lsa序列号
1.线性序列号
2.环形序列号
3.棒棒糖序列号
ospf版本
ospf version 1 实验环境
ospf version 2 ipv4

maxage
当lsa的年龄到达maxage时,将被从所有数据库中删除.(默认3600秒,1小时)
lsrefresh time刷新时间是定期确认lsa是否到达最大年龄时间将其复位.(默认1600秒,半小时)
dijkstra's spf算法
同一区域内的路由器又完全相同的数据库.
每个路由器把自己定位到树的根-each router in the area places itself into the root of the tree that is built.
到一个特定的目标的最好的路径基于最低的cos值-the best path is calculated with respect to the lowest total cost of links to a specific destination.
最好的路由放入路由表-bestroutes are put into the forwarding database(routing table)
