If we are talking about simple networks, then probably actual SPT out-come would be same by having same metric in every link (i.e. make distance vector out of your link-state, (essentially what RFC7938 topologies would be). This would be simplest possible metric design. > (I am myself running a mostly DC network, with a little bit of campus > network on the side, and we use bandwidth-based metrics in our OSPF. > But we have standardized on using 3 Tbit/s as our "reference bandwidth", > and Junos doesn't allow us to set that, so we set explicit metrics.) And you have shorter paths with inferior bandwidth which you do not want to use, you'll rather take 9x10GE links than 1xGE to reach the destination? It boggles my mind which network has _common case_ where bandwidth is most indicative of best SPT. -- ++ytti _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
