| + | ==== Brownfield approach with Meta Data Structure ==== | ||
| + | |||
| + | This will be more suitable for OPNFV 6-server POD usage with Jenkins Integration. As pointed by Iben Rodriguez of Spirent, most enterprise prefer to work with existing DC resources and hence Carriers need to support Brownfield vRouter in VM within existing DC resources. | ||
| + | |||
| + | Now we have an IP6VM (meaning a VM with two IPv6 Interfaces) and we need to downlaod and install Quagga base package(with just IPv6 add-on) to invoke and use it as a VRouter, rather than the OVS based in Hypervisor for switching and forwarding as usually done in OpenStack Neutron.Functionally the VM approach may have performance issues but lets deal with that latter as this gives better isolation and modularity for scaling. | ||
