eNSP network segment host interconnection - static

Posted by FRSH on Thu, 23 Dec 2021 07:30:43 +0100

Test purpose

Test the interconnection of different network segments through three-layer switches
The three-layer switch is directly connected to the router to connect the external network to realize the connection between the host and the external network

Application scenario

The simulation implementation can be used for interconnection of different network segments such as different floors, different departments / departments.
The simulation implementation can be used to connect the external network by different departments / departments.

testing environment

eNSP 1.3.00.100 V100R003C000SPC100
window 10

Test topology

Area floor 1 and floor 2 are 192.168 respectively 10.0/24，192.168. 20.0/24 segment network.
There is a second floor switch on each floor, and the host access port is added.
Add a three-layer core switch to realize the interconnection of all switches.
A router is added to connect the external network and the core switch. Different network ends can be connected to the external network according to the routing configuration.
All hosts configure IP addresses manually. Dynamically configure IP reference eNSP network segment host interconnection DHCP
All hosts are interconnected through switches, and the same network segment can be directly interconnected by default.
