Hi Narbik,
My reasons for adding "broadcast", unless the requirement states
otherwise are:
- convenient,
- error prone,
- time-saving.
This are particularly important as far as CCIE lab is concerned.
When configuring WAN FR PVC, I would NOT have to pay much attention to the
requirements of the routing, and multicast, or even some miscenlinous topic
such as NTP which use broadcast or multicast.
I always configure "bp", as alias for "ping 255.255.255.255 timeout 1 repeat
1". When configuring L2 (Switching, FR, or P2P Serial), I only need to issue
"bp" and count responses, to see if I have full reachibility, instead of
having to type actual IP addresses.
This approach worked perfect for me!
Regards,
Huan

If your OSPF network is non-broadcast type, then your routing protocol will
send hello and update via unicast, and will simply not send updates via
broadcast. It will operate the same way as if you configure the map without
the keyword broadcast. Having that broadcast keyword does not force the
router to generate rudundant broadcast! Nothing different!
Then why use it????????????????????
