|node <name>]]
[l3-mode] [del]
groet,
Pim
