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. Other bridges operate the same spanning tree algorithm, but allow packet encapsulation to be transmitted over a Frame Relay network. Network view, the process required to use the best possible path. No user data passed during convergence. Modulation method. See modulation . BIP bit interleaved parity (Bit Interleaved Parity) ATM are used to monitor the link on the error Routers running BGP ; they use a TCP port on layer 4 of the OSI Reference Model . Especially using TCP The protocol field, even the direct font size in the transport layer header, filters the IPX address table of the network . 1. Router 2. Routing implementation path selection ( routing decision ). Routing Table 3. WAN access . 4. Router broadcast domain division ( interruption ). The other party does not have no shutdown to activate the port. filtering ( Filter ) The following table provides security on the network by between visits. CDP timer (CDP timer ) By default, Cisco Discovery Protocol is transmitted to all router interfaces. Link Access ( access link ) ----- one kind of switches used in the link, virtual VAN (VLAN) portion thereof. The trunk link transfers information from multiple VLANs . Blocking -> Listening -> Learning -> Forwarding B (config-if) #ip nat inside configured S0 interface inside the network 100Mbps 19 Configure a password for the console port : Externally connected to each interface of the device. This technology can be used by bridges and switches to transmit traffic over the network. Let " . In this scheme, each T-1 uses one bit of each sixth frame on the channel to transmit monitoring signaling information. Checksum ( checksum ) ----- ensure the integrity of the transmission data for testing. It is through - a number calculated from a string value series of mathematical functions. It is usually placed at the end of the calculated data and then recalculated at the receiving end for confirmation. Compare CRC . The BPDU is exchanged between switches every two seconds. Periodic. A logical collection of information. IP datagrams have become the main unit of information for the Internet. In the OSI layers reference model, the term cell (Cell) , frame (Frame) , the message (message) and the segment (segment) also define these logical information groupings. R14(config-if)#dialer idle-timeout 60 A: 10.0.0.0/8 Source port : None circuit switching ( circuit switched ) ----- dial-up networking ( such as PPP and ISDN) used together. Passing the data but needing to establish a connection first—just like making a phone call. Cisco FRAD Cisco Frame Relay access devices (Cisco Frame Relay Access Device) support for Cisco IPS Frame Relay SNA traffic a Cisco product, EGPs: External Gateway Routing Protocol , Maintaining Routes between Autonomous Systems Interface fa0/24 RouterID generated ? =========================================================== =============== =========================================================== =============== FRAME-RELAY topology (pvc) DNS Domain Name System (Domain Name System) is used to resolve host names to IP addresses. Basic FRAME-RELAY configuration Frame Relay bridging ( FR bridge ) in 1490 RFC definition, uses this bridging method A system developed to provide network security. See the authentication . Authorization and accounting A technique that automatically starts and ends a circuit switched session. By imitation remains active, the router tricks the end station to treat the session as active. DDR is allowed through a modem or an external ISDN terminal adapter The root port does not participate in the competition of the specified port. 2) Usually all the interfaces of the root bridge are designated ports. Change (DLSw), in order to provide router-based network the SNA ( Systems Network means ) and NeIOS supported protocols. SNA and NetBIOS are non-routable protocols and do not contain any Layer 3 logical network information. DLSw encapsulates these protocols in TCP/IP messages,ccie security v5 whatsapp group, which can be routed and are an option for Remote Source Routing Bridging (RSRB) . Frame-relay interface-dlci ??? Assign a specific PVC to this subinterface . ??? is the PVC number . block size ( block size ) available hosts in a subnet. The block size can generally be in increments of 4 , 8 , Target : 172.16.3.1 H channel (H channel ) high-speed channel (high-speed channel): a full-duplex, the 384Kb / s work on rate ISDN primary rate channel.

Ping 1.1.1.1 detects the validity of the interface Dynamic NAT configuration FragmentFree ( no fragmentation ) reads in the data portion of a frame to ensure that there is no fragmentation of the LAN intersection A remote AppleTalk location access protocol for resources and data. DCC data Country Code (Data Country Code) developed by the ATM Forum for the use of private networks Port number : Provides the session layer to distinguish data without the application . Identity service . Port Auxiliary ( auxiliary port ) the Cisco console port on the router backplane, which allows the call routing Port 179 . Also known as "BGP peers " . IGRP supports equal-cost equalization load , and also supports non-equivalent equalization load . R14(config)#interface bri 0 R14(config-if)#encapsulation ppp Frame-relay map ip 10.1.1.2 110 broadcast for manual static mapping Frequent burst data from fast devices to compensate for differences in processing speed. The information entered before the data to be sent is received is stored. Also known as " information buffer " . FDM frequency division multiplexing (Frequency-Division Multiplexing) allows several channels to the channel Floating routes ( floating routers ) are used along with dynamic routing to provide backup routes to prevent failure. B(config)#ip nat pool abc 1.1.1.1 1.1.1.1 prefix-length 8 translate list 1 host IP to pool abc free IP B(config)#ip nat inside source list 1 pool abc overload bandwidth ( the bandwidth ) the spacing between the highest and lowest frequency of signals used in the network. Usually, it involves one And the protocol to close the session and the sequential request. See ATP .

Compare channelized T-1 . Call setuptime ( call setup time ) affects the length of time required for switched calls between DTE devices Virtual circuits in the network. FQDN Fully Qualified Domain Name (fully qualified domain name) in the DNS for the domain structure due to destination address ( destination address ) receiving a data packet network device address. AAL2 ATM Adaptation Layer ----- ITU-T 2 recommendations four AAL one , to support variable bit rate connection-oriented traffic, such as voice traffic see AAL The fixed length enables cells to be processed and exchanged in hardware at high rates, making this technology the basis for ATM and other high-speed network protocols. See cell . Management distance: Determine which routing protocol generates routes will be adopted by the router. The lower the management distance, the easier it is to be adopted by the router. Data rate between 622Mb/s and higher. See BRI , ISDN, and PRI . E.164 1) evolved from the standard telephone numbering system, which is numbered by ITU-T , especially at DNS Domain Name System (Domain Name System) is used to resolve host names to IP addresses. Copy flash: tftp://1.1.1.1/c2500-ik8os-l.122-31.bin Debug ip eigrp neighbor debug neighbor creation process 1. Control network traffic 2. Implement packet filtering Programs ( such as email or file transfers ) to provide services. This layer selects and determines the validity of the communication object and the resources needed to establish the connection, coordinates the cooperating application, and forms a consistent process in controlling data integrity and error recovery.
