Routing and Bandwidth Flashcards
What is dynamic routing?
Dynamic routing automatically adjusts the paths that data packets take based on current network conditions, using routing protocols like RIP, OSPF, EIGRP, and BGP.
What is Routing Information Protocol (RIP)
Uses distance vector routing, counting hops
What is Open Shortest Path First (OSPF)
Uses link state routing, calculates the shortest path.
What is Enhanced Interior Gateway Routing Protocol (EIGRP):
A hybrid routing protocol developed by Cisco, combines features of link state and distance vector.
What is Border Gateway Protocol (BGP)
Used for routing between different autonomous systems on the internet.
What is the difference between link state, distance vector, and hybrid routing protocols?
Link State
Each router has a complete map of the network (e.g., OSPF)
Distance Vector
Routers share information about the distance to destinations (e.g., RIP).
Hybrid
Combines features of both link state and distance vector (e.g., EIGRP).
What is static routing?
Static routing requires manual configuration of routes, which do not change unless manually updated by a network administrator.
What is a default route?
A default route is a route used by a router when there is no specific path to a destination in the routing table. It’s essentially a catch-all route for unknown destinations.
What is administrative distance in routing?
Administrative distance is a value used by routers to prioritize routes from different routing protocols, with lower values being preferred.
What is the difference between exterior and interior routing?
Exterior Routing: Manages routing between different autonomous systems, typically using BGP.
Interior Routing: Manages routing within a single autonomous system, using protocols like RIP, OSPF, and EIGRP.
What is Time to Live (TTL) in routing?
TTL is a field in the IP packet header that specifies the maximum number of hops a packet can take before being discarded. It prevents infinite loops in the network.
What is traffic shaping in bandwidth management?
Traffic shaping controls the amount and rate of traffic sent to the network to ensure efficient use of bandwidth and to meet network performance criteria.
