Region properties

Table 1. Region properties
Property	Description
Name	Identifies this region uniquely within the Fabric Services System.
Description	Describes the region. This text is displayed in the Additional information panel for a region.
Location	Specifies the physical location represented by the region.
System IP Pool	Pool name: Specifies the name of the default System IP pool. This is set as "default" and cannot be changed.
IP Type: Specifies whether the IP addresses within this pool use IPv4 or IPv6 format. This is set as "IPv4" and cannot be changed.
IP Blocks: Contains one or more CIDR blocks representing IP addresses that can be assigned to the management interfaces of devices managed by the system. Enter these blocks using CIDR notation; for example, 192.0.2.0/24. If you need more IP addresses for devices in your fabrics than the current CIDR blocks support, you can modify the region to add more CIDR blocks to the System IP pool.
Inter Switch Link IP Pool	Pool name: Specifies the name of the default Inter Switch Link IP pool. This is set as "default" and cannot be changed.
IP Type: Specifies whether the IP addresses within this pool use IPv4 or IPv6 format. This is set as "IPv4" and cannot be changed.
IP Blocks: Contains one or more CIDR blocks representing IP addresses that can be assigned to inter-switch links between devices in real (not Digital Sandbox) fabric intents throughout this region. Enter these blocks using CIDR notation. For example: 192.0.2.0/24. Note: Each link within a fabric intent requires two IP addresses from this block; one for each endpoint. From the set of links that are possible with the IP addresses in the specified CIDR block, two are reserved for use by the system to represent the network IP address and the broadcast address. These are unavailable for inter-switch links. For example, a CIDR block ending in /26 that can support up to 32 links actually supports only up to 30 links within the fabric intents in this region. If you create a fabric intent that requires more links than are available with the current pool, fabric generation fails. The event log for the fabric intent indicates that there are insufficient IP addresses for the required links, and shows the number of addresses required versus the number available. If you need more IP addresses available to your fabrics than the current CIDR blocks support, you can modify the region to add more CIDR blocks and thereby support additional links.
Out of Band Management IP Pool	Pool name: Specifies the name of the default Out of Band Management IP pool. This is set as "default" and cannot be changed.
IP Type: Specifies whether the IP addresses within this pool use IPv4 or IPv6 format. This is set as "IPv4" and cannot be changed.
IP Blocks: Contains a CIDR block representing the IP addresses that will be assigned to the management interfaces of devices. Enter these blocks using CIDR notation; for example: 192.0.2.0/24. Note: From the set of links that are possible with the IP addresses in the specified CIDR block, two are reserved for use by the system to represent the network IP address and the broadcast address. These are unavailable for the out-of-band management IP pool. If you need more links in your fabrics than the CIDR blocks you specified here support, you can modify the region to add more CIDR blocks to this pool.
BGP ASN Numbers	Determines the set of Autonomous System Numbers (ASNs) available for BGP. The Fabric Services System can maintain a pool of ASNs consisting of multiple blocks of numbers. ASNs are used to uniquely identify a network with a unique routing policy. The ASN must be unique so that IP address blocks appear to originate from a unique location to which BGP can determine a route. The single pool of numbers is assigned the label "default", and this cannot be altered. Within the pool, you can define one or more blocks of contiguous ASNs by providing a start and end number for each block. ASNs can be any number from 0 to 4294967295. Blocks of numbers within the same pool cannot contain overlapping values. As one block of ASNs is exhausted, the system begins assigning values from whichever remaining, unexhausted block contains the highest available values. Even if some numbers from the first block become available, the system continues allocating numbers from this second block until the second block is exhausted. Then the system again looks for the block with the highest available values from which to allocate new ASNs, and so on. Start: the lowest permissible value in a range of a single block of ASNs.
Start: specifies the lowest permissible value within a block of ASNs.
End: specifies the highest permissible value within a block of ASNs.
Digital Sandbox DHCP Configuration	Digital Sandbox DHCP CIDR: specifies the CIDR block use to assign IP addresses for the SR Linux container nodes within the Fabric Services System Digital Sandbox. You can create both IPv4 and IPv6 CIDR blocks for use by Digital Sandbox fabric intents. For more information about the Digital Sandbox, see Digital Sandbox.
Route Target	Global Index: specifies whether services created as part of a workload are unique within a region and across multiple regions.
EVPN Profile	Control Plane: specifies the control plane type to use throughout the region. Supported values are: None: no EVPN peering eBGP iBGP Default value: None
Protocol authentication	BGP: Enabled or Disabled Determines whether the Fabric Services System should create a unique MD5 authentication key. This encrypted key is required to authenticate communication between eBGP peers. No user action is required to create the authentication key or to incorporate eBGP authentication requiring this key into subsequent node configurations. These actions are handled internally by the system.
EVI	Determines the range of the EVI pool: Start: the lowest value in the range of EVI values End: the highest value in the range of EVI values
VNI	Determines the range of the VNI pool: Start: the lowest value in the range of VNI values End: the highest value in the range of VNI values
