Specifying the IP addresses of servers
About server IP address
Server IP addresses can be those of the interfaces on a router in a VRRP group and those of the servers collaborating with MFF, such as a RADIUS server.
When the MFF device receives an ARP request from a server, the device searches IP-to-MAC address entries it has stored. Then the device replies with the requested MAC address to the server.
As a result, packets from a host to a server are forwarded by the gateway. However, packets from a server to a host are not forwarded by the gateway.
MFF does not check whether the IP address of a server is on the same network segment as that of a gateway. Instead, it checks whether the IP address of a server is all-zero or all-one. An all-zero or all-one server IP address is invalid.
Restrictions and guidelines
If the server's interface connecting to the MFF device uses secondary IP addresses to send ARP packets, include all these IP addresses in the server IP address list.
