Hi Guys,
running v.6.49.7 on top of CRS326-24S+2Q+ sometimes i have to restart the switch because it is not forwarding IPv6 multicast traffic anymore.
In this case, no neighbor discovery is possible, also IPv6-RA is not possible anymore. With tcpdump -eni eth0 ip6 on the servers they connected to the malfunction switch, there is complete silence about IPv6 traffic.
As soon the switch was restarted, IPv6 starting acting normal.
Is there any reason why the switch causes this type of issue?

Do you have IGMP Snooping enabled in bridge settings? It's buggy since version 0.001 and was never fixed, not even in V7.

Check for Bridging and Switching - FastForward which disables MAC Learning..
Re: CRS326-24S+2Q+ IPv6 forwarding Stopps working
IGMP Snooping is not enabled.
Used the switch configuration as is from default. Only did IP and VLAN Settings.

The router clock is way off (Jan 1970) which breaks TLS. The export is incomplete which really hinders but what's here has issues as well.
VLAN Table incomplete; nothing under "/interface bridge vlan" for VLAN 1,2000,2001; VLAN 530 omits "bridge" as "tagged" or "untagged".
Recommended practice is "bridge" is tagged member of every VLAN except VLAN 1 which is untagged.
Assign router management IP address to bridge interface (VLAN 1).
Add vlan interfaces using bridge as the underlying interface.
