我正在配置具有以下拓扑的网络:
我需要做的是提供一项由 Anycast 提供并由 OSPF 宣布的服务。我设法在路由器上配置了 OSPF。我还在两台服务器中创建了一个具有相同 IP 的虚拟接口。但现在我不确定如何在服务器上配置 Bird,以便客户端可以通过 Anycast IP 访问它们。我正在模拟 GNS3 上的网络。
我在 VirtualBox 上安装了一个 Ubuntu 20.04.1 服务器作为 VM,这个 VirtualBox 在我学校的远程服务器上运行并安装GNS3
在这个 VM(Ubuntu 服务器)上。到目前为止,一切都很好。但是当我尝试使用我的本地机器(MacOS Catalina)并TunnelBlick
连接到这个远程服务器时,我得到了错误:TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
.
到目前为止,在阅读了几个答案之后,已经尝试过:
nc -uvz <remote server IP/also VM IP> 1194
成功!scp
使用公共 IP 在主机和 VM 之间进行 - 这意味着 VM 的 IP 是正确的并且可以访问。GNS3
了几次并更新了配置文件。请帮我解决一下这个。
这是我在 GNS3 中设置的拓扑。
路由器 R2 的 RIP V2 协议识别并通告在 EIGRP 中通告的两个网络,即使上述信息应该仅通过重新分发接收。我如何确保 RIP 仅通告我想要通告的那些子网,而不是该特定路由器上可能存在的该有类网络的所有子网?
以下是来自路由器 R2 和 R3 的 Show Ip route 和 Show Running-config 信息,
R3#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, 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
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route
