cisco vlan with 2 dhcp pools

If you are referring to different servers, absolutely, just use multiple helper addresses. If you're referring to multiple pools on different routers/switches, sure, it'll simply be first responding server that the client will take the IP from.

Sometimes our ip pool for vlan x has no free leases, but we need more IPs in vlan x. Is it possible when pool1 has no free leases that pool2 give its IPs (from a different subnet) to the hosts in vlan x? Boert

Why overcomplicate things, why not just increase to pool size of the existing scope?

We have the subnet mask 255.255.255.0 and the pool size is xxx.xx.

Could you specify a smaller subnet - 255.255.252.0?

As it is completely useless to let your DHCP hand out an IP address that is outside the IP range for the subnet, you will have to change your network configuration anyway.

You need to allocate a new subnet address, or vacate the one next to it (xxx.xx.205.xx) and extend the 204 network into 205.

Change the subnet mask into 255.255.254.0 and extend the scope to xxx.xx.204.10 - xxx.xx.205.254.

Ok, I will try it and post the result.

Many thanks Boert

It works! Many thanks for your help!! Boert
