Corrections – I invite them.
1. Create the keys in the keychain.
R101(config)#key chain KEYCHAIN
R101(config-keychain)#key 1
R101(config-keychain-key)#key-str
R101(config-keychain-key)#key-string MYKEY
2. Enable authentication on an interface.
R101(config-if)#ip authentication mode eigrp 1 md5
3. Associate keychain with EIGRP.
ip authentication key-chain eigrp
