Re: Clients lose IPv6-Connectivity after a few minutes [SOLVED]

For RB5009 you can enable "Multicast Querier" viewtopic.php?p=906424#p906140 or disable L2 hardware offloading.
Both methods work with igmp snooping.

Re: Two DHCP servers on two tagged VLANs - not working [SOLVED]

There are several issues with RB5009 switch chip, just for testing could you please disable Hardware offload on bridge ports.

I'm not sure it will help, just to eliminate switch chip.

Re: Bridge VLAN egress does not strip tag RB5009 7.1.1 [SOLVED]

Thank you. I reset the configuration and started from scratch. I followed your instructions and used multiple example files from the VLAN thread. Here are my exact steps.

Re: RB5009 ROS 7.1.1 IGMP Snooping issue with L2 HW offload [SOLVED]

The issue was with ipv6 RA packets, I have no idea how it depends on IGMP querier and L2 HW offload.

Re: v7 filter dynamic-in set check gateway option not found

@MikroTik
Are there any plans to implement equivalent of dynamic-in and connected-in chains? It's possible to create workaround with scripts for dynamic-in but for connected it is not possible (I would like to add comments for example).
