Hi Folks, I have a customer build where we need to uplink the MX 250 appliances to the Cat9k. Both sides is a trunk port. The "internet port" on the MX will be connected to the Cat9k. How can I create 2 X subnets on it so that one of them is an incoming vlan to the MX and the other outgoing vlan? Say vlan10 in the incoming vlan, so the Cat9k has a default-route to the MX on vlan10, and then the MX has a default-route on vlan20 towards the upstream ISP going via the same Internet uplink.
