Hi Carl,


The address 224.0.0.5 and 224.0.0.6 is used by OSPF to exchange link state information. This is done by the DR router which informs all the other routers about any link state change.


If you have asked if there is a network change does the DR tell the router about it, the answer is yes.


Cheers

if there is a change in the network topology then the Drother(s) (non DR/BDR) wil send an update to the DR/BDR. These are listening

to the address 224.0.0.6 and then the DR will send this same update to the BDR and the Drother(s) using address 224.0.0.5

In response to that. What hardware would you suggest if you wanted to design a OSPF network supporting up to 100-200 ospf processes per box.
