routing local traffic via internet port

[kfat]

I have MX 450 connected to a switch port and the switch is connected to a router. The router has 3 interfaces, 2 MPLS and one local internet connection. for now, my Meraki traffic goes via the MPLS circuits cross to the DC. The configuration on the router is so long otherwise I will post it in the forum. any idea how to reroute the traffic to go via local internet instead. Example router map or ACL?

Thanks

you can attach your routers config as a file instead of paste all text

it depends on how other traffic through the MX450 flows 
if the MX450 is only for internet access (no traffic to corporate network), then you can
- create a new vlan on the switch 
- attach your MX450 to this vlan
- create a router (sub)interface for this vlan
- and configure your router that all traffic from this vlan goes to internet (no route-maps needed)

if you do use the MX450 also for the corporate network
then you may create a new SSID, that is drops it packets onto the vlan created above
