RIP Authentication: The two versions of the Routing Information Protocol are RIPv1 and RIPv2, these two protocols are used for sub-netting and two are not supported authentication and RIPv2 only supports the authentication process. RIPv2 will be mainly used for the authentication process for sending, and receiving the data packets, send only the authenticated data only and receiving time first check that if the received data is authenticated or not. It will be secure and it allows hash-based authentication. The main advantage of the RIPv2 is it will be configuring with the same keys only.

In RIPv2 authentication, the time RIP will gain a configuring a key chain in both sending and receiving routers and it will check the authentications. The main concept of the keychain in the routing protocol and the authentication of the key chain in the routing protocol will be very familiar with the key chain.

The main function of the authentication key chain is to store a different number of different keys for all the authentication process. The important feature of the authentication key chain and it will be authenticated periodically. All key has index value and a string value.

The password of the key can be associated with the key-string value. Only the authenticated key can be used only. A valid key is used for the authentication process and the key is mentioned as every time it is life-time and so it is called sending and receiving the life-time key values.

A very important feature is to all the routers are to be running in the RIPv2 network and it will date and time settings will be the same in RIPv2 and it will properly work. The important disadvantage of this is configuration is very difficult for the same date and time settings. It will get from the time-synchronization protocol that is called Network Time Protocol (NTP). RIPv2 running with a different router from a Network and synchronize with all date and time settings is called Network Time Protocol (NTP)

In RIPv2 two methods of checking for the authentication process that is plain text authentication and the message digest authentication. The plain text method is not secure compare to message digest authentication. The password of the protocol in the case of plain text authentication it will be unencrypted. RIP authentication interface can be enabled only in sending and receiving time of the packets.

Steps for configuration:

  • First, enable the Router1
  • Firstly enable the Route1 and the commands are listed below
