1) A loopback address is normally advertised by OSPF as a host route. The command "ip ospf network point-to-point" enables one to specify that the interface should be advertised as a subnet route. What are the benefits for doing this?
2) Must a link cost be the same on for all routers that share the link? Is there a protocol reason for this? Some other reason? 3) In the Exstart phase, how is the master selected? Chappel's book says RID while Doyle's say highest interface IP address. Which is it? 4) I'm somewhat unclear on the Exchange and the Loading states. When a router goes into Exchange state, does it send all DDPs it knows about before processing any DDPs received from other adjancent neighbors? Thus, a router goes into Exchange state, sends all DDPs it knows about, then goes into Loading state, where it issues LSRs for LSAs it wants more details on? Is this the process? 5) Is there a difference between DBD and DDP packets?
