Vlan/loop issue?

Tue Dec 10, 2019 11:19 pm

Good day, i have the following scenario:
2 x crs3, ros 6.46
vlan9 cctv network, vlan22 management network.
first crs:
eth24 uplink from management network, bridge port pvid 22
eth23 uplink from cctv network, bridge port pvid 9
sfp2 link to second crs, default bridge port pvid 1, tagged in bridge vlan with vlan id 9
eth24, eth23, sfp2 are ports of same bridge, bridge with vlan filtering enabled and pvid 22
second crs:
eth24 uplink from same management network(but another location), bridge port pvid 22
sfp2 uplink from first crs, default bridge port pvid 1, tagged in bridge vlan with vlan id 9
eth23 untagged port for cctv network, bridge port pvid 9
eth24, eth23, sfp2 are ports of same bridge, bridge with vlan filtering enabled and pvid 22
The only issue here is that something is causing a network loop or something like that because on second crs from eth23 i can't ping the cctv network while management link is up on eth24, disconnecting the link on eth24 and voila i can ping the cctv network.. why is this happening?

Could anyone please give me a hint on this? Is there something that i've misconfigured? Is something related to routeros?
Thanks.

Please make some type of diagram. That might help you and us to reason about it.

Thank you for the tip, main scheme would look like this https://drive.google.com/file/d/1YGyDD- ... Na9X7/view
First time i've tried with no vlan for management network, now with vlan for mgmt network situation is the same.
