While an OSPF daemon may stop advertising the affected route to its neighbors, the kernel will still have the route installed and thus the box won't be able to contact other hosts on the connected net, while they are reachable via alternate pass. I've checked that Cisco routers remove route from FIB when interface link goes down. I haven't checked Junipers yet. >From my viewpoint, removing route (or marking it unusable) is a correct behavior for router. Not sure it is correct for desktop. My vote is that we should implement this functionality and make it switchable via sysctl. I'd leave the default as is. What is opinion of other networkers? -- Totus tuus, Glebius.
