Cisco3640 vro settings

1. Set vro Management Information
1. Connect the 9-hole connector with the flat control line, connect the CONSOLE to the terminal or PC serial port, and set the parameters of the terminal or the Super Terminal directly connected to the serial port: the BAND rate is 9600, no parity, 8-Bit Data bit, 1-bit stop bit.
2. When the router is powered on, the terminal screen displays the power-on process.
3. Set the password in privileged Mode

Ii. CISCO router Wan Configuration Wizard
1. dial-on demand routing (ddr) is a network connection provided by a public telephone network. Generally, most WAN connections use leased lines. routers connect to DCE devices similar to modem or isdntas. They support synchronous V.25BITS protocol. You can use the scripts and dialer commands to set the dial-up string.
DDR is suitable for scenarios where the user's log rate is not high and sometimes there is data transmission or data is transmitted only at a specific time, such as when the bank transfers reports every night.
When a packet arrives at the vro, a DDR request is generated. The vro sends the call establishment information to the DCE device of the specified serial port, this call connects the local device to a remote device. Once no data is transmitted, the idle time starts to record the time. The connection is terminated when the specified time is exceeded. DDR now uses static routes to transmit data, avoiding DDR dialing caused by route switching.
And XNS can be configured to one or more destinations through DDR routing addressing, synchronous serial port, asynchronous serial port and ISDN port.
Below is a typical DDR connection:
In the DDR configuration process, we can configure one or more physical ports as a logical dialing interface, which can be synchronous to V.25 mode, synchronous to DYR to start dialing or asynchronous CHATSCRIPT mode.
In Port Configuration Mode:
Activate DIAL-ON-demand routing on a port
Command: dialer in-band
Specify a port as a dial-up access group: dialer-group-number
Specify a single phone number: dialer string dialer-string
Unprecedented waiting time before disconnection: dialer idle-time seconds
Define one or more target phone numbers:
Dialer map protocol net-hop-address dialer-string
Restrict the transmitted access-list table or specific protocol:
Dialer-list dialer-group list access-list-number or
Dialer-list dialer-group protocol name (permit/deny/list access-list-number)
