A question, i have Router A connects to Router B with 2 links, 1Gbps and 100Mbps WAN circuit. Both are running OSPF. Base on cost calculation, traffic vice-versa will traverse through 1Gb link and when it fails, it goes to 100Mbps link.
Will the traffic goes back to 1Gb link when the WAN circuit recover? I have an impression that OSPF will select a path with longer uptime with more stability.. (correct me if im wrong)
