Already posted this here:
NearCCIEs,
1) The "neighbor x.x.x.x priority y" command appears on your router only
if the "ip ospf priority" value on your local interface is not equal zero.
Otherwise does not even appear on router mode configuration.
2) The "neighbor x.x.x.x priority y" resets to one, because it reads the
"ip ospf priority" value from the neighbor's interface. If you change the
priority value on the interface at the other end, your local router will
read the value if of course you entered the "neighbor x.x.x.x priority y"
command.
Regards, Voytek

As far as I know this command does not work.
You must set priority on the interface independent of the neighbor
statement.

Subject: Ospf NBMA strange experience
I am trying following in my tes bed.
Routers R2, R3 and R4 connected with frame. R3 is a
hub with a physical interface to the frame, R2 is
through the subinterface and R4 is through physical
interface connected to the frame. The frame network is
NBMA. I have tried following to make R3 DR.
Try 1)
Configure following line under ospf on R2
neighbor ip_address_R3 priority 10
Also under subinterface i have ip ospf network
nonbroad
Under R4 ospf statements I have
neighbor ip_address_R3 priority 10 and ip ospf net
nonbroad for the interface
Under ospf of R3 I have
neighbor ip_address_R2 priority 0
neighbor ip_address_R4 priority 0
When i do this the highest ip address becomes the DR,
the funny thing is now when i check my running configs
my neighbor statements are different,
On R3 i see sh run as
neighbor ip_address_R2 priority 1 and ip_address_R4
priority 1. My show startup-config is still the
original that i configrured (With 0 priority)
It does not stop here on R2 which is chosen as the DR
My neighbor statement changes from priority 50 to
priority 1 again in the running config only not in the
startup config. Same happens on R4 also.
Any suggestions???
Sandro
