6-2 Dial Solutions Quick Configuration Guide
Configuring the Answering Access Server
Note Names are case sensitive, so be sure that both the dialing and answering access servers use
the same capitalization and spelling.
Perform the steps in the following procedures to configure the answering access server (Snoopy).
The configuration is broken into procedural components (routing in global configuration mode, the
Ethernet interface, asynchronous interfaces, security, and so on).
Defining Modem Parameters
Perform the following steps to configure modem support for an access server answering DDR calls
(Snoopy):
Step 1 Configure the line speed. In the following example, line speed is set to 115200 bps. If you
are configuring dialin on an AUX port, the maximum speed is 38400 bps.
Snoopy(config)# line tty 1
Snoopy(config-line)# speed 115200
Step 2 Configure flow control on the line accepting the incoming DDR call.
Snoopy(config-line)# flowcontrol hardware
Step 3 Because the answering access server is taking incoming calls on line 1 only, configure the
modem to accept incoming calls on that line.
Snoopy(config-line)# modem dialin
Note You cannot establish a reverse Telnet session to the modem attached to line 1 if the modem
dialin command is used. To use reverse Telnet, you must use the modem inout command. After a
reverse Telnet session is completed, you can reissue the modem dialin command.
Configuring Routing and a Routing Protocol
Perform the following steps to configure RIP routing on the access server answering DDR calls
(Snoopy).
Step 1 Configure RIP routing globally on the access server answering DDR calls (Snoopy):
Snoopy(config)# router rip
Snoopy(config-router)#
Step 2 Associate a network to the RIP routing process:
Snoopy(config-router)# network 172.16.0.0
Snoopy(config-router)# exit
Snoopy(config)#
Step 3 Create a static default route. A static default route is required because routes that are
resolved dynamically are lost when the DDR link is down. If the access server receives a
packet that is destined to a network not listed in its routing table, the access server
forwards this packet to the access server on the other side of the dialup link (in this case
to 172.16.20.1), which is the address of the opposite access server (Woodstock).
Snoopy(config)# ip route 0.0.0.0 0.0.0.0 172.16.20.1
