Specifying the IP addresses of servers
You must specify the servers on the MFF device to ensure communication between the servers and clients.
When the MFF device receives an ARP request from a server, the MFF 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.
You can specify a server's IP address in manual MFF mode.
To specify the IP addresses of servers:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter VLAN view. | vlan vlan-id | N/A |
3. Specify the IP addresses of servers. | mac-forced-forwarding server server-ip&<1-10> | By default, no server IP address is specified. 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. |
