L3 OVL - Manage vSG
Layer 3 Configuration - Manage vSG
There are features and functions used in Arista NetVisor UNUM and Insight Analytics that are common throughout the user interface (UI). Please refer to the Common Functions section for more information on the use of these functions and features.
Configuring Virtual Service Groups
In the following scenario, there are, for example, two tenants who share a common service.
The three network entities are associated with three VRFs, respectively:
•TENANT-GREEN
•TENANT-GREY
•SERVICE-AMBER
All three VRFs need to share at least one subnet with the others for proper connectivity.
This configuration is an any-to-any communication model, in which you can use the promiscuous keyword to (explicitly) state that sharing is allowed. Then you can specify which subnets are shared.
For example, TENANT-GREEN and TENANT-GREY share one of their subnets with SERVICE-AMBER.
