EIGRP Neighbor Authentication


{In EIGRP we create Key Chain which we specify the Password to Authenticate the other Routers}
{After We Implement the Key chain in Router Interfaces}
{We use MD5 (128 bits) Authentication}

Ø  ROUTER1(config)#key chain DEMO     {Demo:- key chain Name (any)
Ø  ROUTER1(config-keychain)#key 1          {1: key no {any} But Same in all routers}
Ø  ROUTER1(config-keychain-key)#key-string cisco       {cisco :- Password same in all routers}
Ø  ROUTER1(config-keychain-key)#exit

{Now Implement the Key Chain in interfaces of routers}
Ø  ROUTER1(config-if)#interface serial 0/1
Ø  ROUTER1(config-if)#ip authentication key-chain eigrp 10 DEMO
Ø  ROUTER1(config-if)#ip authentication mode eigrp 10 md5
Ø  ROUTER1(config-if)#exit

Ø  ROUTER1(config)#interface fastEthernet 0/1
Ø  ROUTER1(config-if)#ip authentication mode eigrp 10 md5
Ø  ROUTER1(config-if)# ip authentication key-chain eigrp 10 DEMO

Ø  ROUTER1(config)#interface f1/0
Ø  ROUTER1(config-if)# ip authentication mode eigrp 10 md5
Ø  ROUTER1(config-if)# ip authentication key-chain eigrp 10 DEMO
Ø  ROUTER1(config-if)#exit

Ø  ROUTER2(config)#key chain DEMO      {Demo:- key chain Name (any)
Ø  ROUTER2(config-keychain)# key 1     {1: key no {any} But Same in all routers}
Ø  ROUTER2(config-keychain-key)#  key-string cisco       {cisco :- Password same in all routers}
Ø  ROUTER2(config-keychain-key)#exit

{Now Implement the Key Chain in interfaces of routers}
Ø  ROUTER2(config)#interface serial0/1
Ø  ROUTER2(config-if)#ip authentication mode eigrp 10 md5
Ø  ROUTER2(config-if)# ip authentication key-chain eigrp 10 DEMO
Ø  ROUTER2(config-if)#exit

Ø  ROUTER2(config)#interface f1/0
Ø  ROUTER2(config-if)#ip authentication mode eigrp 10 md5
Ø  ROUTER2(config-if)# ip authentication key-chain eigrp 10 DEMO
Ø  ROUTER2(config-if)#exit

Ø  ROUTER2(config)#interface f0/1
Ø  ROUTER2(config-if)#ip authentication mode eigrp 10 md5
Ø  ROUTER2(config-if)# ip authentication key-chain eigrp 10 DEMO
Ø  ROUTER2(config-if)#exit

Ø  ROUTER3(config)#key chain DEMO         {Demo:- key chain Name (any)
Ø  ROUTER3(config-keychain)# key 1         {1: key no {any} But Same in all
Ø  ROUTER3(config-keychain-key)#  key-string cisco     {cisco :- Password same in all routers}
Ø  ROUTER3(config-keychain-key)#exit

{Now Implement the Key Chain in interfaces of routers}
Ø  ROUTER3(config)#interface fastEthernet 0/0

Ø  ROUTER3(config-if)# ip authentication key-chain eigrp 10 DEMO
Ø  ROUTER3(config-if)#exit

Ø  ROUTER3(config)#interface fastEthernet 0/1
Ø  ROUTER3(config-if)#ip authentication mode eigrp 10 md5
Ø  ROUTER3(config-if)# ip authentication key-chain eigrp 10 DEMO
