虚链路认证

R2#sh running-config vie | se in ipv6 router ospf 
ipv6 router ospf 1
 router-id 2.2.2.2
 area 1 virtual-link 3.3.3.3 authentication ipsec spi 256 md5 12345678901234567890ABCDEFABCDEF
 
 R3#sh running-config vie | se in ipv6 router ospf 
ipv6 router ospf 1
 router-id 3.3.3.3
 area 1 virtual-link 2.2.2.2 authentication ipsec spi 256 md5 12345678901234567890ABCDEFABCDEF

验证：

接口认证

R2#sh run vi | se in 0/0     
interface Ethernet0/0
 no ip address
 ipv6 address 2001:CE02::1/64
 ipv6 ospf authentication ipsec spi 257 md5 12345678901234567890ABCDEFABCDEF
 ipv6 ospf 1 area 1
 
 R3#sh run vi | se in 0/0     
interface Ethernet0/0
 no ip address
 ipv6 address 2001:CE02::2/64
 ipv6 ospf authentication ipsec spi 257 md5 12345678901234567890ABCDEFABCDEF
 ipv6 ospf 1 area 1

Clear ipv6 ospf process 刷新进程，查看show命令。

（注意：IOS有些版本会导致物理链路和虚链路都down了。导致spi 混乱，造成邻居都建立不起来。
解决办法：
删掉虚链路认证和接口的认证，然后先配置接口的认证，再配置虚链路的认证，就可以了。
IOL：L3_ADVENTERPRISEK9_M_15.4_2T.bin 测试不会出现此问题。
