Hi Ron,
I know that if u did not specify the priority using the ip ospf
priority comamnd, then the default
priority is one.
I am not quite sure about when using the neighbor command. The
documentation says it is 0.
Jeff's book the same as well. When u look at Jeff's book, it does make
sense that the
default priority when using the neighbor command is zero.

Subject: Neighbor command Jeff Doyle Pg557-558
Hi pple,
I tried out the config in Jeff Doyle's book pg 557-558. But I have
some problem with the neighbor command.

I read from the documentation and Jeff's book that if priority for
the neighbor command is not specified, it'll
be priority 0, which implies it will not participate in DR/BDR
election. WIth the above config,
the hub router should become DR since the spoke router cannot
participate in DR/BDR election.
At the spoke, the configuration will change the priority to 1 after
a while even when I keyed in the priority to be 10. The same thing
happens to the hub. WHy ?? If we can't change the priority, then
why have the option. I am using 11.2(18)
I know that we can set ip ospf priority at the interface. I just
wonder why the neighbor command behave so strangely.
THanks
