Symptoms: A PSTN Gateway unexpectedly restarts due to a lack of memory. Overtime memory
utilization increases, and the show processes memory sorted command indicates that the ISDN
process is allocating an increased amount of memory.

Conditions: This leak occurs when a SETUP message with Display IE is received.
Workaround: There is no workaround.

Symptoms: When a Multilink PPP (MLP) session is established over an ISDN link, IPCP fails to
negotiate. When the debug ppp negotiation command is enabled, you can see that IPCP packets
from the peer are not processed. The output of the show interface command for the ISDN D-channel
interface shows that the input queue limit is 0.

interface shows that the input queue limit is 0.
Conditions: This symptom is observed when the ISDN BRI or PRI interface is not configured as part
of a dialer rotary group or dialer pool and when RADIUS is used to assign the multilink bundle to
a VRF.

Conditions: This symptom is observed on a Cisco 7200 router that is configured for MLP-PPP.
Workaround: Shut the multilink interface before doing an OIR.

Symptoms: When BRI interface flaps rapidly, ISDN Layer 1 detects link down, but Layers 2 and 3
keep active state during the transition. This may cause the BRI interface to get stuck, where
subsequent incoming/outgoing call is rejected.

Conditions: The symptom may be observed when cable is pulled out and put back rapidly.
Workaround: Issue the clear interface command or the shutdown command followed by the no
shutdown command on the affected BRI interface.
