 Password authentication. Simple password authentication is vulnerable for
passive attacks (sniffing) because broadcasting is used and the packet has a
password in an explicit form.
 Cryptographic authentication. Key is used while generation and check of
message-digest signatures. Digital signature is built based on MD5 algorithm.
As a secret key is never send over the network in a clear form, this gives a
protection from passive attacks.
By default, the router does not have any authentication (null-authentication).
Authentication can be configured individually for each interface using the
following commands in config-if mode:
1 Password authentication:
authentication mode text
authentication string LINE
where LINE - password, less than 16 symbols.
2 Cryptographic authentication:
authentication mode md5
authentication key-chain LINE
where LINE - name of the secret MD5 key
To configure the key which name is specified in LINE parameter use command in
config mode:
RIP(config)# key chain WORD
RIP(config-keychain)# key <0-2147483647>
RIP(config-keychain-key)# key-string LINE
where
WORD - key chain name
<0-2147483647> - key ID
LINE - secret md5 key
