Out-of-Band Management Network
7 Dell Technologies—VMware Cloud Foundation 4-node JumpStart Solutions Guide
1.1 Out-of-Band Management Network
Out-of-Band (OoB) management traffic for Management Modules (MX), iDRACs (Rack), and switch
management should be a simple flat network but there are no specific requirements for OoB management
networking.
1.2 Dynamic Routing
In the example environment deployed here, Border Gateway Protocol (BGP) was used in the upper layer
routing. NSX-T will be configured to exchange route information through BGP with the existing routers. While
BGP is not a mandate, it does simplify the deployment by eliminating the necessity to add multiple static
routes. Because the use of BGP is the recommended route, we will follow the BGP deployment path in this
example.
IMPORTANT—Before deploying the JumpStart Solution, review the guidelines and best practices described
in this section with your network team. Read the requirements and guidelines listed in the following sections:
• Network requirements for installing Cloud Foundation and SDDC Manager
• Additional Networks
• Network services
1.3 Network requirements for installing VM Cloud Foundation and
SDDC Manager
Cloud Foundation and the SDDC Manager require a minimum number of networks for a basic installation. At
least, the following four networks are required:
• Management network
• vSAN network
• vMotion network
• Host Overlay network
Jumbo frames or an MTU size of 9,000 is recommended on all VLANs. The minimum MTU value of 1,600 is
required for the "Overlay" networks.
