Is the function of the DR and BDR and the other router designations in a local neighborhood really that important?
I have read that it really is not all that important because all routers in the same area have the same database.
But, aren't the local area changes propagated from the DR router?
In my application, we have our carrier providing Internet, we have a default route distributed from the HQ edge router to our Firewall via ospf.
This is then passed to the Internal network from the Firewall inside interface to the core network 6509 switches.
Our HQ site
edge router-->firewall-->6509-->7206 to DR
Our DR site also has an Internet connection. We get that default route passed to us via BGP that is distributed into ospf to the HQ Core network on the 7206 router.
The DR default route has a higher AD than the HQ internet on the 7206 router.
All of these devices are in the same ospf area.
When we loose our HQ site internet, we get the DR site default route.
Does it matter all that much for me to manipulate the DR router election?
It seems the 6509 switches would be the best place in this situation to have the changes in the route tables to be sourced from, unless I am not understanding the funtion of the DR router.
For example, would it matter all that much if the 7206 was elected as the DR rather than the 6509 switches?
