when you use neighbor command to define the OSPF router's neighbor,
the word 'broadcast' does not need to be included to the frame map
statement. Unless you use 'ip ospf network broadcast' then word
'broadcast' is needed at the end of the frame map statement.
The 'broadcast' keyword is to allow forwarding of broadcast. With
that you will not need to specify all the neighbors like what you did
when you use neighbor command. The frame map statement with broadcast
keyword will make OSPF router to treat it like on a broadcast
network.
That explain why neighbor command you don't broadcast key but you need
to specify all the ospf neighbors.
May all beings be happy

Subject: OSPF neighbors, frame relay broadcast
I was working through the CCIE bootcamp lab 1in my mind again, and
have a question. The hub frame router was configured as a single sub
int on a serial, multipoint. The spoke routers were configured with
frame right on the serial, no sub. Okay, iarp resolved the ip's and
life was good.
Now add ospf. All interfaces are non-broadcast as far as ospf is
concerned. That means neighbors. Now on the sub, the "frame relay map
ip *.*.*.* dlci broadcast" command is used.
Under OSPF, neighbors are defined. I guess I'm wondering if the
interfaces are non-broadcast and neighbors need to be defined, why the
"broadcast" keyword on the end of the frame-relay map statements?
