Can you run 2 DHCP servers on the same network?
Not really, unfortunately. On the same subnet, you absolutely cannot run two DHCP servers that assign addresses from the same range. However, on the same subnet, you can have two DHCP servers that assign addresses from different ranges. You can run two DHCP servers on the subnet and let one distribute addresses .
How does a client choose a DHCP server?
The client discovers a DHCP server by broadcasting a discover message to the limited broadcast address (255.255. 255.255) on the local subnet. If a router is present and configured to behave as a BOOTP relay agent, the request is passed to other DHCP servers on different subnets.
How many types of scopes are there in DHCP?
DHCP scopes are used to define ranges of addresses from which a DHCP server can assign IP addresses to clients. Scopes fall into Normal, Multicast and Superscope categories as follows: Normal Scope – Allows A, B and C Class IP address ranges to be specified including subnet masks, exclusions and reservations.
What’s the benefit of having multiple DHCP pools?
As Kev explained, the benefit of having multiple DHCP pools is that you can dynamically assign IP addresses for several different VLANs. The initial DHCPDISCOVER message is a broadcast, so the router will choose the DHCP pool based on the interface it received the request on (comparing it to the default-router defined in the DHCP pool).
How to create DHCP pool for multiple VLANs?
Create three VLANs and add 2 PCs to each VLAN. Configure the DHCP server on the switch and create three DHCP pools. Assign a DHCP pool to each VLAN. Configure all PCs as DHCP clients. Verify that all PCs receive their IP configuration from the DHCP server. Test connectivity between all PCs.
Which is the default router for a DHCP pool?
As for a L3 switch, the default-router for each DHCP pool configuration will be the IP address assigned to each SVI which in turn also serves as the gateway for each VLAN.
Can you have more than one DHCP server on one network?
This is the most basic example of having more than one DHCP server on the same network. Multiple DHCP servers PT 2: DHCP servers that serve the same network segment.
