C H A P T E R 13 RIP and OSPF
239
enable rip aggregation Enables aggregation of subnet information on
interfaces configured to send RIP v2 or RIP v2-
compatible traffic. The 480T routing switch
summarizes subnet routes to the nearest class
network route. These 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.
enable rip export [static | direct | ospf | ospf-
intra | ospf-inter | ospf-extern1 | ospf-
extern2 | static | vip] cost <metric> {tag
<number>}
Enables RIP to redistribute routes from other
routing functions.
Specify:
•static—Static routes
•direct—Interface routes (only interfaces
with IP forwarding enabled are exported)
•ospf—All OSPF routes
•ospf-intra—OSPF intra-area routes
•ospf-inter—OSPF inter-area routes
•ospf-extern1—OSPF network-
unreachable route type 1
•ospf-extern2—OSPF network-
unreachable route type 2
•vip—Virtua l IP
The cost (metric) range is 0-15. If set to 0,
RIP uses the route metric from the route origin.
