RIP isnt just the most complex routing protocol on the CCNA exam, but that means it is easy to ignore a number of the important details you must bear in mind so as to pass the exam! That will help you review for the assessment, here are just a couple of those facts! RIPs default behavior is always to send version 1 updates, but to accept both version 2 and 1 routing updates. For supplementary information, consider having a peep at: [http://perrybelcher.blog.co.uk/2014/02/22/how-perry-belcher-can-help-you-out-with-internet-advertising-17805067/ perry belcher article]. R2 config #router rip R2 config-router #net 172.16.0.0 R2 config-router #^Z R2#show internet protocol address methods Routing Protocol is rip Sending updates every 30 seconds, next due in 6 seconds Invalid after 180 seconds, maintain down 180, flushed after 240 Outgoing update filter list for several interfaces is Incoming update filter list for all interfaces is Redistributing: split Default version control: deliver version 1, receive any version Interface Send Recv Key-chain Serial0 1 1 2 By default, RIP v2 autosummarizes routing updates sent across classful community boundaries. For alternative viewpoints, please look at: [http://perry-belcher.webs.com/ find perry belcher]. To eliminate this behavior, run no auto-summary under the RIP process. R1#conf t R1 config #router split R1 config-router #version 2 R1 config-router #no auto-summary You may not specify a mask or wildcard mask when configuring RIP just the classful network, even though youre running RIP v2. R1#conf t Enter configuration commands, one per line. End with CNTL/Z. R1 config #router tear R1 config-router #version 2 R1 config-router #no auto-summary R1 config-router #network 172.10.0.0?? Debug ip rip displays the routing updates and metrics whilst the ads are sent and required. To see this doing his thing without looking forward to another regularly scheduled upgrade, work clear ip route *.

R1#undebug all All possible debugging has been turned off In regards to the CCNA exam dont overlook RIP and IGRP.

EIGRP and ospf tend to be more complex to manage, nevertheless, you need to understand how distance vector protocols work to be able to pass the CCNA!.
