Lab 7. EIGRP – Authentication

Pada EIGRP terdapat fitur Authentication, fitur ini berfungsi untuk keamanan jaringan yang menggunakan Routing Protocol EIGRP, EIGRP hanya mendukung authentication dengan MD5.

 

-R1

Router(config)#key chain EIGRP

Router(config-keychain)#key 1

Router(config-keychain-key)#key-string CCNP

Router(config-keychain-key)#exit

 

Router(config-keychain)#int e0/0

Router(config-if)#ip authentication mode eigrp 10 md5

Router(config-if)#ip authentication key-chain eigrp 10 EIGRP

-R2

Router(config)#key chain EIGRP

Router(config-keychain)#key 1

Router(config-keychain-key)#key-string CCNP

Router(config-keychain-key)#exit

 

Router(config)#int e0/0

Router(config-if)#ip authentication mode eigrp 10 md5

Router(config-if)#ip authentication key-chain eigrp 10 EIGRP

 

 

 

Selanjutnya Verifikasi:

-R1

Router#debug eigrp packets

    (UPDATE, REQUEST, QUERY, REPLY, HELLO, UNKNOWN, PROBE, ACK, STUB, SIAQUERY, SIAREPLY)

EIGRP Packet debugging is on

Router#

*Aug  5 01:47:32.433: EIGRP: received packet with MD5 authentication, key id = 1

*Aug  5 01:47:32.433: EIGRP: Received HELLO on Et0/0 - paklen 60 nbr 12.12.12.2

*Aug  5 01:47:32.433:   AS 10, Flags 0x0:(NULL), Seq 0/0 interfaceQ 0/0 iidbQ un/rely 0/0 peerQ un/rely 0/0

*Aug  5 01:47:32.794: EIGRP: Sending HELLO on Et0/0 - paklen 60

*Aug  5 01:47:32.794:   AS 10, Flags 0x0:(NULL), Seq 0/0 interfaceQ 0/0 iidbQ un/rely 0/0

 

Maka sudah selesai!
