if i have a core switch participating in an ospf process with quite a few number of routers in an area (say 20 routers on a frame relay), is it a common practice to allow the core switch to be a dr or a bdr?
i have configured the core to have an ospf priority of zero for it not to participate in the dr/bdr election..Am I on the right track?
it depends on the setup of your network. Since you say that you are using 20 routers connected with Frame Relay, I assume that this is a hub-and-spoke network ? In this case, the hub router should be the DR, also because it usually has the most CPU power and memory. That means that your core switch can have a priority of 0 and never be a DR or BDR. What is the function of the core switch in your network ?
in that case I would let the core L3 switch be the BDR. An infrared link to me sounds like it could be more vulnerable to a failure than your core switch, which is probably directly physically connected to yuor main router.
