Thanks all, Sorry for the corrupted diagram..
Corerouter1 and corerouter2 are connected each other as point-to-point .
Three routers(RTR-A, RTR-B, RTR-C) are connected to Corerouter1 and
Corerouter2 by means of VPLS which means
Gi1/0/1 of RTR-A, Gi1/0/1 of RTR-B, Gi1/0/1 of RTR-C and Gi1/0/1 of
Corerouter1 are in same layer access connection. (Lets says VLAN1)
Gi1/0/2 of RTR-A, Gi1/0/2 of RTR-B, Gi1/0/2 of RTR-C and Gi1/0/2 of
Corerouter2 are in same layer access connection. (Lets says VLAN2)
All the interfaces are in area0.
Here there is no Hub and Spoke model.

Re: Case: Which ospf is better? Broadcast or Multicast
Hi. Unfortunately text diagram got broken in the mail.
In broadcast network you would have to use central router as DR, with
spokes set as priority 0.
But P2M is a better choice here, since it would allow you to specify costs
per neighbor, therefore you could alter your topology much more easily.

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.
