is this the correct action a router takes when forwarding an ip packet

beginner_ccna

having difficulties with understanding the below as i dont think its correct-

is the below the correct action a router takes when forwarding an ip packet received on a lan interface:
1) checks the incoming frame's fcs
2) discards the data link header/trailer
3) matches the destination ip address in the header to the ip routing table
4) builds a new data link header
5) forwards the packet out the outgoing interface

i though routers didnt have nothing to do with frames as they deal with packets at layer 3 of the osi model

i personally thought, 1,2 and 4 were done at the data link layer by switches

please can someone clarify this?

That is correct. The router still has to be concerned with data link headers, it just doesn't (usually) make forwarding decisions based on them. If a router is forwarding a packet to a switch it has to put the destination MAC on there right? How else would the switch know where to send it?
