Topology diagram as above,

Experiment Objective: 1, realize the interconnection of each different network segment's host

2, dynamic demonstration under the process of hot backup, VLAN1 and VLAN 2 main line is the left host, VLAN3 and VLAN 4 belongs to the backup machine under normal circumstances.

Experimental steps: 1, first establish the vlan1,2,3,4 on the switch, then associate the VLAN with the switch interface, then the port F20,f21 trunk,

VLANs are implemented with interface affinity:

Inter FAS0/1 Entry Interface

Switch Mode acc

SW ACC Vlan1

2, implement create lvlan1,2,3,4 on the left multilayer switch, then Port trunk, then give each VLAN a gateway IP,

Inter VLAN 1

IP Add 192.168.1.1 255.255.255.0

Exit

Trunk:inter the port to FAs 0/20

SW TR Enc Dot

SW MO TR

3, the same operation on the right multilayer switch, only slightly different, when the VLAN set the gateway IP, must be different from the input on the left, as follows

Inter VLAN 1

IP Add 192.168.1.2 255.255.255.0

Exit

4, the switch on the left to implement the operation of the host, the right to implement the operation of the backup machine

Inter VLAN 1

Standby 1 IP 192.168.1.250//Set up virtual gateways

Standby 1 priority 105//increase the default precedence by 5 points, default 100

Standby 1 preempt//enable preemption function

Inter VLAN 2

Same operation

Inter VLAN 3,inter VLAN 4

On the right side of the backup machine operation as follows

Inter VLAN 3

Standby 3 IP 192.168.3.2 255.255.255.0

Standby 3 Priority 105

Standby 3 preempt

Attention:

1, don't forget to turn on the routing feature: IP routing

2, to set the IP gateway of each PC to 250 of the above experiment,
