Description: Use the traceroute command to map the IP addresses that a packet travels through to get from one device to another
Instructions:
1. Configure routers to the specification given below
2. Enable RIP routing across all three routers
3. From Router1, ping the directly connected routers and their interfaces which are Router2 ethernet0 and Router3 serial 0
4. You should be able to ping non-directly connected routers as RIP routing is enabled
5. Next , the traceroute command is entered which helps in determining the path of a packet to its destination.
