My connection is lost when I add an interface to a bridge. Here I want to add eno3 to bridge kvbr0:
sudo ip link add name kvbr0 type bridge
sudo ip addr del 10.120.224.70/23 dev eno3
sudo ip addr add 10.120.224.70/23 brd + dev kvbr0
sudo ip link set eno3 master br0
sudo ip link set kvbr0 up
10.120.224.70 is the IP address of eno3. After running the above, I can no longer ssh into this address.
This is what I see for the interfaces:
kvbr0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1316

kvbr0 has the previous IP settings from eno3.
The server is running Rocky9 with kernel 6.1.
I tried the above commands on a VM machine running Ubuntu, and I can ssh into the IP address. Is there anything I should be aware of on the server that would prevent network connectivity after running those commands?
The server has an Intel I350 NIC. The product brief says the adapter is "bridgeless." Could this be causing the problem I'm seeing?
There wasn't a default route:
I realized this was the issue when I observed I could ping the server from a machine on the local network but not from an outside machine.
