Network configuration

APEX Cloud Services with VMware Cloud delivers a comprehensive, high performance and resilient networking solution for your

SDDC.

The APEX Cloud Services with VMware Cloud networking solution includes:

● Top of Rack switches which provide redundant Layer 3 uplinks into your data center network.

● VeloCloud SD-WAN appliances provide secure connectivity into cloud management system of APEX Cloud Services with

VMware Cloud, enabling 24x7 monitoring and telemetry capture.

● Software Defined Networking within the SDDC powered by VMware NSX-T.

During the ordering process in the APEX Console, configure or select the following. If the configuration details are gathered ahead of time in collaboration with your network operations team, you can speed up the configuration process. Each of these items is discussed in detail below:

● Cloud operations network

● SD-WAN IP settings

● SD-WAN physical connectivity

● SDDC management network

● Out of Band (OOB) management network

● Local eBGP Autonomous System Number (ASN)

Note the following considerations:

● You cannot change the configurations after you complete the ordering process. Ensure that these network configurations are accurate before placing the order.

● The subnets are configured in Classless Inter-Domain Routing (CIDR) format. CIDR is an IP addressing scheme that replaces the older system, and which is based on classes A, B, and C. A single IP address can be used to designate many unique IP addresses with CIDR. A CIDR IP address looks like a normal IP address except that it ends with a slash followed by a number, called the IP network prefix. For example, you can express the idea that the IP address 192.168.0.1 is associated with the netmask 255.255.255.0 by using the CIDR notation of 192.168.0.1/24. In this case, 24 represents the number of network bits in the IP address. IPv4 address has 32 bits, so the network can be between 0 and 32.

Prerequisites

● Ensure that an existing network that can handle multiple subnets are available at the SDDC location.

● Ensure that a router with Internet connectivity to which the rack can be connected is available at the SDDC location.

● Ensure that you provide the underlay networking details for the uplink network to establish a connection between the SDDC and your network.

● Ensure that the vCenter Management IP (assigned from the SDDC management network supplied at order) reaches vcsa.vmware.com

through FQDN on HTTPS port 443. This communication does not go through proxy servers and establishes directly.

● Ensure that you update any firewall rules to allow traffic to vcsa.vmware.com

if you have set firewall rules.

● Ensure that the vCenter Management IP (assigned from SDDC management network supplied at order) can reach connect.hcx.vmware.com

and hybridity-depot.vmware.com

on the HTTPS port 443 if you plan to activate and deploy HCX. This communication establishes directly through your uplink connection and does not go through proxy servers.

Ensure that you update any firewall rules to allow traffic to the connect.hcx.vmware.com

and hybriditydepot.vmware.com

sites.

NOTE: hybridity-depot.vmware.com

is a CDN backend with a dynamic IP and therefore, you must configure it appropriately.

10 Network configuration

Cloud operations network

This is the IP address subnet for accessing the Cloud network corresponding to your region. The Org Cloud Management

Network is a /24 subnet. There is only one Org Cloud Management Network for an organization per region irrespective of the number of SDDCs you order in that region.

NOTE: This subnet should not be in use within your network and not be routable from your network.

The Org Cloud Management Network is a dedicated AWS Virtual Private Cloud (VPC) network, which is used for automated life-cycle management and monitoring. The Dell Site Reliability Engineers (SRE) use this network for life-cycle management, monitoring, and troubleshooting.

SD-WAN IP settings

A pair of SD-WAN VeloCloud devices is part of the SDDC rack. The VeloCloud SD-WAN network establishes an encrypted tunnel to connect securely and manage the APEX Cloud Services with VMware Cloud SDDC. You can assign the IP address through static or DHCP. If you are using static IP addressing, you must provide a single IP address that can route to the

Internet.

Your firewall must allow traffic through the ports, TCP 443 and UDP 2426, and establish a tunnel from VeloCloud to secure

VeloCloud gateways on the Internet. VeloCloud should have access to the DNS IPs 8.8.8.8 and 8.8.4.4 on the UDP port 53.

If you are using the URL filtering module in an L7 firewall, you must add the following URL firewall allowlist: https://vco129usvi1.velocloud.net/ .

The following is a list of IP addresses for VeloCloud Gateway and Orchestrator services. Your organization is set up under one

VeloCloud Orchestrator Service and one VeloCloud Gateway service IP. The applicable IP addresses should be added to your firewall IP allowlist. You can request your Dell deployment planning team to provide you with the Orchestrator and Gateway

Services IP your organization uses.

IP Address for VeloCloud Orchestrator Services:

● 54.173.111.227

The following VCG IP addresses are specific to VCO129 (54.173.111.227):

● 159.100.160.124

● 159.100.163.125

● 104.193.28.146

● 104.193.30.164

● 192.40.64.172

● 104.193.29.175

● 159.100.165.113

● 18.167.45.121

● 15.228.2.144

● 52.194.15.47

● 64.186.27.35

● 159.100.175.37

● 159.100.171.38

● 159.100.173.40

● 64.186.25.43

● 64.186.27.44

● 64.186.25.51

● 216.221.31.57

● 216.221.27.66

● 216.221.25.77

● 216.221.29.89

● 159.100.168.106

● 159.100.164.106

● 104.193.31.106

● 159.100.161.124

Network configuration 11

Static: Select this option to provide an IP address that is manually configured on the cloud-facing interfaces of the VeloCloud devices. Provide the following details:

● IPv4 address

● IP address prefix

● IP gateway

DHCP: Select this option to allow your network to assign an IP address dynamically, which is configured by default on the cloud-facing interfaces of the VeloCloud devices.

You can also select if you want the connection to your Internet router to be 1 Gb Copper (1000baseT) or Optical (1000baseSX).

NOTE: You must provide the cabling and the optical transceiver or copper connection in your router.

SD-WAN physical connectivity

This is the selection of physical network interface from SD-WAN VeloCloud devices to your internet router; 1Gb copper

(1000baseT) or 1Gb selection of physical network interface to your internet router; 1Gb copper (1000baseT) or 1Gb optical

(1000baseSX).

SDDC management network

The SDDC Management Network is a minimum /24 CIDR block, which must be routable in your network through uplink from the SDDC. This network is used for VMware ESXi management interfaces, vCenter Server, NSX-T and such other related virtual appliances.

Customers who plan to expand their environment beyond one rack in the future should supply a /23 CIDR block for the SDDC management network when ordering the initial single rack SDDC.

Out of band management network settings

The Dell SREs use the out-of-band management network for troubleshooting by connecting directly to the out-of-management ports of all hardware components in the rack.

NOTE: This subnet should not be in use within your network and not be routable in your network.

The size of the subnet mask is /24.

Ensure that the out-of-band management subnet that you provide here is not already in use on your network.

Top of rack (ToR) uplink configuration

An APEX Cloud Services with VMware Cloud SDDC has two ToR switches. Based on L3 Equal-cost multipath routing (ECMP), uplink connectivity establishes a connection between the ToR switches and your network. This configuration takes place during deployment by Dell Technologies Services and may be changed at a later time by submitting a Service Request through APEX

Console.

You can set up one or two uplink connections per ToR switch (if you select Dynamic/eBGP routing, only one uplink per ToR).

The bandwidth of each uplink connection can be 10 Gbps or 25 Gbps. Both the SFP+ (10 Gb) and SFP28 (25 Gb) fiber modules are prepopulated in the ToR switches.

NOTE: The customer is responsible to provide the fiber optic cables between the ToR and their network as well as transceivers for their switches and routers.

The following information will be collected by the Dell Technologies Deployment Planning team Services during the site planning process.

● Select if you want to use Static or Dynamic (eBGP) Routing.

● Select 10 Gb or 25 Gb connectivity and if two or four ports (four ports are only available with static routing).

12 Network configuration

● Configure IP addresses for ToR uplinks and corresponding customer core router in the following format: IPv4 address/prefix.

For example, 172.16.21.1/30.

● If using eBGP, configure local (ToR) and remote (customer router) Autonomous System Number (ASN) and Community.

○ Local ASN (ToR): Enter a local ASN to be configured for ToR.

■ Enter any private ASN using 2 bytes, 64512–65534 or 4 bytes, 4200000000- 4294967294, and specify the same local

ASN for ToR 1 and ToR 2. However, the local ASN should be different from the remote ASN.

○ Remote ASN (Upstream customer router): Enter a remote ASN for the upstream network.

■ You can enter any private ASN using 2 and 4 bytes, 64512–65534 and 4200000000- 4294967294 respectively. The remote ASN should be different from the local ASN.

○ Community: Enter a community value to manage the routes. ToR advertises the routes with this community value.

■ The community value format is a set of two 2 or 4-bytes numbers separated by a colon. Consider the following examples:

Community value for 2 bytes ASN: ToR 1, Local ASN:100 and ToR 2, Local ASN:200.

Community value for 4 bytes ASN: ToR 1, 65000:100 and ToR 2, 65000:200
