Bridge strangness, have same IP twice on bridge and one on main nic.
Hi. I've been setting up a bridge for KNM VM. I first set it up on a test machine and had the IP on the bridge only. When I put it into production I have the IP twice on the bridge (/22 and /32) and it is also on the main NIC. This makes no sense to me. Been scratching my head for a week. Also been having problems with the network connection from the VM so want to see if this is why.
So ip addr
2: enp7s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master br0 state UP group default qlen 1000
link/ether 2c:4d:54:43:92:df brd ff:ff:ff:ff:ff:ff
inet xxx.171.204.107/22 brd xxx.171.207.255 scope global enp7s0
valid_lft forever preferred_lft forever
inet6 fe80::2e4d:54ff:fe43:92df/64 scope link
valid_lft forever preferred_lft forever
4: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether 2c:4d:54:43:92:df brd ff:ff:ff:ff:ff:ff
inet xxx.171.204.107/32 brd xxx.171.204.107 scope global br0
valid_lft forever preferred_lft forever
inet xxx.171.204.107/22 brd xxx.171.207.255 scope global br0
valid_lft forever preferred_lft forever
inet6 fe80::2e4d:54ff:fe43:92df/64 scope link
valid_lft forever preferred_lft forever
(will pst whole 'ip addr' below)
Main NIC config

#HWADDR=2c:4d:54:43:92:df
