CCNA-17、OSPF-v2;v3的配置

interface FastEthernet0/0
 ip address 192.168.12.1 255.255.255.0
 ip ospf priority 2    #设置ospf接口优先级，使其当DR

R1#clear ip  ospf process  #清除ospf进程

OSPF的路由标识

O - OSPF, 
IA - OSPF inter area 
N1 - OSPF NSSA external type 1, 
N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, 
E2 - OSPF external type 2

OSPFv3 IPv6 配置

ipv6 unicast-routing    #启用ipv6的功能
ipv6 router ospf 1
router-id 2.2.2.2

ipv6是在接口地下宣告的，不是用network宣告的
interface Ethernet0/0
ipv6 address 3FFE:FFFF:1::1/64
ipv6 ospf 1 area 0       #启用某个进程，指定Area 的ID
ipv6 ospf priority 20    #配置优先级
ipv6 ospf cost 20

Router1#
interface s1/1
ipv6 address 2001:410:FFFF: 1::1/64ipv6 ospf 100 area 0

interface s2/0
ipv6 address 3FEE:B00 : FFFF:1::2/64ipv6 ospf 100 area 1
ipv6 router ospf 100
router-id 10.1.1.3

Router2#
interface s3/0
ipv6 address 3FEE:B00 : FFFF:1::1/64ipv6 ospf 100 area 1
ipv6 router ospf 100
router-id 10.1.1.4

·查看OSPF邻居表
Router# show ipv6 ospf neighbor
·显示路由表的信息
Router# show ipv6 route
·清除IP路由表的信息
Router# clear ipv6 route *
·在控制台显示OSPF的工作状态
Router# debug ipv6 ospf

排错：
R2(config-if)#ip ospf hello-interval 40 #hello包的时间设置40秒，可自定义。
查看双方hello发送时间，要设置一样才能起来。
