An example of the configuration of multiple ENSP clients to achieve intercommunication through Layer 3 switches and routers

Five clients successfully communicated with each other through two switches, one core switch, and one router.
First configure each client's IP and gateway, in order:
P1:ip: 10.0.1.2. Subnet mask: 255.255.255.0 Gateway: 10.0.1.1
P2:ip: 10.0.2.2. Subnet mask: 255.255.255.0 Gateway: 10.0.2.1
P3:ip: 10.0.3.2. Subnet mask: 255.255.255.0 Gateway: 10.0.3.1
P4:ip: 10.0.4.2. Subnet mask: 255.255.255.0 Gateway: 10.0.4.1
P5:ip: 10.0.52 Subnet mask: 255.255.255.0 Gateway: 10.0.51
Configure LSW2, set the interface mode of ports G0/0/2, G0/0/3 to ACCESS, and assign them to two VLANs: vlan2, vlan3. Set G0/0/1 The interface mode is TRUNK.

<huawei>undo terminal monitor
<huawei>sys
[huawei]
#
vlan batch 2 to 3
#
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan all
#
interface GigabitEthernet0/0/2
 port link-type access
 port default vlan 2
#
interface GigabitEthernet0/0/3
 port link-type access
 port default vlan 3

Also configure LSW3, set the interface mode of ports G0/0/2, G0/0/3 to ACCESS, and assign them to two VLANs: vlan 4, vlan 5. Set the interface mode of G0/0/1 to TRUNK.
After finishing configuring the core switch LSW1, set the interface mode of G0/0/2, G0/0/3 to TRUNK. Then create a new vlan from 2 to 6, and set the IP address of each vlan to each gateway address. Set the interface mode of G0/0/1 to ACCESS and add it to VLAN 6. Finally, set the static routing address of the switch

#
sysname Huawei
#
vlan batch 2 to 6
#
interface Vlanif1
#
interface Vlanif2
 ip address 10.0.1.1 255.255.255.0 
#
interface Vlanif3
 ip address 10.0.2.1 255.255.255.0 
#
interface Vlanif4
 ip address 10.0.3.1 255.255.255.0 
#
interface Vlanif5
 ip address 10.0.4.1 255.255.255.0 
#
interface Vlanif6
 ip address 10.0.6.1 255.255.255.0 
#
interface MEth0/0/1
#
interface GigabitEthernet0/0/1
 port link-type access
 port default vlan 6
#
interface GigabitEthernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan all
#
interface GigabitEthernet0/0/3
 port link-type trunk
 port trunk allow-pass vlan all
#
ip route-static 10.0.5.0 255.255.255.0 10.0.6.2
#

Finally, set the router AR2, set the IP of the two interfaces, and the static routing address.

#
interface GigabitEthernet0/0/0
 ip address 10.0.6.2 255.255.255.0 
#
interface GigabitEthernet0/0/1
 ip address 10.0.5.1 255.255.255.0 
#
ip route-static 0.0.0.0 0.0.0.0 10.0.6.1 //Any network segment will jump to 10.0.6.1
#

Test the connectivity of each client.
