Lab Solution

Task 1
Configure RIP authentication between R1 and R3 using clear text method. Use key 1, and the password CISCO13.

R1 Configuration:
!
key chain RIP_CLEAR_TEXT
 key 1
   key-string CISCO13
!
interface Serial0/1
 ip address 10.1.13.1 255.255.255.0
 ip rip authentication key-chain RIP_CLEAR_TEXT
 serial restart-delay 0
!

R3 Configuration:
!
key chain RIP_CLEAR_TEXT
 key 1
   key-string CISCO13
!
interface Serial0/1
 ip address 10.1.13.3 255.255.255.0
 ip rip authentication key-chain RIP_CLEAR_TEXT
 serial restart-delay 0
!

Task 2
Configure RIP authentication between R2 and R3 using MD5 method. Use key 1, and the password CISCO23.

R2 Configuration:
!
key chain RIP_MD5
 key 1
   key-string CISCO23
!
interface Serial0/2
 ip address 10.1.23.2 255.255.255.0
 ip rip authentication mode md5
 ip rip authentication key-chain RIP_MD5
!

R3 Configuration:
!
key chain RIP_MD5
 key 1
   key-string CISCO23
!
interface Serial0/2
 ip address 10.1.23.3 255.255.255.0
 ip rip authentication mode md5
 ip rip authentication key-chain RIP_MD5
 serial restart-delay 0
!
