Idle timer (120 secs), Fast idle timer (20 secs)
Wait for carrier (30 secs), Re-enable (15 secs)
Dialer state is idle
4. What is the idle timer set to for both BRI0/0:1 and BRI0/0:2?

Step 4
Now configure the Capetown router. The steps to accomplish this are basically the same as Steps 2
through 3. Therefore, complete the following:
Capetown(config)#isdn switch-type basic-ni
Capetown(config)#username SanJose1 password cisco
Capetown(config)#enable password cisco
Capetown(config)#line vty 0 4
Capetown(config-line)#password cisco
Capetown(config-line)#login
Capetown(config-line)#exit
Capetown(config)#interface bri0/0
Capetown(config-if)#ip address 192.168.16.3 255.255.255.0
Capetown(config-if)#encapsulation ppp
Capetown(config-if)#ppp authentication chap
Capetown(config-if)#dialer-group 1
Capetown(config-if)#isdn spid1 51055520000001 5552000
Capetown(config-if)#isdn spid2 51055520010001 5552001
Capetown(config-if)#dialer idle-timeout 60
Capetown(config-if)#dialer map ip 192.168.16.1 name SanJose1 5551000
Capetown(config-if)#no shutdown
Capetown is a stub network. All traffic destined for other networks other than its own should be
forwarded to SanJose1. For this reason, enter a default static route on Capetown pointing to
SanJose1 as follows:
Capetown(config)#ip route 0.0.0.0 0.0.0.0 192.168.16.1
Finally, to test and confirm connectivity between both sites, configure a more permissive dialer-list as
follows:
Capetown(config)#dialer-list 1 protocol ip permit
Once connectivity has been confirmed between the two routers, a more restrictive dialer-list will be
configured on Capetown.
Step 5
Test the ISDN connection. Before bringing up the ISDN link, enable debugging on both routers. This
will allow for troubleshooting more efficiently in the event problems are encountered. Issue the
following command to view dialer information on both routers:
SanJose1#debug dialer
ISDN may need to be debugged with the following command:
Sa
nJose1#debug isdn events
