-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Everyone,
I have raised this topic before (to little avail), but it seems with the existence of the multi-provider extension in Neutron and the upcoming scalability improvements in the K release along with the migration script(s), I might wish to move to Neutron from Nova-Network quite soon. The issue is that I have a network in which only certain IP subnets are available to certain compute nodes. Say for example Rack A only has access to 192.168.0.0/24 whilst Rack B only has access to 192.168.1.0/24. It would be useless (if not frustrating to the user) to have an instance scheduled, receive a port only to find that the instance was scheduled on a compute node somewhere in Rack A, but the port assigned to it has an IP address in the subnet 192.168.1.0/24. With the multi-provider networks, is it possible to create an L3 segment composed of multiple L2 segments, or is such functionality possible otherwise? I can foresee some sort of mapping of subnets on agents much in the same way as physical network mappings on those machines, or some sort of "meta network" whereby a single network can be composed of multiple other networks. The issue is that I have multiple racks in different subnets, and VLANs (currently) can't be exposed to the compute nodes, and even if they were I'd have the headache of again restricting subnets to specific segments. Is anyone running such a system with Neutron in a production environment (I'm running such a system with Nova-Network), or is there an actual use case for this, and if so what is the best approach? Thanks, Joe -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBAgAGBQJTxTweAAoJEHYEICnOV08jZIgQAOQbkCSWj1jvIj+NMIopEs/s itDG6QeY18NQky5mAiFr9ejPUtQVKovQmDyvA1NpwtKqRcBBM87znWg5UnWO2nwG 19JQjfrjhOHaQiNqcrYZdcIFSxqcxL9K9dkQcp1FIyMxWuCTEgHtrQ9/reYodoeW ABBxfp5Vo1oF+ib7fHJo9pCw83wCE/gpsjzcfNeAirvjBjM0JZSrf+IJXL7bn5Gp bmYMnVvFLaR7kkCoQk5vuVOf1+f17DERyKHzQ38JkUUM/BYg6rfavDDzeXi9eKl2 piOE4A2QSrIUeN4HpOkCp1mHYvkIqsOzaWRluJ6eKZRchFkKioTCcxLbznoK5RIm X6tq+cPLMHNxUQ6b5JDWOKpbTbsmOgRFQn6XsHIFxFg5/+k5I8B1vV2mmECAZhgl 1bGf8ec6igUYKYqyNVP/b/XoccryTOr4b/i5UeDSRLq0hC9Kxa/jwBAvcZ181iMk /AwHA5iaI6BFVS5WzE4G570ZVEZezVAQC7ah7Za5OWUXqgGR5a3yr6UdG1tIWyNw 1Exl/FcvQY5PvPxhV2bK6feR/369E4lcG7MKiBkpEl/KKVt+a5JEIAHECOOEqnzX mt8CW9pLUkolNfdBZl3u130Y77OA74RR9EAgV42zZmKWA2r4GnWTu5wn8v2VAOzG FDLf+j92m6zUalcIG3sq =U88f -----END PGP SIGNATURE----- _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : [email protected] Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
