Q1. What is split horison? How can we resolve it?
Ans. 
Split horizon is a technique used in computer networking to prevent routing loops by not advertising routes back to the same interface they were learned from.
• Split horizon is used in distance-vector routing protocols like RIP to prevent routing loops.

• It works by not advertising routes back to the same interface they were learned from.

• Split horizon with poison reverse takes this a step further by advertising the route w...read more

Q4. What is routing protocol? What are the types of routing protocol?
Ans. 
Routing protocol is a set of rules used by routers to determine the best path for data packets to travel.
• Routing protocols help routers communicate with each other to dynamically update routing tables.

• Types of routing protocols include distance-vector (e.g. RIP), link-state (e.g. OSPF), and hybrid (e.g. EIGRP).

• Distance-vector protocols determine the best path based on hop count.

• Link-state protocols use a more complex a...read more

Q8. How does tracerout works?
Ans. 
Traceroute is a network diagnostic tool used to track the path packets take from one networked device to another.
• Traceroute sends packets with increasing TTL values to determine the path to a destination.

• Each router along the path sends back an ICMP Time Exceeded message, allowing traceroute to map the route.

• The final destination sends an ICMP Port Unreachable message, indicating the end of the route.

• Traceroute helps i...read more

Q9. If we see "*****" in tracerout, what it means?
Ans. 
The presence of '*****' in a traceroute indicates that the router is blocking the ICMP packets used by traceroute.
• The '*****' indicates that the router is not responding to the ICMP packets sent by the traceroute tool.

• This could be due to the router being configured to block ICMP traffic for security reasons.

• It can also be caused by a firewall or network filtering rules blocking the ICMP packets.
