  • BGP

    BGP (Border Gateway Protocol) is the path-vector routing protocol that exchanges reachability between autonomous systems and holds the Internet together.

  • Default gateway

    A default gateway is the router address a host sends packets to whenever the destination lies outside its own subnet and no more specific route exists.

  • Dynamic routing

    Dynamic routing is a routing method in which routers exchange information through routing protocols and update their routing tables automatically.

  • OSPF

    OSPF (Open Shortest Path First) is a link-state interior routing protocol that computes shortest paths inside a network using areas and link costs.

  • Router

    A router is a network device that forwards IP packets between separate networks, choosing each next hop from its routing table by longest prefix match.

  • Routing table

    A routing table is the list of destination prefixes and next hops that a router or host consults to decide where to forward each IP packet.

  • Static route

    A static route is a routing table entry that an administrator configures manually, telling a router which next hop or interface reaches a given network.
