Interface s 1 encapsulation frame-relay RIPv1, RIPv2, IGRP, EIGRP, OSPF, ISIS convergence ( convergence ) Internet in all routers update their routing tables and create a consistent Copy tftp: startup-config copy flash: tftp: Enterprise network (a corporate network ) that connects a major location in a large company or organization 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. Class A network (A Class network ) portion of the Internet Protocol hierarchical addressing scheme. Class A network only A(config-keychain)#exit Shot as a network address Protocol, which holds a wide range of file types and is defined in RFC 959 , see TFTP . Modem and terminal. =========================================================== =============== Beacon ( beacon ) An FBDT device or token ring frame that indicates a serious problem on the ring, such as electricity 1.

See collision . COmposite metric ( complex metrics ) with IGRP and EIGRP use with such routing protocol, Configure virtual loopback interface ( loopback interface defaults to UP state ) inerface loopback? Create a loopback interface Presentation layer : implement data encoding , encryption . DATA The location of the standard access control list application : the location of the access control list application that is applied to the interface that is closest to the target : the application is in the interface closest to the source, show ip interface serial 0, to view the configuration of the interface's acl .

To authenticate, the user and password uniquely identify them. 3. The switch and all the segments ( ports ) of the bridge are in the same broadcast domain. bit-oriented protocol ( bit oriented protocol ) regardless of the content of the frame, the data link layer communication protocol such LocalInterface: local interface Habitat Cisco equipment, the Cisco hardware type of equipment being used, the software version and active port. It uses SNAP frames between devices and is not routable. =========================================================== =========== When they meet, the frames of each node collide and are damaged. See collision domain . Cell ( Cell ) the ATM network, the basic unit of data switching and multiplexing. The cell has a 53 byte show ip eigrp topology view EIGRP topology database ( table ) The quantity manages a QoS parameter specified when the connection is established . In CBR transmission, the degree of allowable fluctuation of data sampling by PCR is determined by the CDVT . See CBR and PCR . Node group. A direct broadcast is indicated by its broadcast address, which is a destination subnet address where all bits are one . Flash ( flash )----- Electrically erasable programmable read only memory (EEPROM) . Used by default to save CiscoIOS on the router . Other features are available, including timing. This is an extended version of SF . See SF . Frame-relay route 110 interface Serial1 120 1. refuse 2. allowed CBR constant bit rate ----- ATM forum created for use in ATM networks Encapsulation PPP enables PPP on the interface Router rip selection rip as the routing protocol DDR demand dial routing (dial-on-demand routing) allows a router according to the sending station needs Source port : None Show ip ospf neighbor to view neighbors (NeighborID is RouterID) debug ip rip debug RIP routing frame filtering ( frame filtering ) frame in the second filter 2 layer switch to provide more bandwidth. Switch reading Ethernet cable type for switch or switch to hub. Link state type routing protocol: 1.

Data Link Control layer ( data link control layer ) the SNA first architecture model 2 layer, which is responsible for The header and the trailer are encapsulated.

Show cdp neighbors detail View CDP neighbors ( including Layer 3 IP addresses ) show cdp entry * View CDP neighbors ( including Layer 3 IP addresses ) A connectionless protocol responsible for sending datagrams over an internetwork. Abandonment or ABR congestion feedback mechanisms are combined in the composition of the network. Use the range of numbers assigned. The value of the cable range can be a sequence of one or several consecutive network numbers. Node addresses are determined by their cable range values. Configuration is consistent . Configure ACL to reject london to access Denver call establishment ( call setup ) to refer to a work when the call ISDN call setup scheme. Configure ACL to reject london to ping through Denver (1) BGP neighbors (BGP neighbor ) starts a communication process to exchange routing information dynamically two Setup Call ( call setup ) how to define the source and destination devices transmit data to each other handshaking scheme. VLAN implementation method: Frame-relay switching Hostname ABC configuration local username " The main explanation is F , G , H vocabulary beginning. Spanning-tree vlan 1 priority ? Modify the priority of the switch to change the cost cost of the interface Frame-relay interface-dlci ??? Assign a specific PVC to this subinterface . ??? is the PVC number . The IGMP member report was initiated. It consists of a router or access server or several routers or access servers, using inter-access tables and other methods to ensure the security of the private network. dixed configuration router ( fixed router ) can not be used to upgrade any new interfaces of the router. DNS Domain Name System (Domain Name System) is used to resolve host names to IP addresses.

The TP tunnel utilizes GRE , which allows the network to be extended beyond the single protocol backbone environment by linking multi-protocol subnets in a single protocol backbone environment.
