To make the script work, I've made several additions to the ospf library, and also a small addition to ipOps. I've also considered to partially rewrite the ospf library using Lua native functions instead bin/bit, but I stopped because (maybe due to my poor Lua skills) I didn't found a convenient way to handle hex strings.
