routingtabell
A routingtabell, commonly known as a routing table, is a data structure inside a router or networked host that stores the routes used to determine where to forward packets. The table consists of entries that map destination prefixes to next-hop addresses or exit interfaces. Each entry typically includes the destination prefix (network address and prefix length), a next hop or interface, a metric, and a source indicating how the route was learned (static, dynamic protocol, connected, or local).
Routing tables are populated through static configuration or dynamic routing protocols such as OSPF, IS-IS, RIP,
Both IPv4 and IPv6 are supported, with entries expressed as appropriate prefixes. Dynamic protocols continuously exchange
In operation, the routing table guides the forwarding plane: for each incoming packet, the most specific matching
