DDR Configuration

z Add in the remote router, the dialer map corresponding to local router network
layer address.
z Remove all the dialer maps in the remote configuration, and use dial string
instead.
DDR: link negotiation Down on interface ***
This debugging information may be generated by the following causes: incorrect PPP
configuration, so that PPP consulting fails and thus the connection is hooked on.
The solution is: configure with reference of the example above.
DDR: NAME authentication ERROR failed
This debugging information may be generated by the following causes: the name
(dialer remote-name, name in dialer map) configured by DDR is inconsistent with the
name configured in PPP, local DDR authentication fails to pass thus this connection is
hooked on.
The solution is: configure with reference of the example above.
DDR: peeraddr matching error on interface *** shutdown link
This debugging information may be generated by the following cause: there is no
remote network layer address in the local dialer map.
The solution is: add in the local router, the dialer map corresponding to remote network
layer address, or remove all the dialer maps in the local configuration, and use dial
string instead.
DDR:idle-timeout on interface *** shutdown! start enable-time
This debugging information does not indicate any error, instead, it means that the local
DDR idle-timeout time is timeout and DDR hooks on the connection normally.
DDR: wait-for-carrier-timeout on a link on interface *** shutdown!start
enable-time
This debugging information may be generated by the following cause: local router fails
to dial and connect the opposite end, because the opposite end is busy or telephone
line quality is poor.
DDR: The interface has no dialer-group discard the packet!
This debugging information may be generated by the following cause: dialer-group
configuration command is not configured on the corresponding logical dial interface or
on the physical port directly enabling DDR.
The solution is: configure with reference of the example above.
DDR: there is not a dialer string on the interface failed discard packet
This debugging information may be generated by the following cause: dialer-map is not
configured on the corresponding logical dialer interface or on the physical port directly
enabling DDR, and no dial string is configured.
The solution is: configure dialer map and dial string locally according to the calls to be
sent by local end.
DDR: Enable-timeout is effective failed
This debugging information does not indicate any error, instead, it is because that the
enable-timeout timer of the corresponding physical port is not yet timeout. When the
timer is timeout, the corresponding physical port can be used to dial.
