MX84 Fibre Wan setup

[DJefferson]

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.

The  configured  IP address  can  reach  the internet?

[DJefferson]

Yes sir. Connected to the Cisco router everything is running great. When we move the cable to the Meraki we fail.

[DJefferson]

Disregard. We just learned our 3rd party provider has BGP setup on the dmarc device so we'll now switch gears and start researching if MX84 is capable of performing BGP Routing and if so, how to set this up. 🙂 thank you

You can get support to enable BGP by logging a ticket, but I'm not sure how fully featured it is.  I believe it is better than the OSPF listen only routing.

What was the config at the 4xxx?

Did you check  the next  hop if  it has the correct  arp  entry, meraki  mac+ configured ip .

Does the provider block/filter any traffic related to this  test? https://documentation.meraki.com/MX/Firewall_and_Traffic_Shaping/Connection_Monitoring_for_WAN_Failo...

The MX84 can not do BGP for this case.

[DJefferson]

Yeah, that's what we found. MX appears to only perform BGP in one armed concentrator, which turns it into layer 2, which we can't use. we're looking at other options. thank you everyone for your quick replies
