Redundant Path A redundant path is a secondary network path configured or available to preserve service when the primary path fails, degrades, or becomes congested. It is used to improve availability and… Concept/Framework Region Region is a geographic area used to describe a bounded location for planning or organization. It may be physical, operational, or administrative depending on context. Concept/Framework RIP RIP is a distance-vector routing protocol that shares routing information with neighboring routers. It uses hop count as its main metric and is common in legacy networks. Protocol RIP-NG RIP-NG is the IPv6 version of RIP, using distance-vector routing behavior to exchange routes in IPv6 networks. It is suited to smaller or legacy deployments. Protocol Route Advertisement Route advertisement is the process by which a routing device or system announces routes or prefixes to one or more peers. It is how reachability information spreads across a routing… Protocol Route Leakage Route leakage is the accidental or unauthorized export of routing information outside the domain where it was meant to stay. It occurs when filtering, policy, or boundary control fails. Concept/Framework Route Poisoning Route Poisoning is a routing technique that advertises a failed route with an invalid metric so routers treat it as unreachable. It helps prevent loops and speed convergence. Protocol Route Redistribution Route Redistribution is the process of transferring routes between routing domains or protocols so reachability information can be shared. It is controlled by policy and filtering rules. Protocol Route Reflection Route Reflection is a BGP technique that allows one router to advertise routes to other routers within the same routing domain, reducing the need for full-mesh peering among internal BGP… Protocol Route Summarization Route Summarization is the aggregation of multiple specific routes into a broader prefix that represents the same destination space at a higher level, reducing routing table size and protocol overhead.
