IP address assignment — customer facing networks

This section covers the guidelines when assigning IP addresses to customer facing networks.

Take into account the following when filling out the worksheet table in this section:

  • Data Center Uplink

    The data center uplink is the main data path of all northbound and southbound traffic in support of the ThinkAgile CP environment. This VLAN is customer defined and lives on the customer network. This network needs connectivity to the Internet (see Firewall Settings). It also needs a unique IP address and subnet across the ThinkAgile CP environment.

    • For dual interconnect configurations, you must provide one IP address for each interconnect switch and one IP address for the Virtual Router Redundancy Protocol (VRRP).

    • For single interconnect configurations, only one IP address is required.

  • OOB Interconnect network

    This network is used to manage the interconnect switches; it provides hardware health reporting and management between the interconnect switches and the cloud controller. This network needs connectivity to the Internet (see Firewall Settings). It also needs a unique IP address and netmask across the ThinkAgile CP environment.

  • Variable names

    Variable names are shown in italics in worksheet tables. Those names correspond to parameters that you need to specify when deploying the ThinkAgile CP solution (using the ThinkAgile CP Deployment Guide).

  • Network masks

    In worksheet tables, network masks must be entered in the Netmask or Prefix column using dotted decimal format X.X.X.X (for example: 10.1.1.2).

  • Network prefixes

    In worksheet tables, network prefixes must be entered in the Netmask or Prefix column in prefix format /<number of bits> (for example: /23).

The following are IP address assignment considerations for customer facing networks:

Note

  • The variables wan_ip1, wan_ip2, wan_vipand wan_gw must belong to the same subnet.

  • The variable wan_gw refers to the IP address assigned to the customer edge router attached to the stack’s interconnects via the data uplinks.

  • The variables oob_ip1, oob_ip2, and oob_vip must belong to the same subnet.
