Hello,
I’m having two CCR2004-1G-12S+2XS running v7.19.1. Both devices have a bridge and an LACP bond between them. The Bond (and all the VLANs) are in the bridge on both routers.
VLAN1 has two VRRP’s:
- VRID1, vrrpv3, ipv4
- VRID 101, vrrpv3, ipv6
IGMP Snooping is enabled on both routers.
In v.7.18.1, VRRP works. One becomes master (Running) and the other is standby.
As soon as I upgrade to v7.19.1, both become master. (this also happened in v7.19 betas and in v7.19)
Downgrading to 7.18.1 fixes the problem.

Is anyone else having the same problem?
On Router1 doing a
/tool sniffer quick interface=VLAN1-Office ip-protocol=112
shows me:
v7.18.2:

But on v7.19 it only shows:

Disabling IGMP Snooping fixes the problem. However, then I live in a multicast hell..
