Hi Eric,
Since there are only 2 network types that require DR election (broadcast and
non-broadcast), the likelihood is that under your given scenario, you would
be allowed to use the non-broadcast network type for the ospf routers.
Since the non-broadcast network type requires the 'neighbor' commands to
form adjacency, you can specify the priority of 0 for the remote spokes when
you issue the neigbor commands on the hub.
For example, if R1 is supposed to be the DR and the other routers R2 and R3
never to be DRs or BDRs, then given the network type of non-broadcast, you
may issue the following commands under the R1 ospf routing process.
R1
router ospf 1
neighbor 2.2.2.2 priority 0
neighbor 3.3.3.3 priority 0
(IP addresses assumed)
When the routers 'bargain' for the adjacency, R2 and R3 would be forced to
join with a priority of 0 therefore disqualifying them from becoming DR or
BDRs.
Therefore, you do not need to manually set the priority of 0 on the two
spoke routers.
My 2 pesewas!
