Configuring MD5 authentication is a multistep process. You must first define a keychain that<br />

contains attributes like the password to be used to authenticate the connection <strong>and</strong> lifetime of<br />

the key chain for both sending <strong>and</strong> receiving, as demonstrated in Example 3-125.<br />

Example 3-125. Configuring a Keychain<br />

Congo(config)# key chain <strong>nexus</strong><br />

Congo(config-keychain)# key 1<br />

Congo(config-keychain-key)# key-string <strong>nexus</strong><br />

The next step is to enable authentication under the GLBP process, as demonstrated in<br />

Example 3-126, <strong>and</strong> reference the keychain created in Example 3-125.
