DHCP configuration and experiment records in Cisco

1. Cisco DHCP configuration ideas

In global Mode

Ip dhcp xxxx name DHCP address pool XXX, only for marking

Network allocation address and subnet mask

Default-router assigns a gateway

DNS-the server allocates DNS, which can be separated by spaces.

.....

Exit

In global Mode

Ip dhcp ex start address end address allocation reserved address is not used for DHCP, such as gateway

2. Multi-vlan dhcp highlights

If the SVI interface is used as the gateway

IP helper-address xx. xx allocates the DHCP server address

Multiple VLANs can be allocated on multiple VLAN interfaces.

Multiple DHCP address pools are used on the DHCP server. The IP address pool CIDR block must be in the same CIDR block as the SVI interface of the preceding IP helper-address. There are several VLANs that accompany several address pools.
