介绍

我正在尝试在运行BIRD 路由守护程序的两台主机之间使用 RIPv2 协议建立基本通信。

我有一个有地址Host A的接口。 我有另一台主机，其接口具有 address 。这些接口通过电缆直接连接。如果我在两台机器上添加静态路由，我可以在两台机器之间 ping 通。enp010.0.1.50/24
Host Benp110.1.1.25/24

配置文件

我有以下bird.conf内容Host A：

protocol kernel {
        learn;                  # Learn all alien routes from the kernel
        persist;                # Don't remove routes on bird shutdown
        scan time 20;           # Scan kernel routing table every 20 seconds
        export all;             # Default is export none
}

protocol device {
    scan time 10;           # Scan interfaces every 10 seconds
}

protocol direct {
        interface "enp0"
}

protocol rip MyRIP {    
    export all;
    import all;
    interface "enp0" { mode multicast;};
}

bird.confonHost B是相同的，除了替换enp0为enp1

初步结果

在两台主机上启动鸟守护程序后，我可以做一个tcpdump -ni enp0 -vv

13:21:41.943537 IP (tos 0xc0, ttl 1, id 4933, offset 0, flags [none], proto UDP (17), length 132)
    10.1.1.25.520 > 224.0.0.9.7742: [udp sum ok] UDP, length 104
13:21:41.943704 IP (tos 0xc0, ttl 1, id 150, offset 0, flags [none], proto UDP (17), length 272)
    10.0.1.50.520 > 224.0.0.9.7742: [bad udp cksum 0xec48 -> 0x1219!] UDP, length 244

我可以跳入birdcl命令行并运行show rip neighbors并获得一个空表。

让它发挥作用

如果我将地址设置在同一个子网上，我可以运行show rip neighbors并且可以10.0.1.50在我的邻居列表中看到。

包起来

如果链路的两端不在同一个子网上，如何让这些路由器将彼此列为邻居？

我必须对网络如何工作有某种不正确的心理画面，路由器不需要一直与不在同一子网上的邻居通话吗？

我没有挂断特定于 BIRD 的答案。

我想了解一些关于 Rip V1 和 V2 的事情，但我不确定我是否正确，

据我所知，Rip V1 不会“宣传”子网掩码，也不支持 VLSM。如果我理解正确即使Rip V1例如支持 VLSM 也没关系，因为 Rip V1只“宣传” IP 地址，如果有人可以确认/扩展/纠正我，我将非常感谢，谢谢大家祝你有愉快的一天。

这是我在 GNS3 中设置的拓扑。

RIP-EIGRP 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
