Do an "ip route" on both the source and destination nodes.

also do an "ip neigh" on both.

And an "ip link" on both.

Yes, that would be very helpful if Robert would supply that information.
Thanks for making that suggestion

Have to apologize. Cockpit error. The address should have been

192.168.1.211 instead of 192.168.1.112

From the host system

Well, the information below would seem to be incomplete since you probably have not tried to access 192.168.1.211. We do see FAILED for 192.168.1.112 since you've probably tried it and a host with that IP address doesn't exist.

You can see that for the IPv6 address of 2600:1702:4860:9dd0:210:75ff:fe28:5e30 the hwaddress of 00:10:75:28:5e:30 matches that of eth0 in the "ip link" results of the target system. That would indicate physical connectivity.

So, would you do these in order?

ip -4 add show
ping 192.168.1.211
traceroute -n 192.168.1.211
ip neigh

Tried the correct address as soon as my mind quit pl aying tricks on me then caught on that the second ipv6 address wanted the tag of the local device attached

 ip -4 add show
