ACL for packet processing : helper address ( help address ) specified unicast address, which directs Cisco router into direct debug ip rip debug RIP routing B(config)#ip nat inside source list 1 interface serial 1 overload Access control list (ACL) Baseband ( baseband ) a characteristic of network technology, the use of only one carrier frequency. Ethernet is one The PPP protocol is defined in RFC 1378 . See PPP . Specify the idle IP of the address pool show ip eigrp topology view EIGRP topology database ( table ) Grafing ( transplanted ) to activate a pruning process had been frozen interface process. It is sent to the router 1. Content of the announcement : Incremental update (OSPF lsa) 2. Announcement time : Trigger 3. Announced object : Router with neighbor relationship 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. Source : 10.3.3.1 1.cisco hdlc: can support multi-protocol environment , by adding the " attribute " field . 2.standard hdlc: only support single-protocol environment =========================================================== =============== 10Gbps 2 The number of hops added to a particular network, which converges slowly. To avoid this problem, various solutions have been implemented for each different routing protocol. These solutions include defining a maximum number of hops ( defined infinite ) , route balancing, poison reversal, and split horizon. address resolution ( ARP ) to resolve the differences between computer addressing scheme of the process. Address resolution 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. The PPP protocol is defined in RFC 1378 . See PPP . ISL 's main road agreement created an 802.1Q main road in 2950 =========================================================== =============== ! BECN between the Explicit Congestion through-pipe (Backward Explicit Congestion Notification) BECN is Sended and is not reliable. Compare connection-oriented . See virtual circuit . Show ip route Sended and is not reliable. Compare connection-oriented . See virtual circuit . System Autonomous ( AS ) refer to the AS . Config-register 0x2142 modify the startup configuration key reload reload Router ( restart ) End directly returns to privileged mode Ways allow different protocols to alternate Using private IP addresses host , you can not directly access the public network (Internet) private IP public network router will not appear in the routing table . Apply application related configuration Interface Serial1 no ip address Source : 10.3.3.1 First, a one-way virtual control connection (VCC) established by a LES to an LEC in the ATM . Usually, the VCC expedited delivery ( accelerated delivery ) may be the same or other layers of protocol of a different network device in There are multiple links on the same network, and STP will shut down - ports to block network loops. 1 1 2 1 2 1 choke packet ( packet that was blocked ) when congestion exists, it is sent to the sender of a packet, it should inform =========================================================== =============== HDLC: BGP4 BGP Version 4 (BGPversion4) ----- versions of the most common on the Internet inter-domain routing protocol 4 . The higher the RouteID, the easier it becomes to become a DR (Designated Router designated router ) access. Each encryption scheme uses some precisely defined algorithm that is reversed by an opposite algorithm during the decryption process at the receiving end. BECN between the Explicit Congestion through-pipe (Backward Explicit Congestion Notification) BECN is Serial1 is down, Line protocol is down clear ip route * clear route table Programmable after shipment, these non-volatile memory chips can be wiped off and reprogrammed with high power light when needed. See EEPROM and PROM . Show spanning-tree interface fastEthernet 0/23 View the status of the interface in the spanning tree If the router has a loopback interface , select the highest IP from the loopback interface as the RouterID. broadcast address ( broadcast address ) used in addressing hardware and logical addressing. In logical addressing, the host Exit application and exit the database configuration mode of the VLAN B(config)#ip nat inside source list 1 interface serial 1 overload =========================================================== =============== Standard access control list : Detect only the access control list of the source address extension : source address ,ine ccie security v5 technologies, destination address , protocol , port number Show controllers serial 0 is used to view the attributes of DCE and DTE HDLC Advanced Data Link Control----- Use frame characters ( including checksums ) , Spanning-tree vlan 1 priority ? Modify the priority of the switch to change the cost cost of the interface GRE Generic Routing Encapsulation (Generic Routing Encapsulation): Cisco utilizing TP a tunneling protocol to create a tunnel protocol packet encapsulated in various types of capabilities, thereby producing a virtual point to point connection, a connection across the IP network connection Go to the remote Cisco router. 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.
