area0配置了区域间认证,
R1跟R2上配置了vitrual-link
R1
interface Loopback0
ip address 1.1.1.1 255.255.255.255
ip ospf message-digest-key 1 md5 ccie
ip ospf 1 area 0
!
router ospf 1
router-id 1.1.1.1
log-adjacency-changes
area 0 authentication message-digest
area 1 virtual-link 2.2.2.2
!
===========我是诚实的分割线===========
R2
interface FastEthernet0/0
ip address 192.168.1.2 255.255.255.0
ip ospf 1 area 1
duplex auto
speed auto

问题,R1上配置了密钥,R2为什么不用配置密钥,virtual-link就能建立邻居关系?
clear ip ospf proccess一样可以建立邻居关系
