Summary

During this lab we added OSPF Authentication to the framework from the lab

Steps

Border Router: Network 1

enable 
config t 
interface GigabitEthernet 0/0 
ip ospf message-digest-key 1 md5 testing 
ip ospf authentication message-digest

East Router: Network 2

enable 
config t 
interface GigabitEthernet 0/0 
ip ospf message-digest-key 1 md5 testing 
ip ospf authentication message-digest

Data Center: Network 3

enable 
config t 
interface GigabitEthernet 0/0 
ip ospf message-digest-key 1 md5 testing 
ip ospf authentication message-digest 
exit
interface GigabitEthernet 0/1 
ip ospf message-digest-key 1 md5 testing 
ip ospf authentication message-digest 
exit
interface GigabitEthernet 0/2 
ip ospf message-digest-key 1 md5 testing 
ip ospf authentication message-digest

West Router: Network 4

enable 
config t 
interface GigabitEthernet 0/0 
ip ospf message-digest-key 1 md5 testing 
ip ospf authentication message-digest
