Hello everybody

I have a setup like this Connection between Core routers is Point-toPoint
. Connection between Core routers and remote routers is
point-to-multipoint.
Underlying L2 technology is Multiaccess (VPLS).

Which ospf network type is better between CoreRt1 and others? Default
ospf type is Broadcast. Is there any advantuage in using
point-to-multipoint here.

Please recommend.
