paolosalvatori Thank you for the reply,
Im aware how it works and can be achieved at the end of private endpoint. Now im interested how something similar can be achieved at the other end where Private Link Service is.
According to "When configuring Azure Private Link service, the explicit setting privateLinkServiceNetworkPolicies must be disabled on the subnet. This setting only affects the Private Link service." From my understanding this limits options of routing traffic from Private Link Service. The only possible option might be AGW next Private Link Service where i can apply UDR to AGW subnet.
I follow Adam`s channel which is great source of learning. If you notice i wrote him comment below exact same video with the hope he can reply as its not documented scenario.
