Quidway(config-if-Bri0)# ip address 100.1.1.2 255.255.255.0

Quidway(config-if-Bri0)# dialer map ip 100.1.1.1 8810152
IV. Check whether dialer-list is configured correctly
DDR specifies whether to dial and send one packet sent to the dial interface, according
to the dialer-list corresponding to the dialer-group configured b y the user. If the packet
is out of dialer-list range, then DDR will send the packet if the link to send th is packet is
existing, otherwise DDR discard this packet. That is, DDR will not automatically
perform dial connection for packets beyond dialer-list range.
As shown in the following example 1, dialer-list is incorrectly configured as deny IP
packet, in this case, DDR will not create call dial connection for IP pack et on the
corresponding dial port. Example 2 presents the correct configuration.
Example 1: incorrect DDR configuration, dialer-list configuration error (bold-typed part).
Quidway(config)# dialer-list 1 protocol ip deny
Quidway(config)# interface bri 0
Quidway(config-if-Bri0)# ip address 100.1.1.2 255.255.255.0
Quidway(config-if-Bri0)# dialer-group 1
Quidway(config-if-Bri0)# dialer map ip 100.1.1.1 8810152
Example 2: the modified correct DDR configuration (the bold-typed part)
Quidway(config)# dialer-list 1 protocol ip permit
Quidway(config)# interface bri 0
Quidway(config-if-Bri0)# ip address 100.1.1.2 255.255.255.0
Quidway(config-if-Bri0)# dialer-group 1
Quidway(config-if-Bri0)# dialer map ip 100.1.1.1 8810152
V. Check whether the configuration for PPP authentication is correct
Under the Dialer Profile configuration, if the local end requires receiving incom ing cal l,
then PPP authentication must be configured at both local and remote end, and at both
dialer and physical interface. If the PPP authentication configuration is incorrect, or if
the remote name consulted through PPP is different from the remote-name of DDR
configuration, there will be no interworking between the two ends. PPP authentication
configuration error may be caused by one of the following factors:
z The user-name is not configured, causing the failure of ppp consulting.
z The ppp authentication is not configured, so that PPP fails to reques t nam e f rom
the remote to be used by DDR.
z The ppp authentication pap is configured, but there is error in ppp pap sent-
username configuration, causing the failure of ppp consulting.
z The ppp authentication chap is configured, but there is error in ppp chap host
configuration, causing the failure of ppp consulting.
