Command Usage
• Set the priority to zero to prevent a router from bei ng elected as a DR
or BDR. If set to any value other than zero, the router with the highest
priority will become the DR and the router with the next highest
priority becomes the BDR. If two or more routers are tied with the
same highest priority, the router with the higher ID will be elected.
• If a DR already exists for an area when this interface comes up, the new
router will accept the current DR regardless of its own priority. The DR
will not change until the next time the election process is initiated.
