III-5-7. Static Routing
Static routing is a method of configuring path selection of routers,
characterized by the absence of communication between routers regarding
the current topology of the network. The opposite of static routing is dynamic
routing, sometimes also referred to as adaptive routing.
You can configure static routing and manually add routes to the routing table
on this page.
Check off to enable/disable and the router will not
answer ping requests from the Internet.
