Hello,
Below is my network diagram,
After CRS112 Transparent OLT is working Fine but can’t seen to work the 2nd OLT as that olt can only take VLAN334 but I have tried everything but can’t connect that OLT via VLAN
please Help
I hope those OLTs are not connected to same physical port of CRS112 (situation digram can be understood as if they are).
So what exactly is covered by “I have tried everything”? Please share config of CRS112 (textual export) so we can see the bigger picture and then we might get some idea of how to fix the config.
I hope those OLTs are not connected to same physical port of CRS112 (situation digram can be understood as if they are).
Both OLTs are on different port

Don’t use bridge VLAN filtering on CRS112 … this switch can’t offload such setup to hardware and you will end up with loading CPU. You should configure VLAN on switch chip. See these manual pages to see, how it should be done:
https://wiki.mikrotik.com/wiki/Manual:CRS1xx/2xx_series_switches
https://wiki.mikrotik.com/wiki/Manual:CRS1xx/2xx_series_switches_examples
Conceptually you want to have ether3 tagged outside of switch and untagged inside the switch. Which is the other way around from what usually is (tagged inside device, untagged outside … that’s where PVID comes into play). I’m not sure if your problem can be solved by settings on ether3 port only, could be you’ll have to set same VLAN ID on all of involved switch ports (from config posted I assume that’s ether2, ether3 and ether4) … with PVID set on untagged ports (ether2 and ether4) and keeping port ether3 tagged.
I am quite new in networking and routerOS, Can you please let me know How can I achieve that?

I’m sorry, I don’t have any CRS1xx device so I can’t write you exact recipe for what you need. Either some good soul with 1st hand experience on CRS1xx passing by might help you. Or you can dive in the ocean of networking with Mikrotik (experienced forum members will help you with this). Or you can hire a consultant to do it for you.
