consider the diagram below
webserver ---- R1
R2
R3
user
say the user is trying to access the webserver. My question is what would be the destination address when the packet arrives at R2. Will the destination address be of R1 or the webserver itself .
I know that its a silly question
let me know the answer

The Layer 3 (i.e. IP address) destination address of the packet remains unchanged (i.e. Webserver's IP address) throughout the path, while the Layer 2 (e.g. MAC address) destination address changes hop-by-hop.
.......... User ---> R1 ---> R2 ---> R3 ---> Web server
Src.IP ...... User .... User .... User .... User
Dst.IP ...... Web .... Web .... Web ..... Web
Src.MAC ... User ..... R1 ...... R2 ........ R3
Dst.MAC ... R1 ........ R2 ...... R3 ...... Web
