Lab 18: EIGRP Authentication

Let's configure EIGRP with authentication on R1 and R2:

key chain KC1
 key 1
   key-string PASSWORD

interface Serial0/0
 ip authentication mode eigrp 1 md5
 ip authentication key-chain eigrp 1 KC1

After the configuration, EIGRP neighborship is established:

R1#show ip eigrp neighbors
IP-EIGRP neighbors for process 1
H   Address                 Interface       Hold Uptime   SRTT   RTO  Q  Seq
                                            (sec)         (ms)       Cnt Num
