A Network defines the rules that determine which IP addresses to use for Teradata Fabric communication. Rules can be defined using Classless Inter-Domain Routing (CIDR) notation or by matching interface names. Networks are referenced by links and there is an initiating network and target network for each hop. When no network is selected, the data analytics Fabric tries to establish connections in parallel using all available networks. The Fabric selects the first network that succeeds in establishing a connection.

Enter the interface name.
You can add multiple matching rules by selecting

to remove rules.Use load balancer address Select for a network connection through a load balancer. Instead of connecting to individual node IPs, connections are made using the load balancer address or hostname. No ingress Select No Ingress when you do not want to have direct network connections or when bi-directional connectivity is not available. Nodes behind the network must poll for connection requests and establish connections in reverse. See Add No Ingress to a Network. - CIDR notation
