Shared \(VLAN or Multi-Netted\) Ethernet Interfaces
|
||
|
|
===================================================
|
||
|
|
|
||
|
|
The management, |OAM|, cluster host, and other networks for container workload
|
||
|
|
external connectivity, can share Ethernet or aggregated Ethernet interfaces
|
||
|
|
using |VLAN| tagging or IP Multi-Netting.
|
||
|
|
|
||
|
|
The |OAM| internal management cluster host, and other external networks, can
|
||
|
|
use |VLAN| tagging or IP Multi-Netting, allowing them to share an Ethernet or
|
||
|
|
aggregated Ethernet interface with other networks. If the internal management
|
||
|
|
network is implemented as a |VLAN|-tagged network then it must be on the same
|
||
|
|
physical interface used for |PXE| booting.
|
||
|
|
|
||
|
|
The following arrangements are possible:

- One interface for the internal management network and internal cluster host
|
||
|
|
network using multi-netting, and another interface for |OAM| \(on which
|
||
|
|
container workloads are exposed externally\). This is the default
|
||
|
|
configuration.
|
||
|
|
|
||
|
|
- One interface for the internal management network and another interface for
|
||
|
|
the external |OAM| and external cluster host \(on which container workloads
|
||
|
|
are exposed externally\) networks. Both are implemented using |VLAN|
|
||
|
|
tagging.
|
||
|
|
|
||
|
|
- One interface for the internal management network, another interface for
|
||
|
|
the external |OAM| network, and a third for an external cluster host
|
||
|
|
network \(on which container workloads are exposed externally\).
|
||
|
|
|
||
|
|
- One interface for the internal management network and internal cluster host
|
||
|
|
network using multi-netting, another interface for |OAM| and a third
|
||
|
|
interface for an additional network on which container workloads are
|
||
|
|
exposed externally.

For some typical interface scenarios, see |planning-doc|: :ref:`Hardware
|
||
|
|
Requirements <starlingx-hardware-requirements>`.
|
||
|
|
|
||
|
|
Options to share an interface using |VLAN| tagging or Multi-Netting are
|
||
|
|
presented in the Ansible Bootstrap Playbook. To attach an interface to other
|
||
|
|
networks after configuration, you can edit the interface.
