Egress groups organize the presentation of egress traffic from your cluster on the network map. You define egress groups for your clusters based on domains and IP addresses.
There are two default egress groups: public and private. Public egress contains the traffic that goes outside of your network. Private egress comprises the egress traffic that uses a private address space of IP addresses.
Note: If a destination classifies for two or more egress groups, the traffic appears under the most specific egress group.
