RIP is not just the most advanced routing protocol on the CCNA exam, but that means it is easy to overlook some of the important facts you must remember in order to pass the exam! Listed here are just a couple of these facts, to help you review for the assessment!
RIPs default behavior is to deliver 1 updates to version, but to accept equally version 2 and 1 routing updates.
R2( config )#router split
R2( config-router )#net 172.16.0.0
R2( config-router )#^Z
R2#show ip standards
Routing Protocol is "rip"
Delivering updates every 30 seconds, next due in 6 seconds
Invalid after 180 seconds, hold down 180, flushed after 240
Outgoing update filter list for several interfaces is
Incoming update filter list for many interfaces is
Redistributing: grab
Standard 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. To disable this behavior, work no auto-summary underneath the RIP process.
R1#conf t
R1( config )#router split
R1( config-router )#version 2
R1( config-router )#no auto-summary
That you don't specify a mask or wildcard mask when making RIP just the classful network, even if youre running RIP v2.
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z. Learn new resources on this affiliated article by clicking dubli review.

Debug ip address rip shows the routing updates and measurements while the adverts are directed and requested. To see this in action without waiting for another regularly scheduled update, work clear ip route *.
R1#debug ip address grab
RIP protocol debugging is on
R1#clear internet protocol address option *
01:16:54: RIP: delivering v1 update to 255.255.255.255 via Loopback1 (1.1.1.1)
01:16:54: network 2.0.0.0, metric 2
01:16:54: network 3.0.0.0, full 2
01:16:54: community 172.16.0.0, metric 1
01:16:54: network 10.0.0.0, metric 2
01:16:54: RIP: sending v1 update to 255.255.255.255 via Serial0 (172.16.123.1)
01:16:54: subnet 172.16.123.0, metric 1
01:16:54: system 1.0.0.0, metric 1

01:16:54: community 3.0.0.0, metric 2
01:16:54: network 10.0.0.0, full 2
To see only the routes identified by a routing protocol, work show ip address route followed by the title of the protocol:
R1#show internet protocol address way split
Dtc 2.0.0.0/8 [120/1] via 172.16.123.2, 00:00:26, Serial0
R 3.0.0.0/8 [120/1] via 172.16.13.2, 00:00:09, Serial1
[120/1] via 172.16.123.3, 00:00:09, Serial0
Dtc 10.0.0.0/8 [120/1] via 172.16.13.2, 00:00:09, Serial1
[120/1] via 172.16.123.3, 00:00:09, Serial0
[120/1] via 172.16.123.2, 00:00:26, Serial0
And do not forget - to turn off all presently running debugs, work undebug all.
R1#undebug all
All possible debugging has been turned off
As it pertains to the CCNA exam don't overlook RIP and IGRP. EIGRP and ospf are more complex to manage, but you need to understand to be able to pass the CCNA how distance vector protocols work!. If you are interested in data, you will likely fancy to learn about mlm.
