An operator needs to configure a second Virtual Service that reuses an existing Virtual Service...

Avi Load Balancer supports sharing a single VIP across multiple Virtual Services when each Virtual Service uses a different service port. This is useful when multiple applications or protocols must use the same IP address but separate listener ports, profiles, pools, and policies. Broadcom documentation for sharing a single VIP across multiple Virtual Services describes selecting an existing VS VIP while creating another Virtual Service. This avoids manually typing the same IP address as a separate allocation, which could create duplicate or inconsistent VIP configuration. Creating a child Virtual Service is used for other use cases, such as SNI or parent-child designs, not simply reusing the same VIP on a different port. Therefore, the correct method is to use Advanced Setup and select the existing VS VIP.
