Synopsis: string
The authentication string.
Split horizon controls whether routes learned through an interface should be allowed to be
advertised back out that interface. By default RIP advertises all routes it knows about to
everyone, which makes it take a very long time for dropped links to age out of the network.
The split horizon prevents advertising those routes back out the same interface which helps
to control this problem. Some network topologies with rings of routers will still have some
issues with aging out dead routes even with split horizon enabled but they will still age out
faster. If fast network recovery is desired, use OSPF.
34.4. OSPF
Figure 34.9. OSPF Menu
The OSPF menu is accessible from the main menu under routing. The path to this menu is routing/
dynamic/ospf. The OSPF Area Distance form and the OSPF Configuration form appear on the same
screen as the OSPF menu.
