DHCP Server

I have configured the Cisco 3825 router as a DHCP server for leasing an IP addresses to me remote intra network.How many IP address can this Cisco 3825 router can lease?

Thanks and Regards,

S.Venkataraman.

Re: DHCP Server

The address range is specified in the network configuration line.

The addresses you include, if any, in the ip dhcp excluded-address statement will be excluded from the pool.

Re: DHCP Server

Hi Venkat,

To add some detail to Victor's explanation:

You need to configure the following, just an example:

conf t

ip dhcp pool 1

network 192.168.1.0 /24

The result of this will be that the DHCP server will be able to lease the number of ip addresses that are within a /24 subnet, i. e. 254.

With a /25 prefix the number of available ip addresses will be 126. etc.

In reality it can be less, as you have already at least one ip address manually assigned in a given subnet: the ip address of the interface of the DHCP relay agent, or that of the DHCP server itself.

Hi, Istvan:

I didn't give him the actual commands to enter to configure DHCP because he says he already configured it. :-)

Hi Victor,

No problem. I just gave it for better understanding of the principle.

Cheers:

Istvan
