Hi, I've configured ERC's in HA.I just want to understand the function of IP showing at eth4 interface in the attached screenshot. where -
eth0 - mgmt IP
eth1 - shared IP
eth5 - heartbeat IP
what is eth4 IP for ? on secondary rc eth4 IP' is - 172.31.255.3. Also is there any reason for this particular mask - 255.255.255.128 or its just like that.
