RIP isn’t meet the most Byzantine routing prescript on the CCNA exam, but that makes it cushy to lie whatever of the essential info you staleness ready in nous in meet to transfer the exam! To support you analyse for the exam, here are meet a some of those details!

RIP’s choice activity is to beam edition 1 updates, but to accept both edition 1 and 2 routing updates.

R2(config)#router rip

R2(config-router)#net 172.16.0.0

R2(config-router)#^Z

R2#show ip protocols

Routing Protocol is “rip”

Sending updates every 30 seconds, incoming cod in 6 seconds

Invalid after 180 seconds, stop downbound 180, healthy after 240

Outgoing update separate itemize for every interfaces is

Incoming update separate itemize for every interfaces is

Redistributing: rip

Default edition control: beam edition 1, obtain some version

Interface Send Recv Key-chain

Serial0 1 1 2

By default, RIP v2 autosummarizes routing updates dispatched crossways classful meshwork boundaries. To alter this behavior, separate no auto-summary low the RIP process.

R1#conf t

R1(config)#router rip

R1(config-router)#version 2

R1(config-router)#no auto-summary

You do not take a subnet cover or wildcard cover when configuring RIP - meet the classful network, modify if you’re streaming RIP v2.

R1#conf t

Enter plan commands, digit per line. End with CNTL/Z.

R1(config)#router rip

R1(config-router)#version 2

R1(config-router)#no auto-summary

R1(config-router)#network 172.10.0.0 ?

Debug ip countercurrent displays the routing updates and poetics as the advertisements are dispatched and requested. To wager this in state without inactivity for the incoming regularly regular update, separate country ip line *.

R1#debug ip rip

RIP prescript debugging is on

R1#clear ip line *

01:16:54: RIP: sending v1 update to 255.255.255.255 via Loopback1 (1.1.1.1)

01:16:54: meshwork 2.0.0.0, amount 2

01:16:54: meshwork 3.0.0.0, amount 2

01:16:54: meshwork 172.16.0.0, amount 1

01:16:54: meshwork 10.0.0.0, amount 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, amount 1

01:16:54: meshwork 1.0.0.0, amount 1

01:16:54: meshwork 2.0.0.0, amount 2

01:16:54: meshwork 3.0.0.0, amount 2

01:16:54: meshwork 10.0.0.0, amount 2

To wager exclusive the routes unconcealed by a routing protocol, separate exhibit ip line followed by the think of the protocol:

R1#show ip line rip

R 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

R 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 don’t block - to invoke soured every currently streaming debugs, separate undebug all.

R1#undebug all

All doable debugging has been overturned off

Don’t lie RIP and IGRP when it comes to the CCNA exam. OSPF and EIGRP are more Byzantine to configure, but you requirement to see how indifference agent protocols impact in meet to transfer the CCNA!

Once you intend your CCNA and CCNP, you can’t meet rest on your accomplishment. You’ve got to move to think and add to your power ordered - and then establish to Cisco you’ve been doing meet that by recertifying.

Recertification sounds same a pain, but it’s actually digit of the prizewinning things to ever hap to machine certification, and it helps your occupation as well. One hole some LAN and WAN organisation start into is that they modify to ready up with changes in technology, and if they hap to be ordered soured or poverty to modify jobs, they’re unable to because they didn’t ready their power ordered up.

Cisco’s recertification policies secure that if you poverty to ready your CCNA, CCNP, or digit of the added priceless Cisco certifications, you’ve got to verify a recertification exam.

As of Nov 2005, to recertify as a CCNA, you requirement to transfer either the underway CCNA exam, ICND exam, or some 642 professed take or Cisco Qualified Specialist exam. (This does not allow Sales Specialist exams.) Passing a CCIE cursive fittingness communicating also recertifies you as a CCNA. CCNAs are legal for threesome years.

For the CCNP, you requirement to transfer the 642-891 Composite exam, a CCIE cursive fittingness exam, or BOTH the BSCI and BCMSN exams (642-801 and 642-811, respectively.) CCNP certifications are legal for threesome years.

As you crapper see, you’ve got quite a some options either way. The digit artist nonachievement you staleness not attain is inactivity likewise daylong to begin preparing for the exams, and provide yourself a lowercase discrepancy meet in housing you don’t recertify the prototypal instance around. Once the deadline passes, your authorisation is gone, and in the housing of the CCNP that effectuation attractive every the exams again.

As a professional, it’s your domain to ready up with changes in the Cisco authorisation world, and this includes changes in the recertification program. Make a saucer of temporary the “Learning And Events” country of Cisco’s website regularly to countenance for changes in the authorisation program. And patch you’re there, you meet strength wager added cert that catches your eye!

Configuring RIPv2 and EIGRP marker with key chains crapper be hard at first, and the structure isn’t meet cushy to remember. But for BSCI and CCNP communicating success, we’ve got to be healthy to action this task.

In a preceding tutorial, we saw how to configure RIPv2 boat authentication, with both clear-text and MD5 marker schemes. EIGRP marker is such the same, and has the book and MD5 marker options as well. But EIGRP existence EIGRP, the bidding meet has to be a lowercase more detailed!

As with RIPv2, the marker fashion staleness be united upon by the EIGRP neighbors. If digit router’s programme is organized for MD5 marker and the far router’s programme is organized for book authentication, the nearness module change modify if the digit interfaces in discourse are organized to ingest the aforementioned password.

We’ll today configure unification marker on the nearness over an Ethernet segment. Below, you’ll wager how to configure a key concern titled EIGRP on both routers, ingest key sort 1, and ingest the key-string BSCI. Run exhibit key concern on a router to wager every key chains.

R2(config)#key concern EIGRP

R2(config-keychain)#key 1

R2(config-keychain-key)#key-string BSCI

R2#show key chain

Key-chain EIGRP:

key 1 — book “BSCI”

accept period (always valid) - (always valid) [valid now]

send period (always valid) - (always valid) [valid now]

R3(config)#key concern EIGRP

R3(config-keychain)#key 1

R3(config-keychain-key)#key-string BSCI

R3#show key chain

Key-chain EIGRP:

key 1 — book “BSCI”

accept period (always valid) - (always valid) [valid now]

send period (always valid) - (always valid) [valid now]

The EIGRP bidding to administer the key concern is a taste of a discompose to remember, because the prescript and AS sort is identified in the region of the command, not the beginning. Also state that digit commands are necessary - digit to study the key chain, added to delimitate the marker fashion in use.

R2(config)#interface ethernet0

R2(config-if)#ip marker key-chain eigrp 100 EIGRP

R2(config-if)#ip marker fashion eigrp 100 md5

5d07h: %DUAL-5-NBRCHANGE: IP-EIGRP 100: Neighbor 172.12.23.3 (Ethernet0) is down: keychain changed

R3(config)#interface ethernet0

R3(config-if)#ip marker key-chain eigrp 100 EIGRP

R3(config-if)#ip marker fashion eigrp 100 md5

5d07h: %DUAL-5-NBRCHANGE: IP-EIGRP 100: Neighbor 172.12.23.2 (Ethernet0) is up:

As with RIPv2, the existing nearness was torn downbound when digit lateral was organized with authentication. If the key concern is aright circumscribed and practical on both sides, the nearness module become backwards up. Always separate exhibit ip eigrp edge to attain trusty the nearness is present. Learn the info of EIGRP key chains by configuring them on your bag work equipment, and you’ll be more than primed for BSCI communicating success!
