Configuration of MD5 authentication is a multistep process. You must first define a keychain
that contains attributes such as the password to be used to authenticate the connection and
the lifetime of the keychain for both sending and receiving, as demonstrated in Example 3-
106.
Example 3-106. Configuring a Keychain

Congo(config)# key chain nexus
Congo(config-keychain)# key 1
Congo(config-keychain-key)# key-string nexus
The next step is to enable authentication under the HSRP process, as illustrated in Example
3-107, and reference the keychain created in the previous step.

Enter configuration commands, one per line. End with
CNTL/Z.
Congo(config)# int vlan 100
Congo(config-if)# hsrp 100
Congo(config-if-hsrp)# authentication md5 key-chain nexus
You can verify that the MD5 authentication is in place from the output of the show hsrp
command, as demonstrated in Example 3-108.
