-It's an added flexibility built on top of virtual network peering, where users get an option to choose specific subnets that need to be peered across virtual networks. User can select or is prompted to enter the list of subnets across the virtual networks that they want to peer. In contrast, if regular virtual network peering, entire address space/subnets across the virtual networks get peered.

 Also, **a given peering link type cannot be changed**. That means, if there's a virtual network peering between virtual network A and virtual network B, and user wants to change that to subnet peering, the existing virtual network peering link needs to be deleted, and new peering needs to be created with the required parameters for subnet peering and vice versa.
 
-1. **Number of subnets that can be part of a peering link should be less than or equal to 200.**
-    - For example, in the VENT A and virtual network B peering link (illustrated by blue arrow headed line), total number of subnets participating in the peering here's 4 (two from virtual network A and two from virtual network B side). This number should be <=200.

 1. In the present release (Public preview and GA March 2025, feature remains behind subscription flag), **forward route from non-peered subnet to peered subnet exists** - that is, in the current scenario virtual network A and virtual network B peering, even though Subnet 2 from virtual network A side isn't peered, but it will still have route for Subnet 1 and Subnet 2 in virtual network B.
-    - To clarify more, in the subnet peering for virtual network A and virtual network B, customer would expect only Subnet 1 and Subnet 3 from virtual network A to have route for Subnet 1 and Subnet 2 in remote VENT B, however, Subnet 2 and Subnet 4 (from local side virtual network A which isn't peered) also have route for Subnet 1 and Subnet 2 in remote side (virtual network B), meaning the nonpeered subnets can send packet to destination node in the peered subnet, although the packet gets dropped and don't reach virtual machine.

 1. Subnet Peering and AVNM
     - Connected Group<br>
     If two virtual networks are connected in 'Connected Group', and if Subnet peering is configured over these two virtual networks, subnet peering takes preference and the connectivity between nonpeered subnets gets dropped.
     - AVNM Connectivity Configuration<br>
-    AVNM today can't differentiate between virtual network peering and Subnet peering. So let's say if Subnet peering exists between virtual network A and virtual network B, and later an AVNM user tries to establish a virtual network peering between virtual network A and virtual network B through some connectivity configuration (say Hub and Spoke deployment), AVNM would assume that peering between virtual network A and virtual network B already exists and would ignore the new peering request. We recommend users to exercise caution in such conflicting scenarios while using AVNM and Subnet peering

 ## Next steps
 
 Subnet peering helps you have better conservation of IPv4 space, by letting you reuse address spaces across subnets that need not be peered. It also prevents unnecessary exposure of entire virtual network address space through gateways to on-premises environments. With IPv6 only peering, you can further configure peering over IPv6 only for dual-stack subnets or IPv6 only subnets. Explore these capabilities and let us know if you have feedback and suggestions here. Your feedback on the overall feature would help us make Azure networking more powerful and enabling!

 Gateway transit is a peering property that enables a virtual network to use a virtual private network or an ExpressRoute gateway in a peered virtual network. Gateway transit works for both cross-premises and network-to-network connectivity. Traffic to the gateway (ingress or egress) in the peered virtual network incurs virtual network peering charges on the spoke virtual network (or virtual network without a VPN gateway). For more information, see [Azure VPN Gateway pricing](https://azure.microsoft.com/pricing/details/vpn-gateway/) for VPN gateway charges and ExpressRoute gateway charges.
