LAN 2 interface for DHCP

[#1]

Hi All,

Is there  possibility to segregate traffic for DHCP between LAN1 and LAN 2 interfaces for different VRF?

There is a MGMT interface which is globally routed and can establish grid connectivity?

Thoughts?

Hi Gokul,

Yes, it is possible to segregate DHCP traffic between different LAN interfaces in different VRFs (Virtual Routing and Forwarding). This can be achieved by configuring separate DHCP servers for each VRF or by using DHCP relay agents that direct requests to the appropriate DHCP server based on the incoming interface nystateofhealth ny gov

Here’s a high-level approach:

1. Separate DHCP Servers: Set up independent DHCP servers for each VRF. Each server would need to be aware of the specific address pools for its respective network.

2. DHCP Relay: If using a single DHCP server, configure DHCP relay on the interfaces of each LAN. This means that when a DHCP request comes in, it is forwarded to the correct DHCP server based on the VRF configuration.

3. VRF Configuration: Ensure that your VRFs are properly configured to handle the routing between the interfaces and that the DHCP traffic is isolated. This may involve specific routing policies to ensure that the DHCP requests/responses are handled in the correct VRF context.

4. Management Interface: Since you have a management interface that is globally routed, you can utilize it for monitoring and managing the DHCP servers, but keep in mind that DHCP traffic should remain segregated between the VRFs.

5. Testing: After configuring, make sure to test the DHCP requests from clients on both LAN interfaces to confirm they are being processed correctly by the intended servers.
