I have one host site and planning to put in one more host site. I am using OSPF area0 and will have to use area 0 at new host site as well. I was just wondering if there is any way I can calculate how much bandwidth I may require to connect these 2 area 0's.
Since OSPF does not trasnmit anything frequently except for Hellos, bandwidth may not be a big issue. However it could impact the convergence time when there is a flooding due to topology change, since it would basically depend on how many LSAs need to be exchanged, which is linked to how many routes you have in your network, whether you do summarization, how stable your network is etc. Following links gives you some tips about design considerations for OSPF :
I do agree that the bandwidth here is directly proportional to the network size or number of LSA's. And if there is a change in topology then the convergence of the area0 routes will depend on the bandwidth available in between those 2 area 0. But is there any way by which it can be calculated for given size of network. Or is it only we have to assume some bandwidth here.
