I'm setting up a new branch office very similar to the one shown in the attached diagram, and wanted to run it by you guys before buying any equipment.
My two questions are:
1. What's best way to link the layer 3 switch and the router? Should I use a /252 subnet mask so the link has it's own subnet, or use a trunk and sub-interfaces?
2. Would it be best to use OSPF on the layer 3 switch, or just a default route to the router; then just use OSPF on the router?
