    Hello @CK Yamazake-Pat ,

    Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

    Coming to your query, yes, VNET A's Virtual Network Connection can propagate peered VNET B's address space to the Virtual Hub's Route table.

    Virtual WAN allows transit connectivity between VNets. Transit connectivity between the VNets in Standard Virtual WAN is enabled due to the presence of a router in every virtual hub.
    Please refer : https://learn.microsoft.com/en-us/azure/virtual-wan/virtual-wan-about#transit

    Standard Virtual WAN supports VNet-to-VNet transitive connectivity via the Virtual WAN hub that the VNets are connected to.
