A priority of 0 means that the router is not eligible. The router with the highest priority becomes the Designated Router. If a router with a lower priority is the Designated Router and a new router with a higher priority comes online, the Designated Router will not change. Authentication...
After a DR is elected, it will remain so until you restart or manually clear the IP OSPF process. Re-election is a manual process in case of OSPF. If you have higher priority set on the router that needs to be elected a DR, no shut it before the others. The Designated Router is e...

The router with the highest priority is elected the DR. If there is a tie, then the router with the higher router ID takes precedence. After the DR is elected, the BDR is elected the same way. A router with a router priority set to zero is ineligible to become the DR or BDR. ...
The priority can be any value between 0 to 255 (0 configures the interface to never become the OSPF Designated Router (DR) on a broadcast interface). NCLU Commands cumulus@switch:~$ net add interface swp51 ospf6 hello-interval 5 cumulus@switch:~$ net add interface swp51 ospf6...
o However n If a new OSPF router joins the network with a higher priority or router ID, the current DR and BDR do not change. o It would become the new BDR only if the current DR failed or the new DR only if the current D 39、R and BDR failed. Step 3: Discover Routes o ...

DR election is based on a router’s OSPF Priority, which is a configurable value from 0 (not eligible for DR) to 255. The router with the highest priority becomes the DR. In the event of a priority tie, the router with the highest Router ID (based on interface addressing) wins. Once...
Routers in a broadcast or NBMA network elect the DR and BDR by router priority and ID. Routers with a router priority value higher than 0 are candidates for DR and BDR election. The election votes are hello packets. Each router sends the DR elected by itself in a hello packet to all th...
