网络工程 - 无法在 Cisco XRv 设备上 Ping VRRP 虚拟 IP - 吾爱随笔录

我有两个在 GNS3 设置中运行的 XRv 路由器，因此我可以 ping 它们的常规接口，但是当我配置 VRRP 时，我无法 ping VRRP 虚拟 IP（除了当前充当活动的路由器）。这个问题也会影响到设备的实际数据包路由（发送到虚拟 IP 作为下面使用的主机的网关的数据包。）

是否有我可能错过的配置选项，或者这只是 XRv 软件中的一个已知问题？如果我尝试使用 HSRP 而不是 VRRP，我会遇到同样的问题。

路由器配置：

R1：

interface GigabitEthernet0/0/0/1
ipv4 address 192.168.102.101 255.255.255.0
!
!
router vrrp
 interface GigabitEthernet0/0/0/1
  address-family ipv4
   vrrp 5
    priority 150
    address 192.168.102.155
   !
  !
 !
!

R2：

interface GigabitEthernet0/0/0/1
 ipv4 address 192.168.102.105 255.255.255.0
!
router vrrp
 interface GigabitEthernet0/0/0/1
  address-family ipv4
   vrrp 5
    priority 100
    address 192.168.102.155
   !
  !
 !
!

输出自show vrrp

从主机设备 ping R1 和 R2 上的接口（通过交换机连接到两者）

PC1> ping 192.168.102.101
84 bytes from 192.168.102.101 icmp_seq=1 ttl=255 time=4.854 ms

PC1> ping 192.168.102.105
84 bytes from 192.168.102.105 icmp_seq=1 ttl=255 time=5.304 ms

从主机 ping 虚拟 IP

从活动路由器 (R1) ping 虚拟 IP
