Edit: While Mikrotik is well known for their consumer-grade wireless routers, this question is about their rack mounted, carrier-grade, aggregation service routers.
I need to send a VLAN trunk over an EoIP tunnel through two RouterOS/Mikrotik routers. I have thus bridged an ethernet interface on each side of the link with the respective EoIP interfaces.
Seeing how different VLANs and trunks are handled on RouterOS makes me wonder how I should go about this.
The frames will be tagged on egress from Catalyst switches on either side of the routers. Can one simply skip any VLAN configuration on RouterOS in this case? Will it bridge the frames with 802.1q tags intact?
I assume that such configuration will cause the IP addresses of the routers to be accessible from any VLAN on the trunk, if any addresses are configured on the bridged ethernet interfaces.
Any other downside to this configuration? Is there a better way?
