篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了华为综合实验：STP与VRRP技术相关的知识，希望对你有一定的参考价值。
本实验使用华为eNSP模拟器，采用了VLAN技术、MSTP技术、VRRP技术、RIP等技术，搭建了一个简单的公司内网环境，实现网络的冗余及负载均衡
实验环境如下：
在sw1上配置
<Huawei>system-view [Huawei]sysname sw1 [sw1]vlan batch 10 20 #配置VLAN以及Trunk [sw1]int e0/0/1 [sw1-Ethernet0/0/1]port link-type access [sw1-Ethernet0/0/1]port default vlan 10 [sw1-Ethernet0/0/1]int e0/0/2 [sw1-Ethernet0/0/2]port link-type access [sw1-Ethernet0/0/2]port default vlan 20 [sw1-Ethernet0/0/2]int e0/0/3 [sw1-Ethernet0/0/3]port link-type trunk [sw1-Ethernet0/0/3]port trunk allow-pass vlan 10 20 [sw1-Ethernet0/0/3]int e0/0/4 [sw1-Ethernet0/0/4]port link-type trunk [sw1-Ethernet0/0/4]port trunk allow-pass vlan 10 20 [sw1]stp region-configuration #进入创建MSTP实例模式 [sw1-mst-region]region-name test #配置统一的实例名 [sw1-mst-region]revision-level 1 #配置一致的修订级别 [sw1-mst-region]instance 1 vlan 10 #配置实例1，将vlan10加入到实例1 [sw1-mst-region]instance 2 vlan 20 #配置实例2，将vlan20加入到实例2 [sw1-mst-region]active region-configuration #提交配置
在3sw1上配置

配置完毕，实现全网互通，如果一个核心交换机出现故障，也不会影响网络的正常通信了
