Transferring our Wan Fibre connection from a Cisco 4300 over to our MX84. We setup the static info to our WAN2 connection - WAN1 is utilizing our cable line at the moment - when adding the VLAN tag for the Metro Fibre, it causes the connection to not show at all in Uplink, and if we remove the VLAN tag, the connection is then visible but goes into Failed status. We've duplicated the subnet & mask currently being used on the 4300 router so not sure what we're doing wrong here. ISP has a device at dmarc that converts the fibre to ethernet and has a line running up to our suite and terminating at patch panel.
