Usage

Use from Neutron API CLI

Example commands to use by the admin to create a BGPVPN resource:

neutron bgpvpn-create --route-targets 64512:1 --tenant-id b954279e1e064dc9b8264474cb3e6bd2
neutron bgpvpn-list
neutron bgpvpn-update 1009a0f326b6403180c18f3caa1430de --name myBGPVPN --tenant 4a75e08c45f14aa9afc5da081c9bb534

Example commands to use by the tenant owning the BGPVPN to associate a Network to it:

neutron bgpvpn-net-assoc-create myBGPVPN --network 828cddad3b834e79b79abc1b87b6cca0
# returns <net-assoc-uuid>
neutron bgpvpn-net-assoc-list myBGPVPN
neutron bgpvpn-net-assoc-show <net-assoc-uuid> myBGPVPN

neutron bgpvpn-net-assoc-delete <net-assoc-uuid> myBGPVPN

Use from Horizon

See Horizon.

Use from Heat

See Heat.

Use from Python

The BGPVPN API is dynamically loaded by Neutron. There is the same behaviour with the Python lib “neutronclient” use. This allows to programmatically handle BGPVPN resources as well as Network association resources and Router association resources.
