Question
### Network Routing and ICMP Requests #### Diagram Summary The network diagram illustrates a scenario in which PC1 sends an ICMP ECHO request to PC2. The network is divided into two main subnets, each connected by routers R1 and R2. - **Network Subnet 1**: - PC1 (with IP 10.0.1.0/24) is connected to R1 through interface `f0/1`. - R1 has a loopback address of 1.1.1.1/32 and is part of OSPF Area 0. - **Network Subnet 2**: - PC2 (with IP 10.0.3.0/24) is connected to R2 through interface `f0/1`. - R2 has a loopback address of 2.2.2.2/32 and is part of the same OSPF Area 0. Both routers have DHCP services enabled to assign IP addresses dynamically to the connected devices. #### Key Network Elements: - **R1** is configured with interface ids `f0/0` and `f0/1`, and its MAC address is part of the test. - **R2** differentiates the network with an interface id `f0/0` connecting it to R1. #### Task Description The main task in this scenario is to determine which MAC address will be displayed when PC2 receives the ICMP ECHO request packet from PC1. #### Options for MAC Address: - **R1 f0/1** - **R2 f0/1** - **R2 f0/0** - **R1 f0/0** - **PC1** The handling of this scenario examines how data packets navigate through network interfaces based on routing and MAC addressing at each hop between the source (PC1) and destination (PC2). ### Understanding ICMP and MAC Address Display When PC1 sends an ICMP ECHO request to PC2, the packet must pass through routers that bridge their respective subnets. The MAC address displayed at PC2 upon receiving the packet depends on the final hop, which involves R2. In typical scenarios, the MAC address shown on such packets when received by PC2 is that of the last router interface it directly connects to, which in this case is likely to be `R2 f0/1`, completing the path navigation

Expert Solution
Step 1

For sending data packets from one system to another system, intermediate routers are used.

These packets contains IP addresses of source and destination and MAC addresses are changing point to point.

MAC address is 48 bit address which is provided by Data link layer.
