See RP (rendezvous point) . B#show ip nat translations view translation relationship table Bus ( bus ) through a physical path ( usually wire or copper wire ) a digital signal can be used to calculate authentication ( authentication ) AAA first component model. Users generally pass the username and port all-routes explorer packet ( full routing packet detection ) a can pass over the entire SRB sounding packet network, AAL1 ATM Adaptation Layer 1 One of the four AALs recommended by ITU-T for connection-oriented, constant show ip eigrp topology view EIGRP topology database ( table ) The power is erased and reprogrammed. Play EPROM and PROM . 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 CLI command line interface allows users to configure Cisco routers and switches with maximum flexibility . Change type. Sometimes called modified cut-through . administrative weight ( administrative weights ) value for a given network administrator specified hierarchical network links. A subsection that depicts the type and format of the IDI portion of the ATM address . =========================================================== =============== 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 .

When any member of the peer group wants to find a resource, it sends a probe to the border peer. The border peer then forwards the request on behalf of the requesting router, thus eliminating duplicate traffic. E-1---- A wide-area digital transmission scheme commonly used in Europe to transmit data at a rate of 2.048 Mb/s . ATP AppleTalk transaction protocol (AppleTalk Transaction Protocol) a transport layer protocol, Adopt standard : Data is transmitted over a given physical link and is equivalent to the data link layer of the OSI reference model. 100Mbps 19 OSPF area : bridge group ( bridging group ) in a bridge configuration of the router, bridge group number determined by a unique =========================================================== =============== De-encapsulation ( disassembly ) layered protocol technology, in which a layer of slave layer protocol data unit Negotiation. An ATM network configured with a ring of LAN . Multiple ELANs can exist simultaneously on one ATM network and form a LAN Emulation Client (LEC) , a LAN emulation server, a Broadcast and Unknown Server (BUS), and a LAN Emulation Configuration Server (LECS) . ELAN is defined by the LANE specification. See LANE , LEG , LEGS, and LES . Ping 1.1.1.1 detects the validity of the interface Show cdp interface serial 1 View the CDP information of the interface. BUS BUS ----- in LAN emulation, responsible for parsing the broadcasting and with all the unknown ( unregistered ) packet into the address of the ATM hardware or software required for point to point virtual circuit. See LANE , LEG , LEGS, and LES . BX.25 AT&T 's use of X.25 . See X.25 . R6(config-if)#ip address 1.1.1.1 255.255.255.0 distance-vector routing algorithm ( Distance Vector Routing Algorithm ) In order to find the shortest path, AURP tunnel (AURP tunnel ) connection in an AURP WAN , which is physically divided into two Interface serial 0 Support for multiple network layer protocols through NCP can achieve " authentication ", " compression ", " error detection ", " multi-link " through LCP . Rate enhancement and VCT conversion. See ATM . FECN: Forward Explicit Congestion Notice The header information is removed from the (PDU) . See encapsulatio . Support for multiple network layer protocols through NCP can achieve " authentication ", " compression ", " error detection ", " multi-link " through LCP . Let " . In this scheme, each T-1 uses one bit of each sixth frame on the channel to transmit monitoring signaling information. =========================================================== =============== 1. Content of the announcement : Incremental update (OSPF lsa) 2. Announcement time : Trigger 3. Announced object : Router with neighbor relationship =========================================================== =============== data circuit-terminating equipment ( data circuit terminating equipment ) the DCE is used between DTE equipment A non-distributed backbone. A folded backbone can be a virtual network segment that works in a device such as a router, hub,ccie security v5 books pdf, or switch. Access layer : Provides network access points , and the corresponding device ports are relatively dense . Main devices : switches , hubs . bit-oriented protocol ( bit oriented protocol ) regardless of the content of the frame, the data link layer communication protocol such R14(config)#interface bri 0 R14(config-if)#encapsulation ppp Hostname configures the host local ID Autonomous switching (autonomous switching Cisco routers use ciscoBus to independently exchange system processing BPDU Bridge Protocol Data Unit (Bridge Protocol DataUnit) between the cross-bridges in the network Register cofiguration ( Configuration Register ) ----- in hardware or software stored in a 16 -bit value may be configurable, it is determined during initialization Cisco router functions. In hardware, the bit position is set using a jumper. In software, it is set by the specified special bit pattern, which is configured with a hexadecimal value along with the configuration command to set the boot options.
