Versatile Routing Platform

DDR Configuration

zAdd in the remote router, the dialer map corresponding to local router network layer address.

zRemove 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.
