I am trying to setup a redundant , High available OSPF network. Pls see attached.
The switches are also running OSPF instances with Routers, on both Primary and Seconday path. Do i need to setup OSPF peering between switches also (over the trunk) so each switch will have both different costs routes, in case 10 is not available it will install 100 in the routing table.
Or any other idea/suggestion will be helpful in desing a full redundant network.
