组网需求： 楼层1和楼层2分别通过两条线路做冗余接入交换机（本示例只考虑vrrp，暂不考虑其他方面）。当其中一段链路故障时，能通过另外一条链路传输。 配置信息： <lsw9>dis cu # sysname lsw9 # vlan batch # stp mode stp # interface Ethernet0// port link-type access port default vlan # interface Ethernet0// port link-type access port default vlan # interface GigabitEthernet0// port link-type trunk port trunk allow-pass vlan # interface GigabitEthernet0// port link-type trunk port trunk allow-pass vlan stp instance cost # return <lsw9> -------------------------- <lsw11>dis cu # sysname lsw11 # vlan batch # stp mode stp # interface Ethernet0// port link-type access port default vlan # interface Ethernet0// port link-type access port default vlan # interface GigabitEthernet0// port link-type trunk port trunk allow-pass vlan stp instance cost # interface GigabitEthernet0// port link-type trunk port trunk allow-pass vlan # return <lsw11> ------------------------- <lsw7>dis cu # sysname lsw7 # vlan batch # stp mode stp # interface Vlanif1 # interface Vlanif10 description to L ip address 10.155.10.254 255.255.255.0 vrrp vrid virtual-ip 10.155.10.252 vrrp vrid priority vrrp vrid preempt-mode timer delay # interface Vlanif20 ip address 10.155.20.254 255.255.255.0 vrrp vrid virtual-ip 10.155.20.252 vrrp vrid priority vrrp vrid preempt-mode timer delay # interface Vlanif30 description to L ip address 10.156.40.254 255.255.255.0 ip address 10.156.30.254 255.255.255.0 sub vrrp vrid virtual-ip 10.156.30.252 vrrp vrid virtual-ip 10.156.40.252 vrrp vrid priority vrrp vrid preempt-mode timer delay # interface Vlanif100 ip address 10.10.10.1 255.255.255.0 # interface MEth0// # interface GigabitEthernet0// port link-type access port default vlan # interface GigabitEthernet0// port link-type trunk port trunk pvid vlan port trunk allow-pass vlan to # interface GigabitEthernet0// port link-type trunk port trunk allow-pass vlan # ospf area 0.0.0.0 network 10.10.10.0 0.0.0.255 network 10.155.0.0 0.0.255.255 network 10.156.0.0 0.0.255.255 # return -------------------------------------- <lsw8>dis cu # sysname lsw8 # vlan batch # stp mode stp # interface Vlanif1 # interface Vlanif10 description to L ip address 10.155.10.253 255.255.255.0 vrrp vrid virtual-ip 10.155.10.252 # interface Vlanif20 description to L ip address 10.155.20.253 255.255.255.0 vrrp vrid virtual-ip 10.155.20.252 # interface Vlanif30 description to L ip address 10.156.30.253 255.255.255.0 ip address 10.156.40.253 255.255.255.0 sub vrrp vrid virtual-ip 10.156.30.252 vrrp vrid priority vrrp vrid preempt-mode timer delay vrrp vrid virtual-ip 10.156.40.252 # interface Vlanif200 ip address 10.10.20.1 255.255.255.0 # interface MEth0// # interface GigabitEthernet0// # interface GigabitEthernet0// port link-type trunk port trunk allow-pass vlan # interface GigabitEthernet0// port hybrid pvid vlan port hybrid tagged vlan to # interface GigabitEthernet0// port link-type trunk port trunk allow-pass vlan # ospf area 0.0.0.0 network 10.155.0.0 0.0.255.255 network 10.156.0.0 0.0.255.255 network 10.10.20.0 0.0.0.255 # return <lsw8> ----------------- <Huawei>dis cu # sysname Huawei # stp instance root primary stp enable # interface GigabitEthernet0// ip address 10.10.10.254 255.255.255.0 stp enable # interface GigabitEthernet0// ip address 10.10.20.254 255.255.255.0 stp enable # interface GigabitEthernet0// ip address 61.128.128.6 255.255.255.0 # return <Huawei>
