Can someone comment on the attached OSPF design plan. I have OSPF running at 4 locations.
Each locations have 2 WAN links from different ISP's on separate router.
Locations A, C & D should point to locaion B as the default gateway. Is this design correct?
Do I need to enable OSPF on the LAN segment of location A,B & C? Is it going to crete any routing loops?
Please keep fault tolerance and load sharing in mind.
