Matt: Yes, a well known one. The default ospf network type for
point-to-multipoint and physical frame-relay interfaces is
Non-Broadcast. This network type elects a DR and also uses unicast for
hellos. You should configure the hub as the DR and disable the spokes
from participating in the DR election process. See the other post re
priority (hint). The other commands that must be configured are
neighbor commands on the hub to point to the spokes.
HTH, Fred.
