Has someone a working setup with the following conditions:
CRS1xx-2HnD or 8337/8327 (hAP ac/RB2011-2HnD)
CAPsMan and Wifi as CAP on the same hardware as the CAPsMan [edit]
CAP-Client
Two SSIDs with vlan-mode=use-tag and two different vlan-ids on the same bridge
CAPsMan datapaths configured for local forwarding
VLAN handling with switch chip features (untagged access ports, tagged trunks)
Router has IP on both VLAN-ids configured with CAPsMan-SSIDs
I’m just wondering if this works for someone without “strange” issues?
For me it seems working correctly at first - but some wireless clients for (only one) VLAN are not able to “see” some wired clients. Even if both of them are able to communicate to the router IP address (get addresses with DHCP and can access internet) there seems to be no ARP working between them. But router has both mac addresses in his arp table and mac address of wired clients is in the right VLAN on unicast-fdb in the switch chip.
I’m sorry? I didn’t get that point. What should multicast routing help for that kind of problems? The packets shouldn’t leave the same ether/bridge. I see the problem between the kind of connection the new bridge vlan translation is done with capsman and the “old style” switch chip vlan translation: That configuration has proofed on this device as working for many years on the same CRS - even with “old style” wlan1 as member of the bridge.
Multicast helper is not about routing, it avoids wifi broadcast by translating any wifi bum traffic to unicast. I fixed my wifi ARP issues by enabling it and suggest that you at least give it a try.
Ok, now I understand. Sorry for the dismiss - I didn’t know about the usage of the helper for “multicast” AND simple “broadcasts”. O:-)
I still don’t see the relation to multicast - which I believe is IPv4 and not ARP - but I’ll give it a trial…
PS: And it doesn’t cover the question why the problems only occur if the interface is configured with vlan-mode=use-tag and vlan-id=xxx
Maybe it’s just a bug in RouterOS!?
To be honest, I never tried it without use-tag. I configured two SSIDs with different VLAN IDs and use-tag, hit ARP issues and found out I could make it work with multicast-helper.
