Looking for suggestions based on below requirements.
Current Network: LAN works on a single VLAN and router is the GW. Primary path is the MPLS, terminating on the router and secondary path is internet link , terminating on the FW. Router has a default route toward the MPLS link and another default route to internet link with higher AD value.A S2S tunnel is in place for remote site to DC/ Corp. connectivity over the internet link. All corporate internet traffic traverses via MPLS or S2S tunnel to Corp. office and exits from internet facing FW at the Corp Office.
We are going to introduce wi-fi across remote sites. I want to keep most of the routing in the router, ISR 4K.
Handheld devices will have certain applications installed and they will be accessing intranet as well as internet. I want internal traffic from these devices/ application to use MPLS as primary path and S2S tunnel as the secondary path. However, internet bound traffic from these devices/ application should access internet link as the primary and only path.
Attached current network
