Shared peerings in AWS Cloud WAN
Shared peering allows you to establish peering connections between your Cloud WAN core network and transit gateways in the same AWS Region. You can dynamically exchange routing and reachability information between your core network edge and transit gateway over these peering connections, and interconnect your existing transit gateway-based network with your Cloud WAN network. You can create a new transity gateway policy table for this new shared peering or you can choose an existing transit gatewa policy table to use.
When a core network owner shares their core network with your account, you are then able to create new peerings for the shared core network, delete existing peerings, or manage the tags associated with a peering. When you create a shared peering you can choose the core network that you want to associate the peering with, the edge location, and any transit gateways you want to share in this peering. In addition, you can also choose whether to create a new policy table for the shared peering or to use an existing policy table. If you choose an existing table, you'll be prompted to supply the transit gateway policy table to use.
