| # RHOSO Deployed Topology - BGP using kernel routing and OVN NB DB driver | ||
|
|
||
| ## General information | ||
| | Revision | Change | Date | | ||
| |--------: | :-------------------- | :--------------: | | ||
| | v0.1 | Initial publication | 2024-01-12 | | ||
|
|
||
| ## Node topology | ||
| | Node role | bm/vm | amount | | ||
| | --------------------------------------------- | ----- | ------ | | ||
| | Openshift master/worker combo-node cluster | vm | 3 | | ||
| | Compute nodes | vm | 3 | | ||
| | Networker nodes | vm | 3 | | ||
| | Ceph nodes | vm | 3 | | ||
| | Leaf routers | vm | 6 | | ||
| | Spine routers | vm | 2 | | ||
| | External routers | vm | 1 | | ||
| | External VMs | vm | 1 | | ||
|
|
||
| ## Services, enabled features and configurations | ||
| | Service | configuration | Lock-in coverage? | | ||
| | ------------------------------------------- | ---------------------------------------------------------------------------------------- | ------------------ | | ||
| | Neutron | ML2/OVN, DVR | Must have | | ||
| | Octavia | | Must have | | ||
| | OVN-BGP-Agent | kernel-routing, nbdb-driver expose-tenant-networks disabled, sync-interval default value | Must have | | ||
| | FRR | different ASN per rack, interface-level BGP peers | Must have | | ||
|
|
||
| ## Considerations/Constraints | ||
| 1. Virtual networks should be created to connect the VMs between them. | ||
| 2. All the VMs that are neither Openstack nor Openshift nodes need to be | ||
| properly configured in order to support the BGP protocol. | ||
| 3. The spine/leaf topology separates the overcloud nodes into different L2 | ||
| network segments, called racks. Each rack includes one compute, one | ||
| networker, one ceph and two leafs. | ||
| 4. A separate provisioning network is necessary to install Openstack on those | ||
| nodes. | ||
| 5. Once Openstack is installed on them, controlplane and dataplane connectivity | ||
| between them and with external machines (extvm) is achieved using the BGP | ||
| protocol. | ||
| 6. Tests are executed from the extvm machine, in order to verify external | ||
| connectivity. | ||
|
|
||
| ## Testing tree | ||
| | Test framework | Stage to run | Special configuration | Test case to report | | ||
| | ------------------------ | ------------ | --------------------------------------------------------------------- | :----------------------: | | ||
| | Tempest/neutron+octavia | stage 6 | skips due to usupported features (multicast, FIP port-forwarding, etc)| scenario | | ||
| | Tobiko/Faults | stage 7 | | sanity, scenario, faults | | ||
|
|
||
| ## Stages | ||
| All stages must be executed in the order listed below. Everything is required unless otherwise indicated. | ||
| 1. [Pre-deployment: create virtual networks, virtual routers and nodes](bgp-pre-deplyment.md) | ||
| 2. [Install the OpenStack K8S operators and their dependencies](../../common/) | ||
| 3. [Configure networking and deploy the Openstack control plane](bgp-control-plane.md) | ||
| 4. [Configure and deploy the initial data plane to prepare for Ceph installation](bgp-pre-data-plane) | ||
| 5. [Update the control plane and finish deploying the data plane after Ceph has been installed](bgp-post-data-plane) | ||
| 6. [Execute non destructive testing](bgp-tempest.md) | ||
| 7. [Execute HA testing](bgp-tobiko.md) |
