Holddown Timer Holddown Timer is a routing control mechanism that temporarily suppresses acceptance of route changes after a failure to reduce routing instability by holding a route in a suppressed state for… Operations Holdover Timing Holdover Timing is the ability of a system to continue providing acceptable timing when its external reference is temporarily unavailable. It maintains timing during reference loss. Operations Hub And Spoke Architecture Hub And Spoke Architecture is a network design in which endpoints connect through a central hub rather than directly to one another. It simplifies interconnection but centralizes dependency. Concept/Framework IBGP IBGP is the internal BGP session used to exchange routes within the same autonomous system. It distributes internal routing information across a domain. Protocol IETF The open standards organization responsible for developing core internet protocols, including DNS and BGP, publishing its work as RFCs through an open, engineering-driven consensus process open to any interested participant. Regulatory & Compliance Inbound Reachability Inbound reachability is the property of a network or service being accessible from external sources through the appropriate routing and policy paths. It is a prerequisite for externally facing services… Concept/Framework Inter-Domain Routing Inter-domain routing is the process of advertising and selecting network reachability information between separate autonomous systems or similar routing domains. It uses policy to decide which routes are accepted, exported,… Concept/Framework Interior Gateway Protocol An Interior Gateway Protocol is a routing protocol used to exchange reachability information within a single network domain. It helps routers choose internal paths and converge on a shared view… Protocol Internet Exchange A shared physical facility where multiple networks interconnect to exchange traffic directly with each other, providing common switching infrastructure that lets many participants establish connectivity in one location rather than… Concept/Framework Internet Routing Internet routing is the distributed routing process that advertises, exchanges, and selects reachability information across the internet. It is the mechanism that allows traffic to cross administrative boundaries and reach… Concept/Framework
