SRWE Module 14 Flashcards

Front

The most optimal route chosen by a router to forward packets based on routing metrics (e.g., lowest cost, shortest hop count, etc.).

Back

Best Path

Front

A routing rule that selects the route with the most specific prefix match to the destination IP address in the routing table.

Back

Longest Match

Front

The number of bits used in an IP address to represent the network portion of the address, typically written as a subnet mask (e.g., /24).

Back

Prefix Length

Front

The router that is the next destination point on the path to a given destination IP address.

Back

Next-Hop Router

Front

A packet-forwarding method where the router performs packet forwarding via the CPU, typically used in older routers or under low traffic conditions.

Back

Process Switching

Front

A packet-forwarding technique where the router uses a fast lookup cache to forward packets more efficiently than process switching.

Back

Fast Switching

Front

A high-performance, hardware-based forwarding mechanism in Cisco routers that uses a Forwarding Information Base (FIB) and an adjacency table for fast packet forwarding.

Back

Cisco Express Forwarding (CEF)

Front

The origin of routing information, which can include static routes, connected routes, or routes learned from dynamic routing protocols.

Back

Route Sources

Front

Manually configured routes on a router that do not change unless manually updated by the network administrator.

Back

Static Routes

Front

Protocols (e.g., OSPF, EIGRP, BGP) that automatically adjust routing tables based on network topology changes, allowing routers to communicate and learn optimal routes.

Back

Dynamic Routing Protocols
