COMMAND: The command to run (add, delete, change, get, monitor, flush)-net: <dest> is a network address-host: <dest> is host name or address (default)-netmask: the mask of the route <dest>: IP address or host name of the destination <gateway>: IP address or host name of the next-hop router
Another limitation appears when routers do not respond to probes or when routers have a limit for ICMP responses. [17] In the presence of traffic load balancing , traceroute may indicate a path that does not actually exist; to minimize this problem there is a traceroute modification called Paris-traceroute, [ 18 ] which maintains the flow ...
In computer networking, dynamic routing (DR), also called adaptive routing (AR), [1] [2] is a process where a router can forward data via a different route for a given destination based on the current conditions of the communication circuits within a system. [3]
Examples of link-state routing protocols include Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS). [2] The link-state protocol is performed by every switching node in the network (i.e., nodes which are prepared to forward packets; in the Internet, these are called routers). [3]
A command prompt (or just prompt) is a sequence of (one or more) characters used in a command-line interface to indicate readiness to accept commands. It literally prompts the user to take action. A prompt usually ends with one of the characters $ , % , # , [ 18 ] [ 19 ] : , > or - [ 20 ] and often includes other information, such as the path ...
As each of these neighbors receives this information, they now recalculate the shortest path using it. For example: A receives a DV from C that tells A there is a path via C to D, with a distance (or cost) of 5. Since the current "shortest-path" to C is 23, then A knows it has a path to D that costs 23+5=28.
Equal-cost multi-path routing (ECMP) is a routing strategy where packet forwarding to a single destination can occur over multiple best paths with equal routing priority. Multi-path routing can be used in conjunction with most routing protocols because it is a per-hop local decision made independently at each router.
Using this map, each router independently determines the least-cost path from itself to every other node using a standard shortest paths algorithm such as Dijkstra's algorithm. The result is a tree graph rooted at the current node, such that the path through the tree from the root to any other node is the least-cost path to that node. This tree ...
