Greetings,
I am practicing DR/BDR election on NBMA networks. My topology is described
below. I am trying to influence DR/BDR election based on "neighbor x.x.x.x
priority" command. (while keeping the default priority under interface). I
don't think its working.
I gave priority 20 to neighbor 150.50.100.5 but I don't see this router
becoming DR.
Any help in understanding "neighbor x.x.x.x priority" command is
appreciated.
