The main purpose of a routing table is to help routers make effective routing decisions. Whenever a packet is sent through a router to be forwarded to a host on another network, the router consults the routing table to find the IP address of the destination device and the best path to re...
A routing table is a type of data file that acts as a map and is often installed on a router, networked computer or other hardware. The routing table contains information about various routes between devices in order to present the most efficient paths for data packets. Advertisements Techoped...
What does the SRP distribute to the line modules when arouting table changes?() A. updated RIB-Out B. link-state information C. an incremental update D. the complete routing table 相关知识点: 试题来源: 解析 D.the complete routing table ...
a netmask, short for network mask, is a 32-bit value used in computer networking to divide an internet protocol (ip) address into a network address and a host address. it is often represented as a series of four numbers separated by dots, known as dotted-decimal notation. the netmask ...
In its simplest form, a wide-area network (WAN) is a collection of local-area networks (LANs) or other networks that communicate with one another.
Broadcast and collision domainsare important concepts in Ethernet switching. The former is a logical network segment where devices can directly communicate without the need for routing. When a device sends a broadcast message, all other devices in the domain will receive it. By contrast, a collisio...
Network routers use certain protocols to discover the most efficient network paths to other routers. These protocols are not used for transferring user data. Important network routing protocols include: BGP: The Border Gateway Protocol (BGP) is an application layer protocol networks use to broadcast ...
Let's verify the routing table and forwarding table of R1. Now the backup path via R3 is installed as the best path and the route through R4 as a backup path. R1#sh ip route 5.5.5.0 Routing entry for 5.5.5.0/24 Known via "ospf 1", distance 110, metric 15, type inter area ...
BGP is aroutingprotocol used to exchange network layer reachability information (NLRI) between routing domains. Such domains are often called ASs because different administrative organizations control their own routing domains. Currently, the Internet is a large-scale network consisting of multiple intercon...
Layer 3 IP address routing table, and transport-layer port numbers. OpenFlow switches forward data based on flow tables that contain network configuration information of all layers on the network, instead of 5-tuple information. The entries in a flow table are flexible combinations of certain keyw...
