All:
I just submitted a quick ticket because I'm having difficulty getting licensing on a few virtuals in my environment. I noticed that I submitted a ticket about VRRP v3 incompatibilities with Cisco back in November, and I haven't been reached out to on that ticket.
Is that typical? I'm using quite a few of these devices in my day to day work and am not sure how this would fare if I had an actual insurmountable issue...?
Are you using VRRP with IPv4 or IPv6?
With IPv4, there are some implementations that include the pseudo-header in the VRRP checksum calculation and this can lead in some interop problems.
This incompatibility has been an industry problem until rfc5798bis:
https://datatracker.ietf.org/doc/draft- ... fc5798bis/; which should clarify that with section 5.2.8.
Looks like RouterOS does not offer the possibility to exclude IPv4 pseudo-header from the VRRP checksum calculation; from a ROS point of view and as other users suggested, if you want to fix this interop between CISCO and ROS you should probably try VRRPv2.
