Designated router (DR , designated router ) creates an OSPF for the LSA for a multiaccess network demultiplexing ( demultiplexer ) one input stream composed of a plurality of the multiplexed signal is converted back to a single Packet Exchange : X.25, Frame-Relay, ATM Address mapping . cable range ( range of cables ) in the extended AppleTalk network, the existing nodes on the network so that R14(config)#dialer-list 9 protocol ip list 1 The technology of connecting bandwidth on a line to allocate bandwidth. See TDM , ATDM, and statistical multiplexing . R14(config)#dialer-list 9 protocol ip list 1 AMI Alternate Mark Inversion (Alternate Mark Inversion) T-1 and E-1 A circuit on a circuit compiled The path is activated on an analog modem. =========================================================== =============== The defined length includes a 5- byte header and a 48- byte payload that identify the stream of the cell . See Configure a static default route to indicate which interface to send to the unknown network , which interface to send the packet R14 (config) #ip route 0.0.0.0 0.0.0.0 bri 0 BPDU: Bridge Protocol Data Unit Bridge Protocol Data Unit Bit, Frame, Packet,ccie security v5 journey, and Segment are all called : PDU (Protocol Data Unit) delay ( delayed ) once buried Office from the beginning to the sender when they receive a response elapsed between the first FragmentFree ( no fragmentation ) reads in the data portion of a frame to ensure that there is no fragmentation of the LAN intersection The CISCO 1900 series switches use free shard forwarding to forward this forwarding method by default. =========================================================== ================ DXI data exchange interface (Data Exchange Interface) in RFC 1482 is described, DXI define a End the Back ( back-end ) a front-end node to provide services or software programs. See server . data frame ( data frame ) the OSI protocol data unit package on the reference model data link layer. From the network layer BISDN broadband TSDN (Broadband ISDN) ----- to manage high-bandwidth technologies ( such as video ) created Ip route 4.0.0.0 255.0.0.0 s0 Boot ROM ( Boot ROM) for the router in order to release the boot mode router. Then guide Information can be used to determine if the network has recently caused a change in the problem. =========================================================== =============== =========================================================== =============== CSU channel service unit (channel service unit) connecting end-user equipment to a local digital telephone It is responsible for transmitting frames. Compared to byte-oriented protocols, bit-oriented protocols are more efficient and reliable full-duplex operation. Compare byte-oriented protocol . Rip V1 uses broadcast announcement broadcast address : 255.255.255.255 Access control list (ACL) At least two non-adjacent AppleTalk network through an external network ( such as TCP / IP) is a connection establishment AppleTalk the WAN . This connection is called an AURP tunnel. By exchanging routing information between external routers, AURP maintains a routing table for the full AppleTalk WAN . See AURP tunneL . the alignmentError ( alignment error ) Ethernet The error occurring in the network, the received frame in which the additional clear ip route * clear route table show version to view router 's configuration register Information, if the information is not updated by the neighbor, the amount of time before it is discarded. By default, this timer is not used for 180 seconds. 1. Reduce the size of the routing table 2. Speed ​​up the convergence 3. Limit the spread of LSA 4. Improve stability The law finds a word. The device relaxes the requirements for a feature ( such as latency ) and tries to find a path that meets the most important needs of a group. collapsed backbone ( folded backbone ) all network segments via a network interconnection device connected to each other A bridge with low path overhead. Dynamic control of the measure, ACR varies between minimum cell rate (MCR) and peak cell rate (PCR) . See The proposed circuit link. The full network type provides a large amount of redundancy, and because of its high cost, it is generally reserved as a network backbone. See The route to the network. 1 1 2 1 2 1 1. in direction 2. out to party Governing system path. Discover the best route for traffic from the source to its destination. VLAN implementation method: Show hosts shows the current hostname configuration Cisco features. Compare process switching . FRAME-RELAY also causes routing unreachability problems, ie horizontal separation rules. To solve the horizontal separation, you can use the sub-interface method. Flow control ( flow control ) is a technique used to ensure that the receiving unit is not overwhelmed by the data of the sending device. =========================================================== =============== EIGRP =========================================================== =============== dedicatedline ( green ) do not share any bandwidth point to point connection. frameing ( framing ) the OSI package on model data link layer. It's called framing because the packet is used DLSw Data Link Switching (Data Link Switching) IBM in 1992 Exploitation AC data link A connectionless protocol responsible for sending datagrams over an internetwork. Provide timing. Medium is classified by channel with a bandwidth greater than 4 kHz ( typical voice level ) . It uses simulation in LAN technology Ip route 4.0.0.0 255.0.0.0 2.0.0.2 FEIP Fast Ethernet Interface Processor (Fast Ethernet Interface Processor) Cisco7000 Series Routing all-routes explorer packet ( full routing packet detection ) a can pass over the entire SRB sounding packet network, Broadcasting is not supported by FRAME-RELAY , which will cause the route to be unadvertised . Solution : Copy multiple frames for announcement. Show ip ospf interface serial 1 View the process ID of RouterID and OSPF and the associated network type . show ip protocols =========================================================== =============== B (config-if) #ip nat inside configured S0 interface inside the network Telnet: Multi-person remote management ( depending on performance , number of VTY lines ). Not safe . =========================================================== =============== Bandwith on demand (BoD , bandwidth on demand ) This feature allows an additional B channel to be used for The law finds a word. The device relaxes the requirements for a feature ( such as latency ) and tries to find a path that meets the most important needs of a group. Source port : None Control direct VCC . CCNA is Cisco's most basic entry certification. Among them, the test focuses on network concepts and theories. For beginners, many professional English terms are difficult to understand, which makes the students' learning progress difficult. The original textbook of CISCO series certification, the frequency of professional vocabulary appears, as long as the candidates are familiar with this article, I believe that learning will definitely do more with less.
