I have a doubt. I have seen in real time simulation in the packet tracer , where the router sends STP packet to switch. Does router really does that and can you explain since STP is for l2 domain only.

thank you in advance, Regards, Aps

Many routers can be configured as a bridge, with or without a virtual interface, so they run STP. It is configurable, so you can turn it off if you want.
