Reloading Switch or Router During election process in OSPF for DR and BDR ?

[ajazahmed1]

Hi Folks,

I have created an OSPF lab which is multi-access environment. I have changed the designated and back-up designated router. The election process is depended upon the priority number. I have given one router as Priority 255 and other one 254. The problem is when I configured everything still the routers are not accepting the changes, unless or until rebooting the complete network which has four routers connected through a switch. 
Reloading or rebooting is the only way to accept the changes ? Can someone please explain ? 

Thanks,

Ajaz Ahmed

The OSPF election process is not preemptive. A reboot or disconnect of all devices or a 'clear ip ospf process' is required. What you are seeing is normal.

Hey Collin, thanks. 'clear ip ospf process' is somewhat helpful.
