VLAN and VxLAN configurations

HPE Telco Blueprints provide the following network configurations:
VxLAN (Virtual Extensible Local Area Network)

The switch configuration using VxLAN is automated or manual.

The following table lists the configuration modes for each switch:

VLAN Name RHOCP Network Description
iLO-OOBM Management iLO-OOBM network
OCP OpenShift Container Platform network OpenShift Container Platform network is used to:
  • PXE boot the RHCOS and RHEL machines

  • To provide the cluster connectivity between the master and worker nodes.

OCP is an untagged network.

Provider VLAN is a tagged network.

VxLAN configurations

The HPE Telco Blueprints provide a scalable solution to deploy and manage network functions and services using VTEP-capable switches over Virtual Extensible Local Area Network (VxLAN).

VxLAN is a network encapsulation mechanism that enables containers to be deployed on any physical hypervisor to allow multi-tenancy within the Data Center. Encapsulating container traffic in VxLAN tunnels solves the container mobility issue which requires the same layer 2 segment and overcomes network infrastructure MAC address and VLAN scalability limitations.

An HPE VTEP (Virtual Tunnel Endpoint) uses the VxLAN tunnel to provide VxLAN services.

VxLAN — It is a logical point-to-point tunnel between VTEPs over the transport network. Each VxLAN tunnel can trunk multiple VxLANs.
