我有这样的拓扑：

在此处输入图片说明

这个 Router0-1 的 Gig0/0/0 ip: 10.0.12.1/24, Router0-2 的 Gig0/0/0 ip: 10.0.12.2/24, Gig0/0/1 ip: 10.0.23.2/24, 这个 Router0-3 的 Gig0/0/0 ip: 10.0.23.3/24,

首先，所有路由器接口都被通告到区域 0 中。

现在，我宣布 Router0-3 的 Gig0/0/0 和 Router0-2 的 Gig0/0/1 到 Area1，但 Router0-2 得到以下日志：

00:57:06: %OSPF-4-ERRRCV: Received invalid packet: mismatch area ID, from backbone area must be virtual-link but not found from 10.0.23.2, GigabitEthernet0/0/1

00:57:16: %OSPF-4-ERRRCV: Received invalid packet: mismatch area ID, from backbone area must be virtual-link but not found from 10.0.23.2, GigabitEthernet0/0/1

00:57:26: %OSPF-4-ERRRCV: Received invalid packet: mismatch area ID, from backbone area must be virtual-link but not found from 10.0.23.2, GigabitEthernet0/0/1

00:57:36: %OSPF-4-ERRRCV: Received invalid packet: mismatch area ID, from backbone area must be virtual-link but not found from 10.0.23.2, GigabitEthernet0/0/1

....

我在 Router0-3 中尝试过 clear ospf prgress，仍然是这个问题。

我试过你的post实验，当我在一个区域将R3的接口分配给Area1时，R2会得到这个Error Receive日志。

但是如果你在 R3 中no router ospf 1，然后启动一个新的 OSPF 进程，并将接口添加到区域 1 中，则不会出现此故障。

然后显示Router2的OSPF数据库，有显示完美无缺。
