Routing concepts
The switch supports IP routing. When a packet enters the switch, the switch checks the
destination MAC address to determine if it matches any of the configured routing
interfaces. If it does, the switch searches the host table for a matching destination IP
address. If a matching entry is found, the packet is routed to the host. If no matching
entry is found, the switch performs a longest prefix match on the destination IP address.
If a matching entry is found, the packet is routed to the next hop. If no matching entry
is found, the packet is routed to the next hop that is specified in the default route. If no
default route exists, the packet is dropped.
Routing table, routes and route preferences
The routing table collects routes from multiple sources and list all routes: static routes,
local routes, dynamically added routes, and so on. Static routes are routes that you
manually add. The routing table can learn multiple routes to the same destination from
multiple sources, for example dynamically added routes through routing protocols.
Configure a route and display learned routes
You can add or change a route in the routing table and display the automatically learned
routes in the routing table.
