VRRP與接口狀態聯動簡介

VRRP主備備份功能有時需要額外的技術來完善其工作。例如，Master設備到達某網絡的鏈路突然斷掉時，VRRP無法感知故障進行切換，導致主機無法通過Master設備遠程訪問該網絡。此時，可以通過VRRP與接口狀態聯動，解決這個問題。

當Master設備發現上行接口發生故障時，Master設備降低自己的優先級（使得Master設備的優先級低於Backup設備的優先級），並立即發送VRRP報文。Backup設備接收到優先級比自己低的VRRP報文後，切換至Master狀態，充當VRRP備份組中新的Master設備，從而保證了流量的正常轉發。

配置注意事項

· 保證同一備份組的設備上配置相同的備份組號（virtual-router-id）。

· 不同備份組之間的虛擬IP地址不能重複，並且必須和接口的IP地址在同一網段。

· 一個VRRP備份組最多可以配置監視8個接口。並且，當設備為IP地址擁有者時，不允許對其配置監視接口。

組網需求

如圖1所示，用戶通過Switch雙歸屬到SwitchA和SwitchB。用戶希望實現：

· 正常情況下，主機以SwitchA為默認網關接入Internet，當SwitchA或者其上下行接口故障時，SwitchB接替作為網關繼續進行工作，實現網關的冗餘備份。

· SwitchA和SwitchB之間增加帶寬，實現鏈路冗餘備份，提高鏈路可靠性。

· SwitchA故障恢復後，可以在20秒內重新成為網關。

配置思路

採用VRRP主備備份實現網關冗餘備份，配置思路如下：

1. 配置各設備接口IP地址及路由協議，使各設備間網絡層連通。

2. 在SwitchA和SwitchB上部署VLAN聚合，實現VLAN101~VLAN180二層隔離三層互通，節省了IP地址。

3. 在SwitchA和SwitchB上創建Eth-Trunk接口並加入成員接口，實現增加鏈路帶寬，提供鏈路冗餘備份。

4. 在SwitchA和SwitchB上配置VRRP備份組。其中，SwitchA上配置較高優先級和20秒搶佔延時，作為Master設備承擔流量轉發；SwitchB上配置較低優先級，作為備用設備，實現網關冗餘備份。

5. 在SwitchA上配置VRRP與接口狀態聯動，監視接口GE1/0/1和接口GE1/0/2，實現主設備故障時，VRRP備份組及時感知並進行主備切換。

操作步驟

1. 配置設備間的網絡互連

# 配置核心層設備各接口的IP地址，以SwitchA為例。SwitchB和SwitchC的配置與SwitchA類似，詳見配置文件。
