sir thanks, this configuration was very helpful. sir, i have a problem in my project so please help me …below is the name of my project.

Configuration And Comparison of IPv6 Routing Protocols (RIPng,OSPFv3,BGPv4)Using Packet Tracer Simulator
and analyzing on OPNET.

kindly give my your email for further help…thanks

I think there is a “mistake” in your configuration. In fact, you do not advertise internet by this command :
R1(config)#router ospf 1
R1(config-router)#network 20.10.10.0 0.0.0.3 area 0

Here, you include internet on your area 0.
I think the right configuration to do here, is to do a default static route on R1 and share it to the others by ospf like that :

router ospf 1
passive-interface Serial1/3 #do not send Hello packets on this interface
network 10.10.10.4 0.0.0.3 area 0
network 10.10.10.0 0.0.0.3 area 0
default-information originate #send default route to others routers in the area
!
ip route 0.0.0.0 0.0.0.0 Serial1/3

In reply to Chris. Hi Chris, thanks for suggestion and I'm glad you found the article helpful. It's a simple lab to configure OSPF on Cisco routers for new students. Everyone can add and change the lab whatever they want.

Just a suggestion, but I connected another serial between R2 and R3 using 10.10.10.8/30 and added those networks to OSPF. This allowed me to shut down a serial interface on any of the serial links and witness OSPF topology update accordingly to take another path, then watch again as I no shut the interface. This might be a good thing to add to the lab?
