When you earned your CCNA, you believed you learned anything there is to know about RIP. Close, but not rather! There are some extra details you need to know to pass the BSCI exam and get one particular step closer to the CCNP exam, and one particular of these requires RIP update packet authentication.

You are familiar with some positive aspects of utilizing RIPv2 over RIPv1, support for VLSM chief amongst them. But one advantage that you're not introduced to in your CCNA scientific studies is the potential to configure routing update packet authentication.

You have two possibilities, clear text and MD5. This tasteful rabbit vibrator article directory has a few cogent aids for the inner workings of it. Clear text is just that - a clear text password that is visible by any person who can pick a packet off the wire. If you are going to go to the difficulty of configuring update authentication, you ought to use MD5. The MD stands for "Message Digest", and this is the algorithm that generates the hash value for the password that will be contained in the update packets.

Not only must the routers agree on the password, they should agree on the authentication approach. To research more, you are able to check-out: mini vibrator.

If one router sends an MD5-hashed password to yet another router that is configured for clear-text authentication, the update will not be accepted. debug ip rip is a wonderful command for troubleshooting authenticated updates.

R1, R2, and R3 are operating RIP more than a frame relay cloud. Here is how RIP authentication would be configured on these three routers.

R1#conf t

R1(config)#essential chain RIP

< The key chain can have any name.>

R1(config-keychain)#essential 1

< Key chains can have multiple keys. Browse here at small vibrator to explore the meaning behind this view. Number them carefully when using multiples.>

R1(config-keychain-crucial)#crucial-string CISCO

< This is the text string the key will use for authentication.>

R1(config)#int s0
