The following example of the show ip protocols command confirms that both versions are sent out that interface. This interface no longer sends and receives the same RIP versions as Dell Networking OS does globally (shown in bold). Dell#show ip protocols Routing Protocols is RIP Sending updates every 30 seconds, next due in 11 Invalid after 180 seconds, hold down 180, flushed after 240 Output delay 8 milliseconds between packets Automatic network summarization is in effect Outgoing filter for all interfaces is Incoming filter for all interfaces is Default redistribution metric is 1 Default version control: receive version 2, send version 2 Interface Recv Send FastEthernet 0/0 2 1 2 Routing for Networks: 10.0.0.0 Routing Information Sources: Gateway Distance Last Update Distance: (default is 120) Dell# Generating a Default Route Traffic is forwarded to the default route when the traffic's network is not explicitly listed in the routing table. Default routes are not enabled in RIP unless specified. Use the default-information originate command in ROUTER RIP mode to generate a default route into RIP. In Dell Networking OS, default routes received in RIP updates from other routes are advertised if you configure the defaultinformation originate command. • Specify the generation of a default route in RIP. ROUTER RIP mode default-information originate [always] [metric value] [route-map route-mapname] - always: Enter the keyword always to always generate a default route. - value The range is from 1 to 16. - route-map-name: The name of a configured route map. To confirm that the default route configuration is completed, use the show config command in ROUTER RIP mode. Summarize Routes Routes in the RIPv2 routing table are summarized by default, thus reducing the size of the routing table and improving routing efficiency in large networks. By default, the autosummary command in ROUTER RIP mode is enabled and summarizes RIP routes up to the classful network boundary. If you must perform routing between discontiguous subnets, disable automatic summarization. With automatic route summarization disabled, subnets are advertised. 772 Routing Information Protocol (RIP)
