Configuring Multiple DHCP Pools

[pgeho1961]

How exactly is this done? I have a situation where I must support multiple DHCP pools which need to be assigned to seperate VLAN's. Is there a way to do this? or can you only support a single vlan across a particular device? Thanks...

Hi Friend,

You can configure multiple DHCP pools for different subnet/vlans.

Your config should look something like this

ip dhcp pool

network x.x.x.x x.x.x.x

default-router x.x.x.x

!

ip dhcp excluded-address

Same way you configure multiple DHCP pools just configure these command with different network command and with different dhcp pool names.

Also if you want to exclude the addresses from the DHCP pool "ip dhcp excluded-address " command should be used.

"default-router x.x.x.x " command is used to assign the default gatway for clinets for that DHCP pool.

Thanks Ankur - that's what I ended up doing.

Appreciate the post!

Hi,

Simply create another pool with addresses for the others interface. The router is smart enough to work out which interface the DHCP request came in from and will assign from the appropriate pool accordingly.
