NETGEAR 8800 Chassis Switch CLI Manual Syntax Description always cost tag Specifies to always advertise the default route. Specifies a cost metric. The range is 1 - 15. Specifies a tag number. Default Disabled. Usage Guidelines If always is specified, RIP always advertises the default route to its neighbors. If always is not specified, RIP advertises a default route only if a reachable default route is in the system route table. The default route advertisement is filtered using the out policy. The cost metric is inserted for all RIP-learned, static, and direct routes injected into RIP. The tag value is used only by special routing applications. Example The following command configures a default route to be advertised by RIP if there is a default route in the system routing table: enable rip originate-default cost 7 enable rip poisonreverse enable rip poisonreverse Description Enables poison reverse algorithm for RIP. Syntax Description This command has no arguments or variables. Default Enabled. Usage Guidelines Like split horizon, poison reverse is a scheme for eliminating the possibility of loops in the routed topology. In this case, a router advertises a route over the same interface that supplied the route, but the route uses a hop count of 16, defining it as unreachable. 966 | Chapter 21. RIP Commands
