Configuration 1, configuring DDR Dial-On-Demand Routing (DDR) is a network connection with public telephone network. Usually, the wide area network is connected by a special line, the router is connected to the data terminal DCE device similar to Modem or ISDN TAS. On, they support the synchronous V.25bis protocol, you can set the dial string with the Scripts and Dialer commands. DDR compares the user's alignment requirements, occasionally data transmission or just transmit data at a specific time, such as banks per night In the case of the transmission report, when an interested package reaches the router, a DDR request is generated. The router sends a call setup information to the specified serial port DCE device. This call connects the local and remote devices. Once there is no data Transmission, idle time starts timing, exceeding the set idle time, this time connection termination. DDR now uses static routes to transmit packets, avoiding DDR dials caused by routing exchange .appletalk, Banyan Vines, Clns, DECNET, IP, IPX, And XNS can be addressed by DDR. Synchronous serial port, asynchronous serial port, and ISDN ports can be configured to one or more destination DDR connections. In the configuration DDR process, we can configure one or several physical interfaces into a logical dial Interface, it can be synchronized V.25, synchronous DTR start dial or asynchronous Chat Script mode. In port configuration mode: function command activates Dial-on-Demand Routing Dialer in-band on one port to specify a port for dial-up access Group Dialer-Group Group-Number Specifies a single phone number Dialer String Dial-String Front Overline Free Waiting Time Dialer IDLE-TIME Seconds Defines One or more destination phone number table Dialer Map protocol net-hop-address Dialer-String Limited Transmission Access-List table or specific protocol Dialer-list dialer-group list access-list-number or dialer-list dialer-group protocol protocol-name {permit | deny | list accept ss-list-number} in Dialer String and Dialer Map Two commands are optional, Dialer String is used when there is only one phone number, and the Dialer Map is a telephone number table. Details For details, please refer to an instance of "DDR Example" below. Configure dial-up backup dial backups provide a protection so that when the radiopolline on the WAN is faulty, start a backup line to make communication normally. There are two cases of startup backup. : The main line breaks off the transmission traffic exceeds the defined maximum value. The definition is required as follows: Set its backup port on the main line port Backup Interface Interface-Name Define Backup Load Backup Load {Enable-Threshold | Never} {Disable-load | Never} Defines the response time of the main trunk up or DOWN. BACKUP DELAY {Enable-delay | Never) {Disable-delay | Never} where the main trunk exceeds the total transfer amount, start the backup line disable -Load --- indicates that the transmission amount is reduced to disconnect the backup line. Enable-delay --- After the main trunk is disconnected, start the backup line. Disable-delay --- indicates that the main line is re-re- After the recovery, the backup line is disconnected. 2, configuring the frame relay frame relay is a protocol standardized by ANSI and CCITT, which provides today's sudden business traffic (such as LAN interconnect and SNA service) Significant performance price advantage. Frame relay is a client device (CPE), such as a router or front-end processor, and a network protocol between a wide area network that sends data to the remote CPE. It has the following features: low Delay, delay refers to the time for a given to send frame through the network to the remote user equipment. When the network is increased, the performance will fall;
Especially for sensitive protocols such as SNA and DECNETs, all frames must wait for a protocol (ie, Novell IPX) that must be awaited after sending, and the use of short trading types. Reliability, under a given delay condition, throughput with the network The reliability varies, the reliability is good, the timeout wait for the resend, the throughput will greatly increase. Lower networked overhead can be predicted in many network environments, such as SNA CICS, not only demand, not only And need to be predictable. Fair. Cisco '

END 6, Configuring PPP: PPP (Point-to-Point Protocol) is the successor of SLIP (Serial Line IP Protocol), which provides a router to Router-to-Router and hosts across synchronous and asynchronous circuits. Network (Host-to-Network) connection. Chap (Chapter Handshake Authentication Protocol) and PAP (PaP (PassWord Authentication Protocol) (PAP) are often used to provide security authentication on serial lines of PPP packages. With CHAP and PAP authentication, each router recognizes the name to prevent unauthorized access. CHAP and PAP have a detailed description on the RFC 1334. A.

The documentation shows RFC1058, RFC1723. RIP switches routing information through broadcast UDP packets, and sends a routing information update every 30 seconds. RIP provides a hop count as a scale to measure routing distance, and the jump count is a number of routers that must be passed by a package to reach the target. If there is two routers that do not equally or different bandwidths, the jump count is the same, then the RIP believes that the two routes are equal. RIP supports up to 15, that is, the number of most routers to pass through the source and destination network is 15, and the number of hops is not reached. 1.

Use a combined user configuration scale, including delay, bandwidth, reliability, and load.
By default, IGRP sends a route update broadcast every 90 seconds, within 3 update cycles (ie 270 seconds), no route is not accessible from the first router from the routing. After 7 update cycles, 630 seconds, Cisco IOS software clears the route from the routing table. 1. The command task command specifies that the network network network network NETWORK connected to the router is specified using the RIP protocol Router IGRP AutoMous-System1 to specify the NEIGHBOR IP-Address Note: 1. Autonomous-System can be built freely, not actually AUTONOMOMOMOMSTEM, but the router running IGRP wants to swap routing update information It is the same as the autonomous-system. 2.

III, OSPF protocol OSPF (Open Shortest Path First) is an internal gateway protocol (IGP) for an internal gateway protocol (IGP) for an Internal Gateway Protocol, which is used in a single autonomous system (Autonomous System, AS) internal decision route. With RIP, OSPF is a link state routing protocol, and RIP is a distance vector routing protocol. The link is another statement of the router interface, so OSPF is also called an interface status routing protocol. OSPF creates a link status database through the status of the network interface between the router, generates the shortest path tree, and each OSPF router uses these shortest path to construct the routing table. 1. The Command Global Setup Task Command Specifies the NETWORK ADDRESS WILDCARD-MASK Area Area-Id2 that is connected to the router using the OSPF protocol Router OSPF Process-ID1 Specifies the NEIGHBOR IP-Address Node Address Node Address Note: 1, OSPF Routing The process process-id must specify the range 1-65535, multiple OSPF processes can be configured on the same router, but it is best not to do. Multiple OSPF processes require a copy of multiple OSPF databases that must run a copy of multiple shortest path algorithms. The Process-ID only works within the router, and the Process-ID of different routers can be different. 2, Wildcard-Mask is the counter code of the subnet mask, the decimal number of the network area ID area-ID in 0-4294967295, or X.x.x.x with IP address format. When the network area ID is 0 or 0.0.0.0, it is the main domain. The routers of different network areas are routing information through the main sanctuary.

Using Authentication For security reasons, we can be in the same OSPF area The function of authentication is enabled on the router, and only the router of the same area of authentication can be notified to each other. By default, OSPF does not use zone verification. Authentication feature, plain text authentication and message summary (MD5) authentication can be enabled by two ways. Plain text authentication The authentication password is plain text, which will be determined by the network detector, so it is not safe, not recommended. And Message Summary (MD5) Authentication To encrypt your password before transferring authentication password, so it is generally recommended to use this method for authentication. When using authentication, all router interfaces in the area must use the same authentication method. For the trial authentication, you must configure the password for each router interface for the area in the router interface configuration mode. Task Command Specify Authentication Area Area-ID Authentication [Message-Digest] Using plain text authentication IP OSPF Authentication-Key Password Using Message Summary (MD5) Authentication IP OSPF Message-Digest-Key Keyid MD5 Key The following verification settings The example, the example network distribution and address allocation environment are the same as those of the above basic configuration, just in the area 0 of Router1 and Router2, using authentication functions.

Debug ip ospf adj Debug IP OSPF Events 4, reassigned routing in actual work, we will encounter networks using multiple IP route protocols. In order to make the entire network work normally, a successful route must be reassigned between multiple routing protocols. The following is listed below to reassign the Route in OSPF and RIP: Router1's Serial 0 port and Router2's Serial 0 port runs OSPF, running RIP 2, Router3 running RIP2, Router2, is Router4, and Router2 is 192.168. 2.0 / 24 static routes of the network, Router4 uses the default static route. You need to redistribute OSPF and RIP routing between Router1 and Router3, reassign the static route and direct routes on Router2.

IPX protocol Setting IPX protocol and IP protocols are two different network layer protocols, and their routing protocols are different. IPX's routing protocol is not like IP's routing protocol. Therefore, it is relatively simple. However, the IPX protocol must specify the package in the Ethernet.
