every 30 second to make Data Base refreshment

Answer / sandeep agarwal

224.0.0.5 - AllSPFRouters: Used to send OSPF messages to all
OSPF routers on the same network. The AllSPFRouters address
is used for Hello packets. The DR and BDR use this address
to send Link State Update and Link State Acknowledgment packets.


224.0.0.6 - AllDRouters: Used to send OSPF messages to all
OSPF DRs (the DR and the BDR) on the same network. All OSPF
routers except the DR use this address when sending Link
State Update and Link State Acknowledgment packets to the DR

I am just getting into this,I want to jump ahead a do the packet tracers in discovery working at a small to medium business or ISP but I am trying to get the last lab putting it all together. Does anyone have anything for this. I know it is ahead of me but I would like to get this so I can look at the beginning and understand it more
