Version 2 configures the rip version to version 2 no auto-summary to turn off automatic summarization congestion avoidance ( congestion avoidance ) to minimize latency, the ATM network for controlling the system into Node group. A direct broadcast is indicated by its broadcast address, which is a destination subnet address where all bits are one . =========================================================== =============== The line is damaged , the interface does not have any connection cable. Serial1 is up, line protocol is down Packaging method. HDLC is a bit-oriented synchronous data link layer protocol created by ISO , which originated from SDLC . However, most HDLC vendor implementations ( including Cisco 's ) is patented. See SDLC . The over rate is the maximum rate minus the insurance rate. Depending on the availability of network resources, excess traffic can be dropped during congestion. Contrast maximumraten Virtual circuits in the network. Directed broadcast (a direct broadcast ) a data frame or packet is transmitted to a remote network segment specific Bits are used to define the network. Only 8 bits are used to define hosts on the network. Broadcasting is not supported by FRAME-RELAY , which will cause the route to be unadvertised . Solution : Copy multiple frames for announcement. Used to " fused " the capabilities of various routers and switch sets . Router eigrp 100 coimnection ID ( connection ID) each into the router's Telnet identifying the session analysis. Show sessions CDP Cisco Discovery Protocol (Cisco Discovery Protocol) Cisco proprietary protocol, used to tell the neighbor address resolution ( ARP ) to resolve the differences between computer addressing scheme of the process. Address resolution routing Classless ( stepless routing ) transmits routing update routing subnet mask. Stepless road cut-through frame switching ( straight-frame exchange ) A frame of data flowing through the switch switching technology Other features are available, including timing. This is an extended version of SF . See SF . =========================================================== =============== 4. Ways of notification : Unicast & Multicast access method ( access method ) network devices gain network access Wan style. A connectionless protocol responsible for sending datagrams over an internetwork. Area ( Area -----) rather than physical segment of a set of logical ( based CLNS , DECnet , or OSPF) and their attached devices. Areas typically use routers to connect to other areas to create an autonomous system. See autonomous system . 4. Ways of notification : Unicast & Multicast CBR constant bit rate ----- ATM forum created for use in ATM networks Interface Serial1 no ip address Corelayer The top layer of the Cisco three-tier hierarchical model that helps design, build, and maintain a =========================================================== =============== ATCP AppleTalk control program (the AppleTalk Control Program) : establishing and configuring AppleTalk over B(config)#inte s 0 The pick-up point is specified in the destination field of the packet. See SSAP and SAP . Target port : 23 Listen for digital signals on the cable before. In addition, the CSM elbow CD allows all devices on the network to share the same cable, but one at a time. If both devices are sending at the same time. A frame collision will occur and an interference pattern will be sent, the device will stop transmitting, wait for a predetermined amount of time, and then try to send again. The reservoir, which can be electrically erased and reprogrammed, is physically located on the EEPROM chip. Flash memory allows software images to be stored, booted, and rewritten as necessary. By default, Cisco routers and switches use flash to save IOS . See EPROM and EEPROM . Router, which is required for other special tasks in OSPF operations. A multi-access OSPF network with at least two routers selects a router through the OSPF Hello protocol, which makes the multi-access network necessary neighbors. Reliable transmission mainly involves physical addressing, line procedures, network topology, error notification, orderly delivery of frames, and flow control. The IEEE has further split this layer into a MAC sublayer and an LLC sublayer. Also known as the link layer. Can be compared to the data link control layer of the SNA model. See Application layer , LLC , MAC , Network layer , Physical Banner motd [char c] also ends with [char c] another line Using PPP encapsulation and support on the wire, it is a security feature that identifies the remote end and helps prevent unauthorized users. After the CHAP is executed, the router or the pick-up server determines whether a given user is allowed to access. It is a new, more secure protocol than PAP . Compare PAP . NextHopIP: Next hop IP ESF extended superframe (Extended Superframe) of 24 composed of frames, each frame of 192 bits , the first 193 than It enables two socket (Socket) can be reliably performed between transactions, wherein a request for another execution of a given task and to report the results. ATP grabs both the request and the response, ensuring that the request - response is exchanged without loss. In attenuation ( attenuation ) communication,ccie security lab iou, the weakening or loss of signal energy, usually caused by distance. Routers in the same autonomous system are able to learn to advertise related routes to each other . ASP AppleTalk Session Protocol (APC) is established and maintained using ATP . 10.1.1.1/0.0.0.0 ATM ATM (Asynchronous Transfer Mode) by a fixed-length 53 -byte element identifier ++<6> + x DVMRP distance between the amount of multicast routing protocol (Distance Vector Multicast Routing Protocol) is mainly based on Routing Information Protocol (the RTP) , the Internet gateway protocol a common, strong The switch, Cisco calls it a switch-fabric . The switches in the switch fabric must keep track of the frames received on that switch port and must track the frames they belong to as they pass through the switch fabric. IOS Cisco Cisco Internetwork Operating System Software (Cisco Internetwork Operating System software) ----- as CiscoFusion provide the functionality shared by all products in the off-line configuration, scalability and security of Cisco core routers and switches series. See CiscoFusion . OSPF and RIP . Target : 172.16.3.1 BGP speaker (BGP speakers ) advertises its routing prefix or router. The defined length includes a 5- byte header and a 48- byte payload that identify the stream of the cell . See =========================================================== =============== HDLC: No port is activated with the no shutdown command The program accepts the data and brings it into the 48- byte payload segment of the ATM layer . CS and SAR are the two sublayers of AAL . Currently, the four AALs recommended by ITU-T are AAL1 , AAL2 , AAL3/4 and AAL5 . AALs are distinguished by the source - destination timing they use , whether they are CBR or VBR, and whether they are for connection-oriented or connectionless mode data transmission.
