Environment

  • Python version: 3.5.2
  • NetBox version: 2.4.4

Steps to Reproduce

  1. Create a new VRF with unique IP space enforcement enabled.
  2. Create IP address 192.0.2.1/24 in the VRF with a role of VRRP.
  3. Create a second IP 192.0.2.1/24 in the VRF with a role of VRRP.

Expected Behavior

NetBox should allow the creation of the second IP, since it is necessary to replicate shared (e.g. VRRP) IP addresses among multiple interfaces.

Observed Behavior

Validation of the new IP address fails, complaining that a duplicate IP address has been found.
