How to connect 2 MX on a 2 MS CORE Switch without aggregate ?

Hello,

 

I would like to do this configuration:

 

Diagramme sans nom.jpg

I have 2 MX for Wan redundancy, and a CORE STACK with 2 MS.

I need a trunk between the MX and MS because MX does inter-vlan routing.

How can i connect the stack to the 2 MX without creating a loop, because MX doesn't support aggregate ?

 

Thanks

Trunk all ports with the same vlans to the switches.  Make sure the switches have the spaning-tree protocol  enabled on the ports to mx/other swtiches

If you cable the topology this way, it will work but spanning tree will disable one of the ports in order to prevent a loop (the MX will pass along the bpdu's).

The 2 differents MX ports have the same MAC address ?
