If I am understanding this correctly. There are no routers up in the network. I turn on 3 routers simultaneously at the same time. The routers will first select the BDR. They will then look for the DR. Since none exist, the BDR will be promoted to DR. Then another election will be held to find a new BDR. Is this correct?

The DR is chosen from the list of routers that declared themselves designated routers (this is why a high-priority router that comes up late won't take over the DR role from an existing DR), or if no router declared itself DR, then the BDR will become DR (this is why a high-priority router that came up late won't necessarily become DR even if the existing DR dies). See RFC2328, Page 75 for more details. Thanks, Zsombor DeVoe, Charles (PKI) wrote: > > I am reading the CCNP/CCIP BSCI Study Guide by Todd Lammle > from Sybex.
