40G doesn’t have potential hashing problems that 4x10G does, bundles means potential drama with protocols on some boxes. Less of an issue on MX which is… generally pretty good with these things, but who knows what the other end hardware is. 4x10G discrete services (i.e. not a bundle) means you’ve likely still got balancing problems. 40G is easier to send over a single pair between DCs, too - 4x10G means muxes or similar. 40G works the same way of course, but does it in the optic. -- Nathan Ward _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
