Problem with VRRP (seems like a bug?)

I have a vrrp setup:

Router 1: Prio 100 (ROS 3.28)
Router 2: Prio 50 (ROS 3.28)
Router 3: Prio 10 (ROS 3.28)

Preemption mode is active.

If i use no Authentication everything works like it should. If i use “simple” authentication everything works like it should. If i use “ah” authentication with a 16-char long password there is a messup: Router 1 AND Router 3 are taking the mastership.

Router 3 is seeing the packets to 224.0.0.18.

Is this a bug?

Hi!
Since a VRRP multi-cast does not leave it’s own broadcast domain (unless you are routing multicasts (but even still you shouldn’t be routing VRRP multicasts)) why do you need authentication? I’m not trying to bypass your question about a bug (I’ve encountered a few with VRRP (ok.. maybe not bugs but more like erratic behaviour)), just wondering why authentication is necessary.

This bug will be fixed in next version.
