Hi, folks I'm trying tacker to start some service VMs as Service Function VNF by "heat" tenant user, service VMs have special Neutron net & subnet, other common tenant VMs will have their own Neutron net & subnet, my question is how to route the traffic to service VMs in Openstack environment, DVR or router?
I integrated Opendaylight and used Opendaylight ML2 driver (https://github.com/openstack/networking-odl), in that case, I used its L3 routing plugin instead of Neutron L3, I also integrated ovsdb, from ovsdb perspective, ARP response and L3 routing are done by openflow tables, so can openflow tables do the same thing to routing the traffic between tenant VMs and service VMs? Network topology looks like the below diagram. +--------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Compute Node 1 | |Compute Node 2 | | | | | | | | | | | | | | | | | | | | | | +--------------------+ +---------------------+ | | +--------------------+ +-----------------+ | | |Tenant VM1 | |Service VMx | | | |Tenant VM2 | |Service VMy| | | | 10.0.0.3 | | 11.0.0.3 | | | | 10.0.0.4 | | 11.0.0.4 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | +-------eth0-------+ +--------eth0------+ | | +-------eth0-------+ +------eth0-----+ | | | | | | | | | | | | | | | | | | tap0 tap1 | | tap0 tap1 | | | ovs | | | | ovs | | | +-------------br-int------------+ | | +------------br-int------------+ | | | | | | | | +----------------+---------------+ | | +----------------+---------------+ | | | | | | | | | | VxLAN1 VxLAN-gpe1 | | VxLAN1 VxLAN-gpe1 | | | | | |-------------------------------------eth1---------------------------------+ + ---------------------------------------eth1-----------------------------+ 192.188.50.3| | 192.168.50.4 +===========================================================================+ __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: [email protected]?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
