OSPF interception

To avoid interception on a segment between two OSPF nodes, do the following:

- configure the ospf intrface as nonbroadcast

- configure the nodes to be neighbor each other

To verify the settings:

# show ip ospf interface interface

# debug ip ospf hello

OSPF priorty 0

An OSPF router with 0 priority will never be a BDR or DR.

Furthermore, giving 0 priority to an OSPF router will remove the DR/BDR status from it immediately and will trigger a new election.

CCIE written passed

After several times postponing to take the exam, I finally decided to take the exam on 11 Jan 2009 and passed it.

I know that passing the written exam doesn't mean anything except that now I can register for the lab exam. However, considering my hard work to prepare this exam, I should celebrate this achievement :D

Now it's the time to read the blueprint for the lab and learn harder on the lab exam preparation.
