如何让 OSPF 查看通过千兆端口中继的 VLAN

网络工程 思科 局域网 ospf
2022-02-14 15:22:35

我对此比较陌生，我一直在尝试各种配置，但没有什么能抓住。我有三个路由器，有各种 vlan。vlan 正在工作。路由器使用 OSPF 互相访问。但是我无法让一侧的主机看到另一侧的主机。

我最初将所有链接都作为 /30 子网，但我不确定这是否正确。我尝试了其他人，但没有尝试检测到千兆位，所以我删除了它们

我不确定如何处理 G/端口。我希望有人能帮助我或为我指明正确的方向。

我希望这个编辑有帮助。这是很多信息。

您没有将 VLAN 通告给其他路由器，因为它们不是 OSPF 域的一部分。

OSPF 配置定义了哪些接口包含在 OSPF（即域）中。您只包括了路由器之间的链接，因此这就是 OSPF 将通告的全部内容。

为此，请在 OSPF 部分中创建包含路由器子接口的网络语句。

例如，在 R1 上，您可以包括：

network 172.20.0.1 0.0.0.0 area 0

这将通告 VLAN 15。您可以为其他 VLAN（在两个路由器上）执行其余操作。
