There are two channelized E1 interfaces on cisco 4500. The port bandwidth is 2 M, which is a channelized E1 port with time slot. Each E1 port can be divided into 30 time slots. The bandwidth for each time slot is 64 KB.

There are three types of interfaces: ANSI: T1.617; CCITTY: Q933A and CISCO-specific standards. # Fram-relay intf-typ ABC ABC is the frame relay device type. They are DTE devices, DCE switch or NNI network contact interface. # Frame_relay interface_dlci 110 br Configure the DLCI (data link connection identifier ). # Frame-relay map ip abcd xxxx broadcast Creates a frame relay ing. ABCD is the peer IP address. XXXX indicates the local DLCI number and broadcast. Allow forward or update routing for broadcast. # No shutdown Activate this port. # Exit
|
5. Configure the Frame Relay subinterface
# Conf t # Int s0.1 point-to-point Corresponding to S0 sub-interface 1, point-to-point mode. # Ip addr ABCD XXXX ABCD is the IP address of sub-Port 1, and XXXX is the subnet mask. # Frame-relay intreface-dlci 100 br

6. Configure dial-up backup
(1) configure the backup Main Port
# Conf t # Int s0 S0 is the main port. # Backup int asy 1 A1 port is the backup port. # Backup delay 0 1 1 second delay.
|
(2) Configure virtual Interfaces
# Conf t # Ip addr ABCD XXXX ABCD is the virtual interface IP address, and XXXX is the subnet mask. # Encap ppp Encapsulate the ppp protocol. # Dialer in-band Activate the call and dial function. # Dialer idle-timeout 7200 # Dialer map ip ABCD modem-script call The dial port corresponding to the broadcast 6225481 br ing. ABCD is the IP address of the Peer dialing port, and 6225481 is the corresponding phone number. # Dialer_group 1 defines the dial-up group members.

(3) configure the firewall
# Dialer_list 1 pro ip permit Allow the IP protocol to pass.
|
(4) configure the connection password
# User name ABCD pass XXXX ABCD is the host name of the other party, and XXXX is the connection password.

|
8. Dynamic Route Configuration
# Conf t # Router VPN 20 Use the network routing protocol. Common routing protocols include RIP, IGRP, and IS-IS. # Passive-interface serial0 If S0 is connected to X.25, enter this command. # Passive-interface serial1 If S1 is connected to X.25, enter this command. # Network ABCD ABCD is the local ethernet address. # Network XXXX The IP address where XXXX is S0. # No auto-summary # Exit
|
9. Static route Configuration
# Ip router abcd xxxx yyyy 90 ABCD is the ethernet address of the Peer router; XXXX It is the subnet mask. YYYY is the WAN port address corresponding to the other party. # Dialer-list 1 protocol ip permail

10. Back up the configuration file to the hard disk
Create an empty file on the hard disk and have the read and write permissions.
11. Restore the backup configuration file to the vro
12. Create a backup on the vro
Vro has many configuration parameters, which can be increased or decreased as needed.
Iii. Commissioning
1. Activate the Ethernet port of the vroethernet and all the serial ports to be used by entering the port and executing No Shutdown.
2. add the Ethernet address of the default router in the host connected to the router: routeradd defaule XXXX 1 XXXX is the E0 address of the router ). A default route must be added to each host. Otherwise, communication will fail.
3. ping the Ethernet network port of the local router if it fails: 1) The Ethetnet network port is not activated; 2) it is not on the same network. If the wide-area network port is disconnected: no default route is added: router configuration error), if the router Ethernet port is disconnected: the router is configured incorrectly), if the host Ethernet port is disconnected: The other host does not add the default route ).
4. add a static gateway route on the primary machine of the leased line card (X.25). The method is to execute: router add X. x. x. X Y.Y. y.Y 1. X. X indicates the Ethernet address of the peer network, and Y.Y. Y.Y indicates the WAN address of the peer network.
5. Use Tracert to track the route to determine the CIDR block.
