Hoi Stephan, Looking at your config, you have Gi2/6/0 which has a static to one another for 10.10.5/24 and 10.10.2/24 respectively 10.10.1/24 and 10.10.4/24. I assume any host in those 4 subnets will be able to reach each other (as the GENEVE tunnel is unrelated to it). Can you confirm? Then, I see this GENEVE tunnel between the two, with an inner of 10.10.3/24 so I would expect that 10.10.3.1 can reach 10.10.3.2 and vice versa. Can you confirm?
It's not clear to me what you mean with pinging from both sides of the tunnel, because there's nothing attached to them except .1 and .2 themselves. Can you clarify: 1) what IP address is trying to ping what other one, and 2) what was the resulting ARP request, and 3) on which interface was that seen? To avoid this becoming an XY-problem, can you clarify (without using VPP config statements), which topology you're trying to build?
