Hey guys, I've read a section about exchanging DDP from McGraw-Hill's BSCN but I'm not sure whether I interpreted right or not. This is my understanding. After a router received information about its neighbours, it will try to get information to establish its link state database. So, it will establish an adjacency with another router. The router with the highest router ID will become the master and it will send information to the slave. If the slave believes that it is still missing information, it will send out link state request packets to get informations it needs. Now here's the question, what happens if the new router (ie just came onto the network) has the highest router ID? It will send information to other routers but it won't know that itself is lacking routes since it just came on. Therefore, it will not send link state request packets. Is that right? Thanks in advance Hing _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com. _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
