The router allocates IP address (DHCP) and DHCP relay.

The main function of a vro is network addressing, which sometimes needs to be used to assign IP addresses. However, assigning a router address increases the load on the router, so sometimes we can assign the address to a PC.

1. Use the router to assign an IP Address:

Router> en

Router # conf t

Enter configuration commands, one per line. End with cntl/Z.

Router (config) # int VLAN 1

Router (config-If) # ip dhcp pool vlan1 // sets the IP address pool. vlan1 is just a name

Router (DHCP-config) # network 192.168.1.0 255.255.255.0 // you can specify the allocated IP address segment.

Router (DHCP-config) # default-router 192.168.1.1 // sets the Default Gateway

Router (DHCP-config) # DNS-server 8.8.8.8 // sets the DNS server

Router (DHCP-config) # lease 2 // sets the address lease time, in days

Router (DHCP-config) # ip dhcp excluded-address 192.168.1.100 // retain unallocated addresses

After configuring the router, remember to turn on the switch. I am in the vmare virtual environment. Therefore, you must first disable the DHCP service of the virtual machine so that the client can normally receive the IP address assigned by the router.

2. DHCP relay:

Router (config) # int VLAN 1

Router (config-If) # IP address 192.168.1.1 255.255.255.0

Router (config-If) # IP helper-address 192.168.1.100

Router (config-If) # No Shutdown

Install the DHCP service on the server of the relay proxy and manually set the IP address to 192.168.1.100. Create a DHCP address pool and activate it. You can set the default gateway and DNS server in "scope options.
