  2. Administrative distance - Wikipedia

    en.wikipedia.org/wiki/Administrative_distance

    For example, on Cisco routers, routes issued by the Open Shortest Path First routing protocol have a lower default administrative distance than routes issued by the Routing Information Protocol. This is because, by default on Cisco routers, OSPF has a default administrative distance of 110 and RIP has a default administrative distance of 120.

  3. Policy-based routing - Wikipedia

    en.wikipedia.org/wiki/Policy-based_routing

    In computer networking, policy-based routing (PBR) is a technique used to make routing decisions based on policies set by the network administrator.. When a router receives a packet it normally decides where to forward it based on the destination address in the packet, which is then used to look up an entry in a routing table.

  4. Link-state routing protocol - Wikipedia

    en.wikipedia.org/wiki/Link-state_routing_protocol

    Cisco literature refers to Enhanced Interior Gateway Routing Protocol (EIGRP) as a "hybrid" protocol, [12] despite the fact it distributes routing tables instead of topology maps. However, it does synchronize routing tables at start-up as OSPF does and sends specific updates only when topology changes occur.

  5. Distance-vector routing protocol - Wikipedia

    en.wikipedia.org/wiki/Distance-vector_routing...

    Distance is a measure of the cost to reach a certain node. The least cost route between any two nodes is the route with minimum distance. Updates are performed periodically in a distance-vector protocol where all or part of a router's routing table is sent to all its neighbours that are configured to use the same distance-vector routing protocol.

  6. Routing table - Wikipedia

    en.wikipedia.org/wiki/Routing_table

    Route table showing internet BGP routes . In computer networking, a routing table, or routing information base (RIB), is a data table stored in a router or a network host that lists the routes to particular network destinations, and in some cases, metrics (distances) associated with those routes.

  7. Routing protocol - Wikipedia

    en.wikipedia.org/wiki/Routing_protocol

    The specific characteristics of routing protocols include the manner in which they avoid routing loops, the manner in which they select preferred routes, using information about hop costs, the time they require to reach routing convergence, their scalability, and other factors such as relay multiplexing and cloud access framework parameters.

  8. Longest prefix match - Wikipedia

    en.wikipedia.org/wiki/Longest_prefix_match

    In this case, the longest prefix of the candidate routes is 192.168.20.16/28, since its subnet mask (/28) is longer than the other entry's mask (/16), making the route more specific. Forwarding tables often contain a default route , which has the shortest possible prefix match, to fall back on in case matches with all other entries fail.

  9. Packet Tracer - Wikipedia

    en.wikipedia.org/wiki/Packet_Tracer

    Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks.The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
