Description
Enables aggregation of subnet information on
interfaces configured to send RIP v2 or RIP
v2-compatible traffic. The switch summarizes
subnet routes to the nearest class network
route. The following rules apply when using
RIP aggregation:
• Subnet routes are aggregated to the
nearest class network route when crossing
a class boundary.
• Within a class boundary, no routes are
aggregated.
• If aggregation is enabled, the behavior is
the same as in RIP v1.
• If aggregation is disabled, subnet routes are
never aggregated, even when crossing a
class boundary.
The default setting is disabled.
Enables RIP to redistribute routes from other
routing functions. Specify one of the following:
• static—Static routes
• direct—Interface routes (only interfaces
that have IP forwarding enabled are
exported)
• ospf—All OSPF routes
• ospf-intra—OSPF intra-area routes
• ospf-inter—OSPF inter-area routes
• ospf-extern1—OSPF AS-external route
type 1
• ospf-extern2—OSPF AS-external route
type 2
The metric range is 0–15. If set to 0, RIP
uses the route metric obtained from the route
origin.
Configures a default route to be advertised by
RIP if no other default route is advertised. If
always is specified, RIP always advertises the
default route to its neighbors. If always is not
specified, RIP adds a default route if there is a
reachable default route in the route table.
Enables the split horizon with poison-reverse
algorithm for RIP. The default setting is
enabled. If you enable poison reverse and split
horizon, poison reverse takes precedence.
Enables the split horizon algorithm for RIP.
Default setting is enabled.
Enables triggered updates. Triggered updates
are a mechanism for immediately notifying a
router's neighbors when the router adds or
deletes routes, or changes the metric of a
route. The default setting is enabled.
