RIP isn't precisely the most complicated routing protocol on the CCNA exam, but that tends to make it easy to overlook some of the important information you must keep in mind in order to pass the exam! To assist you evaluation for the exam, here are just a few of those particulars!
RIPs default behavior is to send version 1 updates, but to accept both version 1 and two routing updates.
R2(config)#router rip
R2(config-router)#net 172.16..
R2(config-router)#^Z
R2#show ip protocols
Routing Protocol is "rip"
Sending updates every 30 seconds, next due in 6 seconds
Invalid soon after 180 seconds, hold down 180, flushed after 240
Outgoing update filter list for all interfaces is
Incoming update filter list for all interfaces is
Redistributing: rip
Default version control: send version 1, receive any version
Interface Send Recv Crucial-chain
Serial0 1 1 2
By default, RIP v2 autosummarizes routing updates sent across classful network boundaries. To disable this behavior, run no auto-summary beneath the RIP approach.
R1#conf t
R1(config)#router rip
R1(config-router)#version 2
R1(config-router)#no auto-summary
You do not specify a subnet mask or wildcard mask when configuring RIP just the classful network, even if youre running RIP v2.
R1#conf t
Enter configuration commands, one particular per line. Finish with CNTL/Z.
R1(config)#router rip
R1(config-router)#version 2
R1(config-router)#no auto-summary
R1(config-router)#network 172.ten.. ?
Debug ip rip displays the routing updates and metrics as the ads are sent and requested. To see this in action without having waiting for the subsequent regularly scheduled update, run clear ip route *.
R1#debug ip rip
RIP protocol debugging is on
R1#clear ip route *
01:16:54: RIP: sending v1 update to 255.255.255.255 through Loopback1 (1.1.1.1)
01:16:54: network two..., metric two
01:16:54: network three..., metric two
01:16:54: network 172.16.., metric 1
01:16:54: network 10..., 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., metric 1
01:16:54: network 1..., metric 1
01:16:54: network 2..., metric two
01:16:54: network 3..., metric 2
01:16:54: network ten..., metric 2
To see only the routes discovered by a routing protocol, run show ip route followed by the name of the protocol:
R1#show ip route rip
R two.../eight [120/1] via 172.16.123.2, 00:00:26, Serial0
R three.../eight [120/1] by means of 172.16.13.2, 00:00:09, Serial1
[120/1] via 172.16.123.three, 00:00:09, Serial0
R 10.../eight [120/1] by means of 172.16.13.two, 00:00:09, Serial1
[120/1] by way of 172.16.123.3, 00:00:09, Serial0
[120/1] by means of 172.16.123.2, 00:00:26, Serial0
And do not neglect - to turn off all at the moment running debugs, run undebug all.
R1#undebug all
All possible debugging has been turned off
Don't overlook RIP and IGRP when it comes to the CCNA exam. OSPF and EIGRP are more complicated to configure, but you require to recognize how distance vector protocols operate in order to pass the CCNA! empower network
