Routing Fundamentals Flashcards
is the basic element of data communication networks, which is the process of selecting paths on a network along which packets are sent from a source to a destination.
routing
enables a router to compare the destination address to the available routes in its routing table and to select the best path.
path determination
are the path information used to guide packet forwarding
routes
is a network device that forward packets to a destination subnet based on routes. It maintains an IP routing table that stores routing information.
routing device (Router)
is the overall network-wide process of finding the most efficient path for forwarding the IP packet from source to destination through the use of network routing tables, protocols, and algorithms.
Packet routing
A route contains the following information:
- Destination
- Mask
- Outbound interface
- Next hop
Identifies a destination subnet
Destination
identifies a subnet together with a destination IP address
Mask
indicates the interface through which a data packet is sent out of the local router
Outbound interface
indicates the next-hop address used by the router to forward the data packet to the destination subnet
Next hop
