Changing single path NIC to a teamed connection in same subnet
Dear all,
I have a remote CentOS7 server that has two network cards. Each card has four ports and port one of card one was defined with the IP address assigned to the server. So far, so good and it's been working for over a year. We have now got cables sorted out so there are four paths available (two from each card, via two switches) to give us resilience. After that, I have built a logical teamed device with the three new paths and it's all working just fine until I try to turn off the old un-teamed/single path eno1. I think it's all down to routing and I'm stuck.
Output from ip add show (removed unused ports for clarity):-
All seems well and I have changed the DNS to refer to the new IP address for the team0 device. I can SSH to the new IP address and verify with netstat that I am connected to the new IP. Output from netstat -nr and route -n:-
If I try to disable eno1 I get no network response until I turn it back on again via the console. It's the same it I delete the default route with route delete default gw 10.102.16.254 dev eno1
I just don't get it. There appears (to me) to be a valid route from device team0 so what am I missing?
I do see this oddity though:-
For completeness, my server reports the below:-
After I retire eno1 as a discreet connection, it will be added into the team to give the proper resilience.
I am quite expecting to be shown that I am a fool. I'd prefer that than being left hanging.
I have an OpenBSD 3.7 firewall with five network interfaces on it, one of which is connected to the Internet. I'd like to use the remaining four interfaces as a network switch for a single internal subnet. The main problem I have is that the DHCP daemon doesn't like multiple interfaces matching...

Hello Admins,
My ask is how can I add two different subnet IPs to same box with two different gateways?
