Need advice for CRS + CCR mixed environment

Hi,
I’m a sysadmin within a small provider and I’m a little stuck studying a few optimization options for a MK-based server room.

Here’s the scenario:

    • servers are all attached to CRS-125 switches with no VLANs
  • one CCR router are performing all the routing tasks

What I’m trying to accomplish:

    1. have every server dropped out of its switchport if the NIC’s MAC address doesn’t match the assigned IP
  1. have all the servers broadcast-isolated with each other but still be able to perform normal L2 operations with each other
  2. …with a precise exception for a PXE server (but this is a further step I can think about later)

I’ve been testing many setups for weeks (VLANs, port isolation, firewall, IPP…), but still no joy :frowning: Can you help me?

Thank you everybody in advance! :slight_smile:
