Understanding OSPF Routing (part 2) Oct 30, 2008, 06 :06 UTC (0 Talkback[s]) (2673 reads) (Other stories by Charlie Schluting)
"People have a tendency to tinker with traffic, even when they aren’t suffering from under-provisioned bandwidth. In OSPF, you cannot really influence the way traffic is routed, aside from adjusting a path’s metric. Some routers support making changes to weights, but this isn’t usually necessary. OSPF generally takes care of assigning weights, based on the speed of the interfaces on a router. You can also use ECMP (equal cost multipath) with OSPF, if you have two links to the same place and wish to load balance in a round-robin fashion. Don’t try tinkering with OSPF parameters; more likely than not, if you think you have a problem it’s a network design issue, and fixing that will accomplish your goals."
