routing protocols : Administrative Distance and multiple routes with the same mask

The video tutorial explains how OSPFv and RIP advertise the same network route, leading to a conflict resolved by administrative distance, which acts as a tiebreaker. It further discusses how routing decisions are made based on the longest match or best match criteria, with network 10.1.1.0/27 being chosen as the best route. Despite RIP having a higher administrative distance compared to OSPF, traffic is forwarded to router one due to the longest match rule.

What is the primary reason for using administrative distance in routing?

• To enhance network security

• To calculate the shortest path

• To break ties when multiple protocols advertise the same route

• To determine the fastest route

Which two protocols are mentioned as advertising the same route in the video?

• IS-IS and BGP

• OSPF and RIP

• EIGRP and OSPF

• BGP and EIGRP

What is the role of administrative distance in routing decisions?

• It is used to calculate the shortest path

• It is used to break ties between different routing protocols

• It is used to determine the fastest route

• It is used to enhance network security

How is the best route determined when multiple routes are available?

• By picking the route with the highest bandwidth

• By choosing the route with the lowest administrative distance

• By opting for the route with the shortest delay

• By selecting the route with the longest match

What happens to traffic when RIP has a higher administrative distance compared to OSPF?

• Traffic is forwarded to the route with the shortest path

• Traffic is forwarded to the route with the highest bandwidth

• Traffic is forwarded to the route with the longest match

• Traffic is forwarded to the route with the lowest delay
