Experiment name: construction of Huawei layer 3 Router dhcp

Experimental topology diagram

3. Configuration idea: before configuring dhcp, let the whole network interwork first, and finally configure the dhcp server, first configure the ip address of pc7.pc8, create vlan10.vlan20 on switch lsw3, so that the vlan can be interconnected, then create vlan30, and configure ip address of vlan30, configure ip address on AR3, configure ip address at port 0 of vlan30, then configure dhcp service on router AR3, and configure dhcp relay on lsw3.

4. Configuration steps:

Step 1: configure the Ip address of pc7,pc8

Ip address 192.168.10.1 255.255.255.0

Gateway 192.168.10.254

Quit

Ip address 192.168.20.1 255.255.255.0

. Gateway 192.168.20.254

Quit

# next, create vlan 10dvlan20 on lsw3 to enable interworking between vlan.

# vlan10

Quit

Vlan 20

Quit

Int vlan 10

Ip address 192.168.10. 254 255.255.255.0

Undo shutdown

Int vlan 20

Ip address 192.168.20.254 255.255.255.0

Undo shutdown

Test with the command ping 192.168.20.1

# the above figure shows that the experiment is successful

# next create VLAN 30 on lsw3

# vlan 30

Int vlan 30

Ip address 192.168.30.1 255.255.255.0

Undo shutdown

# configure the ip address on the router port g0and0and0

Ip address 192.168.30.2 255.255.255.0

Undo shutdown

# configure a static route on the router to the 192.168.0.0 network segment, so that pc can ping the interface 192.168.30.2

# ip route-static 0.0.0.0 0.0.0.0 192.168.30.1

# Test with ping command

The above shows that the whole network has been interconnected.

| # next, configure the dhcp server on the router

Dhcp enable

Ip pool vlan 10

Network 192.168.10.0 mask 255.255.255.0

Gateway-list 192.168.10.254

Dns-list 8.8.8.8

Lease day 1

The same goes for dhcp enable

Ip pool vlan 20

Network 192.168.20.0 mask 255.255.255.0

Gateway-list 192.168.20.254

Dns-list 8.8.8.8

Lease day 1

# configure to find the DHCP server address pool in global mode

# interface g0/0/0

Dhcp select global / / find dhcp in global mode

# next configure dhcp trunk on the switch

Int vlan 10

Dhcp select relay

Dhcp-relay server-ip 192.168.30.2

Int vlan 20

Dhcp select relay

Dhcp relay server-ip 192.168.30.2

# testing and verification

# the above pictures show that the test is successful
