Hi, I noticed that the multipath support in OSPF seems to be fairly limited. Essentially I was only able to make it do multipath if I had two interfaces connecting to the same router. At my company, we need true multipath between multiple routers using a single interface. (If I needed the other, I could use LACP) I am aware of the implications the default multipath implementation in Linux which operates on a per-packet basis, which is why we've patched our kernels to do it per-flow instead. Anyway, I seemed to have managed to make multipath work as expected - at least in our setup. (Patch attached) Essentially, I've hooked my multipath code into ri_install_ext() and ri_install_net(), where I add the equal routes if the routes share the same type, metrics and OSPF area. I realize that my add_nexthops() is /very/ similar to merge_nexthops() in functionality, but it seemed that the top_hash_entry() could be null, so I wrote a new method which did not rely on that - at the cost of more calls to copy_nexthop(), I guess. Any thoughts? Best regard Peter Christensen
