0SPF路由单区域配置
配置过程
1)创建一个 OSPF 进程,进程号的范围为1~65535。
Router ( config )# router ospf [ process - id ]
2)配置当前路由的 ID ,相当于每台路由器在 OSPF 中的名称,同一区域内不能相同,格式和 P 地址相同,都是点分十进制,取值范围为0.0.0.0~255.255.255.255。如果不指定,默认选物理地址最大的那个
Router ( config - router )# router - id [ id - number ]
3)将直连网络发布到 OSPF 中,这里和 RIP 协议不同的地方在于,发布时需要添加所对应网段的反掩码和区域编号。
Router ( config一router )# network network - address Wildcard - mask area -n umber
反掩码就是四个255减去掩码
