Preference metric used in a network topology where multi-homed hosts have access to
multiple routers. Router Preference helps a host to choose an appropriate router. There
are three preferences to choose from, such as High, Medium, or Low. The default
setting is High. Select the preference from the drop-down list.
Router Preference
The MTU is the size of the largest packet that can be sent over the network. It is used
in the router advertisement messages to ensure that all nodes on the network use the
same MTU value when the LAN MTU is not well-known. The default setting is 1500
bytes, which is the standard value for Ethernet networks. For PPPoE connections, the
standard is 1492 bytes. Unless your ISP requires a different setting, this setting should
not be changed. Enter a value between 1280 and 1500.
