华为交换机MSTP+VRRP典型场景实验

文章插图
 
1. 这是一个由三台交换机组成的倒三角型二层交换网络;
2. 网络中有4个VLAN:10、20、30、40;
3. 接口编号如图所示;
4. VLAN10对应的网段为192.168.10.0/24;VLAN20对应的网段为192.168.20.0/24;
VLAN30对应的网段为192.168.30.0/24;VLAN40对应的网段为192.168.40.0/24;
各VLAN的网关均为.254的地址,该地址为VRRP组的虚拟地址;
5. SW1的vlanif10和vlanif20的IP地址分别为:192.168.10.253、192.168.20.253
SW1的vlanif30和vlanif40的IP地址分别为:192.168.30.252、192.168.40.252
6. SW1的vlanif10和vlanif20的IP地址分别为:192.168.10.252、192.168.20.252
SW1的vlanif30和vlanif40的IP地址分别为:192.168.30.253、192.168.40.253
2 实验需求
1. 由于网络中VLAN较多,并且存在二层环路因此使用MSTP实现环路避免,同时实现负载分担 。
2. 将vlan10、20映射到MSTP实例1;将vlan30、40映射到MSTP实例2;
3. MSTP实例1Block掉的端口为SW3的GE0/0/23;实例2Block掉的端口为SW2的GE0/0/22;
4. 为了提高网络的网关层冗余能力,在SW1及SW2的vlanif10、vlanif20、vlanif30、vlanif40上部署VRRP,一共4组 。而VRRP的Master及Backup需与MSTP的主、备根重叠 。也就是说SW1的vlanif10及vlanif20为各自VRRP组的Master,此外vlanif30及vlanif40为各自VRRP组的Backup;SW2正好相反 。
3 实验步骤及配置
SW3的配置如下:
#在SW3上创建VLAN,并将接口加入相应的VLAN
[SW3] vlan batch 10 20 30 40
[SW3] interface GigabitEthernet0/0/22
[SW3-GigabitEthernet0/0/22] port link-type trunk
[SW3-GigabitEthernet0/0/22] port trunk allow-pass vlan 10 20 30 40
[SW3] interface GigabitEthernet0/0/23
[SW3-GigabitEthernet0/0/23] port link-type trunk
[SW3-GigabitEthernet0/0/23] port trunk allow-pass vlan 10 20 30 40
#配置MSTP,将vlan10 20映射到实例1,将vlan30 40映射到实例2
#在SW3上,MSTP实例1及实例2的优先级保持默认32768
