4. Configuring Routing
The switch supports IP routing. Use the menus under the Routing tab to manage routing on
the system.
When a packet enters the switch, the destination MAC address is checked to see if it
matches any of the configured routing interfaces. If it does, then the switch searches the host
table for a matching destination IP address. If an entry is found, then the packet is routed to
the host. If there is no matching entry, then the switch performs a longest prefix match on the
destination IP address. If an entry is found, then the packet is routed to the next hop. If there
is no match, then the packet is routed to the next hop specified in the default route. If there is
no default route configured, then the packet is passed to the software to be handled
appropriately.
The routing table can have entries added statically by the administrator. The host table can
have entries added either statically by the administrator or dynamically via ARP.
