I am confuse

Hi,
Suppose we have below diagram,

PC1 <

---

> SW1 <

---

> R1 <

---

> SW2 <

---

> PC2

Each PC1 and PC2 is in different subnet, PC1 need to send data to PC2, and I now if they are in different subnet PC1 send data to default gateway (R1), and after that R1 check the destination address in route table for (R1) and forwarded to PC2.

My question is, when data forwarded from PC1 to default gateway did IP address for destination (PC2) change to be IP address for default gateway or it is internal processing done by OS and destination address for PC2 still not changes.

BR,

PC1 would ARP for the default gateways MAC address then send the data with the destination IP address of PC2 and the destination MAC address of the gateway.

Great thank for your clarification

Took me ages when I was studying CCENT to understand this even though I had seen it a thousand times before. once you understand this, it makes the whole process so much easier to understand.
