4.3.4 Routing Table
Route Management > Routing Table > Routing Table page is used to display all routes that can be accessed via local network
interfaces, through static routes, or through a dynamically learned route. If route information is available through more than one
of these methods, the priority for route selection is local, static, and then dynamic (except when the distance parameter of a
dynamic route is set to a value that makes its priority exceed that of a static route). Also note that the route for local interface is
not enabled (i.e., listed in the routing table) unless there is at least one active link connected to that interface.
◆VLAN–VLAN identifier (i.e., configured as a valid IP subnet).
◆Destination IP Address– IP address of the destination network, subnetwork, or host. Note that the address 0.0.0.0 indicates
the default gateway for this router.
◆Net Mask / Prefix Length–Network mask for the associated IP subnet. This mask identifies the host address bits used for
routing to specific subnets.
◆Next Hop–The IP address of the next hop (or gateway) in this route.
◆Metric–Cost for this interface.
◆Protocol–The protocol which generated this route information. (Options: Local, Static, RIP, OSPF, Others)
Route Management > Routing Table > Static Routes page is used to enter static routes in the routing table. Static routes may be
required to access network segments where dynamic routing is not supported, or can be set to force the use of a specific route
to a subnet, rather than using dynamic routing. Static routes do not automatically change in response to changes in network
topology, so you should only configure a small number of stable routes to ensure network accessibility.
◆Destination IP Address – IP address of the destination network, subnetwork, or host.
◆Net Mask / Prefix Length–Network mask for the associated IP subnet. This mask identifies the host address bits used for
routing to specific subnets.
◆Next Hop–IP address of the next router hop used for this route.
◆Distance–An administrative distance indicating that this route can be overridden by dynamic routing information if the
distance of the dynamic route is less than that configured for the static route. Note that the default administrative distances used
