Creating new subnet/DHCP range.
Posted on 2009-04-28
I have been tasked with creating another subnet with a range of DHCP addresses.
Currently we have all servers and workstations on 10.1.254.0 255.255.255.0. Servers/Printers are configured with a static IP and reservations for them are on the DHCP server. Workstations pull DHCP.
We are running out of IP addresses, so we want to create the 10.1.253.0 255.255.255.0 subnet. Making this subnet the one with DHCP running for the workstations and the servers/printers remaining on the '254' subnet with no DHCP.
All hosts are on a stack of HP Procurve Switches that connect to a Cisco ASA to get out to the web.
Besides creating the range on the DHCP server and removing the '254' range from the pool, what else will need to be configured to make these subnets talk to each other?
Do any routes need to be added to the ASA?
I feel like I am forgetting something, perhaps how the DHCP server sitting on '254' will be able to provide addresses to workstation on the '253'? But these will be on the same switch, so not a problem?
Thank you for any help.
