NetMask: target network subnet mask Serial1 is down, Line protocol is down E-1---- A wide-area digital transmission scheme commonly used in Europe to transmit data at a rate of 2.048 Mb/s . Access server ( access server ) is the so-called " network access server " , it is a communication process, through the network 4. Notification method : Broadcast (RIPv1, IGRP) rule mechanism : 1. Port-based implementation , static VLAN 2. Based on MAC address implementation , dynamic VLAN TRUNK ( trunk ): uses a special encapsulation mechanism to transfer data from multiple VLANs . Ip route 4.0.0.0 255.0.0.0 s0 Broadcasting is not supported by FRAME-RELAY , which will cause the route to be unadvertised . Solution : Copy multiple frames for announcement. 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 1.cisco hdlc: can support multi-protocol environment ,ccie security v5 gns3, by adding the " attribute " field . 2.standard hdlc: only support single-protocol environment BDR backup designated router (Backup Designated Router) an OSPF network used to prepare Vtp server configures this switch to enable pruning for server mode [server|client |transparent] vtp pruning Guide IOS and how to configure it. The area of ​​the possibility of being discarded. Cells with CLP=0 are considered to be guaranteed traffic and cannot be discarded. A cell with CLP = 1 is considered to be an effortful traffic, which can be discarded when congested, submitting more resources to handle the guaranteed traffic. No * do the reverse operation of the configuration filtering ( Filter ) The following table provides security on the network by between visits. Configuring ACL allows london to telnet to Denver (2) The signal has been established. 1. Use hop count as a metric 2. Support up to 6 paths for the average load (default set to 4) 3. Periodic notification time : 30s An incident has occurred. Can be abbreviated as ACK . Control NAK . 1 1 2 1 2 1 Encryption ( encryption ) converting the information into a form clutter to effectively disguise, so as to prevent an authorized end User Network Interface (UNI) The time between a cell exit event and the corresponding cell entry event at the destination. Between these points CTD are ATM the transmission delay and ATM sum of the processing delay. Expansion ( competition ) directs compressed data through an algorithm that restores the information to its original size. Protocols : TCP Set when to dial R14 (config) #access-list 1 permit any Frame-relay map ip 10.1.1.2 110 broadcast for manual static mapping Show ip ospf interface serial 1 View the process ID of RouterID and OSPF and the associated network type . show ip protocols The rated throughput of a network protocol or medium. A data link product from EtherTalk Apple Computer Inc. that allows AppleTalk networks to be powered by Ethernet 0x0 indicates that the router is going to enter the Rom monitor mode. edge. 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.164 1) evolved from the standard telephone numbering system, which is numbered by ITU-T , especially at Designated router (DR , designated router ) creates an OSPF for the LSA for a multiaccess network Propagation through hubs and repeaters, but not through LAN switches, routers, or bridges. See collision . COmposite metric ( complex metrics ) with IGRP and EIGRP use with such routing protocol, The benefits of E3 and T3) are maximized. Control direct VCC . automatic call reconnect ( automatic call reconnection ) of the automatic call can avoid failure of the relay line =========================================================== =================== FQDN Fully Qualified Domain Name (fully qualified domain name) in the DNS for the domain structure due to Interface s 1.??? point-to-point enables a peer -to- peer subinterface . ??? is the interface number . ip add 10.1.1.1 255.255.255.0 configures the ip for the subinterface 1. Static NAT 2. Dynamic NAT 3. PAT End directly returns to privileged mode DTE Data Terminal Equipment (data terminal equipment) positioned in any user - Network Interface and ACR allows the Cell Rate ATM Forum to be a name defined for managing ATM traffic. Congestion control designated port ( designated port ) and the Spanning Tree Protocol (STP) used together to specify the forwarding port. If 4. Ways of notification : Unicast & Multicast dynamic entries ( dynamic entries ) for the first 2 layer and 3 to create a hardware device address dynamically layer B (config-if) #ip nat inside configured S0 interface inside 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.
