Three-layer Switch link aggregation (VTP + VLAN + STP)

Lab Requirements:

The dual-core architecture combines three-layer switching technology with VTP, STP, and Ethernet channels to achieve high-speed network conversion, high availability, high reliability and redundant backup functions, mainly for the network of dual-core topologies.

Experimental design:

1. Configure VLANs on the switch to control broadcast traffic.

2. Configure the Ethernetchannel between the 2 three-layer switches to achieve high-speed interoperability between the three-layer switches.

3. Configure VTP to implement a single platform management VLAN.

4. Configure STP to achieve a balanced load

5, three layer switches configure inter-VLAN routing for different VLAN interoperability

Implementation plan:

I. VLAN partitioning and IP address planning:

VLAN Ten 192.168.10.0/24 gateway:192.168.10.1

VLAN 192.168.20.0/24 gateway:192.168.20.1

VLAN 192.168.30.0/24 gateway:192.168.30.1

VLAN 192.168.40.0/24 gateway:192.168.40.1
