To verify the configuration:
• Enter the show ip route command to confirm that the static route is installed and pointing at your
dialer map address. The static IP default route must first be configured before you enter this
command.
robo-austin# show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default
U - per-user static route, o - ODR
Gateway of last resort is 10.1.254.1 to network 0.0.0.0
10.0.0.0/24 is subnetted, 2 subnets
C 10.1.4.0 is directly connected, Ethernet0
C 10.1.254.0 is directly connected, BRI0
S* 0.0.0.0/0 [1/0] via 10.1.254.1
Note The static route is the first software building block (design crux) that receives the packet
routed to the dialer map. The route must direct the packets to at the dialer map before the DDR
features can establish connectivity.
• Enter the show dialer command. The following example shows that the Cisco 1604 has not
placed any calls yet, and there have been no failures. An ISDN interface is a dialer interface.
Key statistics are shown for each B channel.
robo-austin# show dialer
BRI0 - dialer type = ISDN
Dial String Successes Failures Last called Last status

0 incoming call(s) have been screened.

robo-austin(config) ip route 0.0.0.0 0.0.0.0 10.1.254.1 permanent
Create a static route for the next hop,
which is the Cisco AS5300’s WAN port.
IP address 10.1.254.1 is used on the
Cisco AS5300’s dialer interface.
This static route points at the dialer map
on the access server’s dialer interface.

robo-austin(config)# username hq-sanjose password austin-pw
When the Cisco AS5300 (hq-sanjose)
authenticates the Cisco 1604 using
CHAP, this password will be used by the
Cisco 1604

.

robo-austin(config)# ip classless
Ensure that all unknown subnets use the
default route.
1. On Cisco IOS devices the PPP name is determined by one of the following commands: hostname, sgbp group, ppp pap sent-username,orppp chap hostname.
