hi,all I have a question about ospf link state database synchronization process. I think,two routes will be 1.exstart in which determine master/slave 2.exstart in which exchange database description packets(DDs).DDs contrain enough information(LSA headers) to find more recent LSAs than in its own link state database.Router then record these LSAs in its own request list. 3.loading in which last DD has received and routers check request list ,send request packets and receive update packets. 4.full in which request list is empty. My question is ,since slave only in response to DD packets it receives from the master.If slave's link state database is bigger than master's,when master sends last DD,set M(ore) to 0,slave also responds with a DD,set M(ore) to 0.Slave's rest link state database is lost and ignored by master.Is than true? _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
