STP really stops at the 1st L3 device (router). When a router holds a route, it really isn't concerned with anything other than what interface to use to send packets to. STP is a L2-L2 protocol that ensures that a L2 ennvironment is loop free.
If a packet from R1 needs to get to a host on SW2, R1 only knows what interface to send it to. STP then guides the L2 path of the packet.
They do both play roles, but they have limited dependencies.
I believe this is only true in some mls networks. If only L3 interfaces are interconnected, that is routers, then STP plays no role, because packet forwarding is based on L3 addresses and not L2 addresses.
my understanding is L3 converging has nothing to do with L2 converging. L3 activity based on L2 which provide links. So L2 convergen first, then there is a network, then L3 begin to calculate its route on this convergened network.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
