OSPF debug commands

[hounddog]

Hi Todd,

The debug ip ospf packet command, you state in your example, the Corp router can see both sent and received Hello packets.

I only see rcv packets. I also notice that the network sending the packets are on 176.16.10.0 network. Shouldn't this be from our 10.1.x.0 networks?

This command, shows only the hello packets you are receiving. (yes, I wrote that wrong).

The hello's only contain the "RID" of the neighbor router, not which network they are connected to.

Cheers!

Thanks for clearing that up that Todd,

I should have read further along in the chapter 'Configuring Loopback Interfaces' where you set up the loopback to be in the 172.16.1.0 network before posting. :oops:

Thanks.

This is great. It made you stop and think, and now you learned a lot about OSPF, RID's and DR and BDR's, which are a critical CCNA objective.
Keep up the hard work!

Hehe. I had the exact same experience earlier today. I was truly scratching my head wondering where all the class B addresses were coming from until I got to loopbacks!
