I am not sure if this or the switching forum is appropriate.  I am changing over from using a standard Cisco ios layer 3 switch as my core router, to using a Meraki layer 3 switch.  My question/need for help.  This core router does all my internal routing, but it also has a outside agency that has a direct fiber connection into my network, and its connected directly to this core router.  with Cisco ios I can configure that physical interface with an IP address, create an ACL, tie it to that interface, and create a route to channel allowed traffic between networks.   Moving now to using a Meraki Layer 3 switch as my core router for the network, how do i mimic this same process?  I don't see any where that i can tie an ip address to a specific interface on the Meraki layer 3 switch.   With that said my plan was to an actual Meraki MX device between the two networks, and use the MX device strictly to control traffic between the networks.  This is the more traditional approach, when you would ASA or PIX firewalls to control traffic between two physical networks.  Is that possible to setup and do in this scenario?   Thanks for any help. ...
