MSTP+VRRP+链路聚合简单配置

实验需求1.存在两个用户业务网分布为VLAN 10和VLAN 20需要SW1作为VLAN 10根桥和VRRP-master设备2.SW2作为VLAN 20根桥和VRRP-master设备3.网段自行规划全网可达配置思路两条实例需要在 MSTP 域中配置不同的实例Instance例如 Instance 1 映射 VLAN 10Instance 2 映射 VLAN 20并分别指定根桥冗余机制当 SW1 故障时VLAN 10 的流量会自动切换到 SW2当 SW2 故障时VLAN 20 的流量会自动切换到 SW1如果 SW1 的上行接口G0/0/3断了它会自动降低 VRRP 优先级迫使 SW2 接管 VLAN 10 的流量防止“黑洞”现象链路聚合SW1 和 SW2 之间有两条连线将这两条物理链路配置为 Eth-Trunk链路聚合VRRP:SW1和SW2需配置vrrp并调整优先级使其在vid1和vid2中互为主备实验配置SW3[SW3]vlan batch 10 20[SW3]interface GigabitEthernet 0/0/1[SW3-GigabitEthernet0/0/1]port link-type access[SW3-GigabitEthernet0/0/1]port default vlan 10[SW3-GigabitEthernet0/0/1]q[SW3]interface GigabitEthernet 0/0/2[SW3-GigabitEthernet0/0/2]port link-type access[SW3-GigabitEthernet0/0/2]port default vlan 20[SW3-GigabitEthernet0/0/2]q[SW3]port-group group-member GigabitEthernet 0/0/3 GigabitEthernet 0/0/4[SW3-port-group]port link-type trunk[SW3-GigabitEthernet0/0/3]port link-type trunk[SW3-GigabitEthernet0/0/4]port link-type trunk[SW3-port-group]port trunk allow-pass vlan 10 20[SW3-GigabitEthernet0/0/3]port trunk allow-pass vlan 10 20[SW3-GigabitEthernet0/0/4]port trunk allow-pass vlan 10 20[SW3-port-group]qSW1[SW1]vlan batch 10 20 100[SW1]interface Eth-Trunk 1[SW1-Eth-Trunk1]port link-type trunk[SW1-Eth-Trunk1]port trunk allow-pass vlan 10 20[SW1-Eth-Trunk1]q[SW1]interface GigabitEthernet 0/0/1[SW1-GigabitEthernet0/0/1]port link-type trunk[SW1-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20[SW1-GigabitEthernet0/0/1]q[SW1]interface GigabitEthernet 0/0/3[SW1-GigabitEthernet0/0/3]port link-type access[SW1-GigabitEthernet0/0/3]port default vlan 100[SW1-GigabitEthernet0/0/3]q[SW1]stp region-configuration[SW1-mst-region]region-name m[SW1-mst-region]revision-level 1[SW1-mst-region]instance 1 vlan 10[SW1-mst-region]instance 2 vlan 20[SW1-mst-region]active region-configuration[SW1-mst-region]q[SW1]stp instance 1 root primary[SW1]stp instance 2 root secondary[SW1]interface Vlanif 10[SW1-Vlanif10]ip address 192.168.1.1 24[SW1-Vlanif10]vrrp vrid 10 virtual-ip 192.168.1.254[SW1-Vlanif10]vrrp vrid 10 priority 120[SW1-Vlanif10]vrrp vrid 10 track interface GigabitEthernet 0/0/3 reduced 30[SW1-Vlanif10]q[SW1]interface Vlanif 20[SW1-Vlanif20]ip address 192.168.2.1 24[SW1-Vlanif20]vrrp vrid 20 virtual-ip 192.168.2.254[SW1-Vlanif20]q[SW1]interface Vlanif 100[SW1-Vlanif100]ip address 14.0.0.1 30[SW1-Vlanif100]q[SW1]ip route-static 4.4.4.0 24 14.0.0.2SW2[SW2]vlan batch 10 20 200[SW2]interface Eth-Trunk 1[SW2-Eth-Trunk1]port link-type trunk[[SW2-Eth-Trunk1]port trunk allow-pass vlan 10 20[SW2-Eth-Trunk1]q[SW2]interface GigabitEthernet 0/0/2[SW2-GigabitEthernet0/0/2]eth-trunk 1[SW2-GigabitEthernet0/0/2]q[SW2]interface GigabitEthernet 0/0/4[SW2-GigabitEthernet0/0/4]eth-trunk 1[SW2-GigabitEthernet0/0/4]q[SW2]interface GigabitEthernet 0/0/3[SW2-GigabitEthernet0/0/3]port link-type access[SW2-GigabitEthernet0/0/3]port default vlan 200[SW2-GigabitEthernet0/0/3]q[SW2]interface GigabitEthernet 0/0/1[SW2-GigabitEthernet0/0/1]port link-type trunk[SW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20[SW2-GigabitEthernet0/0/1]q[SW2]stp region-configuration[SW2-mst-region]region-name m[SW2-mst-region]revision-level 1[SW2-mst-region]instance 1 vlan 10[SW2-mst-region]instance 2 vlan 20[SW2-mst-region]active region-configuration[SW2-mst-region]q[SW2]stp instance 1 root secondary[SW2]stp instance 2 root primary[SW2]interface Vlanif 10[SW2-Vlanif10]ip address 192.168.1.2 24[SW2-Vlanif10]vrrp vrid 10 virtual-ip 192.168.1.254[SW2-Vlanif10]q[SW2]interface Vlanif 20[SW2-Vlanif20]ip address 192.168.2.2 24[SW2-Vlanif20]vrrp vrid 20 virtual-ip 192.168.2.254[SW2-Vlanif20]vrrp vrid 20 priority 120[SW2-Vlanif20]vrrp vrid 20 track interface GigabitEthernet 0/0/3 reduced 30[SW2-Vlanif20]q[SW2]interface Vlanif 200[SW2-Vlanif200]ip address 24.0.0.1 30[SW2-Vlanif200]q[SW2]ip route-static 4.4.4.0 24 24.0.0.2SW4[SW4]vlan batch 100 200[SW4]interface GigabitEthernet 0/0/1[SW4-GigabitEthernet0/0/1]port link-type access[SW4-GigabitEthernet0/0/1]port default vlan 100[SW4-GigabitEthernet0/0/1]q[SW4]interface GigabitEthernet 0/0/2[SW4-GigabitEthernet0/0/2]port link-type access[SW4-GigabitEthernet0/0/2]port default vlan 200[SW4-GigabitEthernet0/0/2]q[SW4]interface LoopBack 0[SW4-LoopBack0]ip address 4.4.4.4 32[SW4-LoopBack0]q[SW4]ip route-static 192.168.1.0 24 14.0.0.1[SW4]ip route-static 192.168.2.0 24 24.0.0.1[SW4]interface Vlanif 100[SW4-Vlanif100]ip address 14.0.0.2 30[SW4-Vlanif100]q[SW4]interface Vlanif 200[SW4-Vlanif200]ip address 24.0.0.2 30[SW4-Vlanif200]qPC验证网络联通性
