 Post subject: Newbie Needs Some Guidance...
PostPosted: Wed Jun 30, 2010 2:15 am 
The image is a screenshot of my network I need to get connected with instructions.
The only successful test I have is pinging 1.0.0.1 from R2 and 1.0.0.2 from R1
As far as I can tell, OSPF is setup correctly but, "show ip ospf neighbor" gives me nothing and "show ip route" doesn't show any device connected via OSPF.
I am unable to ping from router to router (except for R1 and R2).
I'm pretty sure my addressing is correct and that there should be some communication and neighbor discovery. but it's not happening.
Any information on why this is messing up would be greatly appreciated.

OSPF is trying to send the hello packet to 224.0.0.5 from 172.16.0.9. The second IP is correct and is considered the designated router. 224.0.0.5 doesn't exist on this network. I can't figure out why my traffic is routing to that IP.

224.0.0.5 is multicast ip of OSPF (all routers)

My advice is to read some theory about OSPF first. After, will be very easy make configurations.

yeah. I just reread that part in my book and was about to post. my bad. like I said, newbie. trying to get some practice in for the CCNA.

if you look in my original post, it has the information for what I did to setup OSPF and interfaces. Currently I'm trying to get communication between R3 and R1. R1 and R2 work fine through the frame relay.

Does anyone see any issue with the way I've configured those two routers that might explain why R3 and R1 aren't communicating? or at least, "ping" and "show ip ospf neighbor" and "sho ip route" do not tell me that it can see the other router. the hello packet makes it though so I know data can get across.

please try to configure everything without "this" authentification.

if every thing will work ok, then add authentification.
