Re: RE: OT - A puzzle for CCIE Students

One more efficient solution:

R1:
Router#sh run | s rip|chain|1/0
key chain R1
 key 2
   key-string cisco2
 key 3
   key-string cisco3
interface FastEthernet1/0
 ip address 10.1.1.1 255.255.255.0
 ip rip authentication key-chain R1
router rip
 version 2
 network 10.0.0.0
 no auto-summary

R2:
Router#sh run | s rip|chain|1/0
key chain R2
 key 2
   key-string cisco2
interface FastEthernet1/0
 ip address 10.1.1.2 255.255.255.0
 ip rip authentication key-chain R2
router rip
 version 2
 network 10.0.0.0
 default-information originate
 no auto-summary

R3:
Router#sh run | s rip|chain|1/0
key chain R3
 key 3
   key-string cisco3
interface FastEthernet1/0
 ip address 10.1.1.3 255.255.255.0
 ip rip authentication key-chain R3
router rip
 version 2
 network 10.0.0.0
 default-information originate
 no auto-summary
