When a SPAN port is added to an interface, CARP breaks.

The source address of the CARP announcement, which should be from the IETF VRRP mac range changes to the mac of the physical interface.

  • Priority changed from Very High to Very Low
  • Target version deleted (2.3.4-p1)

CARP is known to not work well with any kind of bridging, including span ports.

It is not a common enough requirement or need to warrant giving priority. A span port could be configured at the switch instead as a simple workaround.
