Hi I have this scenario where I have four vrf interfaces delivered by my ISP router in access mode.
I initially intended to connect those interfaces to my Dell PowerConnect 6248 so that I can handle the networks delivered myself. But then I realized this Layer 3 switch does not support having multiple default routes, one for every VLAN connected to the VRF interfaces on the ISP router.
So I'm planning on using an ASA 5520 that I have laying around and put it between the ISP router and the PC6248 so it can handle the routing of the different interfaces. As far I can see I can set a default route on an interface and a second default route on another interface as long as they have different metrics, but I don't know if this will work well or at all.
