Hi all, can someone possibly answer these questions I have, I have been reading my cisco icnd 2 book, But I am still unsure of a few items.
1, When ospf starts, and forms a neighbour relationship on a lan with other routers, does each router only send an LSA to the DR about itself? and what kind of lsa is it, a router lsa or link lsa?
2, What does ospf define as a point to point link, if I have 2 ethernet ports directly connected but with a /30 address between them, will it class this as point to point?
3,How does the SPF algorithm work out the best way to a subnet, in that way i mean, how does it know to reach a certain subnet before a routing table is in place?
