I am researching an configuration for our Palo-Alto 850 firewalls. We currently have 4 ISP routers coming into our facility (1x MPLS/Fiber, 1x cable and 2 DSL). We would like to connect these to a L3 switch so we can setup vLans and from there run a fiber to our PA-850 HA set. Is it possible to create 4 virtual routers on the PA and assign each a route to a specific vLan/ISP router.
I have researched the PA documentation and it lists a multiple ISP option up to 2 connections but specifically configured for connection failover, not for just separating traffic streams based on source/target vLans.
