     104== Router 4 OSPF Configuration ==
     105
     106Let's configure Router 4 for OSPF Routing. First, let's enable the OSPF Daemon just like we did in Router 1, 2 and 3!

     110Explanation:
     111
     112* Enable enables the OSPF Daemon Interface.
     113* Configure Terminal enables Global Configuration Mode.
     114* Router OSPF enables RIP Configuration Mode.
     115* Redistribute RIP enables OSPF to learn all RIP routes.
     116* Router-id 0.0.0.3 specifies the Arbitrary Router-ID which you can think of as a name for this Router.
     117* Network 192.168.62.0/24 area 0 configures OSPF for each interface, and specifies which OSPF area of which this Interface is a member. We can get very granular with our configurations, as a Router may belong to 1 or more OSPF Areas.
     118* Network 192.168.65.0/24 area 0 configures OSPF for each interface, and specifies which OSPF area of which this Interface is a member.
     119* Exit exits OSPF Configuration Mode
     120* No access-list vtylist deny any removes the explicit denial rule that ships default with the Daemon, and lets us create a new rule. Just like IPTables, anything after the explicit denial rule will be disregarded.
     121* Access-list vtylist permit 192.168.62.0/24 permits traffic on this interface.
     122* Access-list vtylist permit 192.168.65.0/24 permits traffic on this interface.
     123* Access-list vtylist deny any replaces the explicit denial rule. We keep this there for security, and only implicitly permit traffic for each interface.
     124* Exit exits Global Configuration Mode
     125* Write Memory saves the OSPF running-configuration.
     126
     127* Configured interface for Router 1 and Access-List for Router 1.

     129== Conclusions ==
     130
     131Now, if you plug in Router 1 to Router 4 via Ethernet 2 on Router 1 and Ethernet 2 on Router 4, and unplug Router 1 Ethernet 3, OSPF should automatically learn and use the alternative route. MD5 Auth will be added to this tutorial shortly. Let's get your head around these fundamentals first, and I will work with you through it.
