Cisco Cisco IOS Software Release 12.4(4)T

Workaround: There is no workaround.

CSCek74474

Symptoms: When you enter the protocol ip protocol-address broadcast command on an ISP 
termination point, the command may not be applied to a connected CPE, preventing the CPE from 
populating its ARP cache and from properly forwarding traffic.

Conditions: This symptom is observed on a Cisco router that functions as an ISP termination point 
and that is configured for point-to-point ATM connections when a connected CPE is configured for 
multipoint-to-point ATM connections.

Reason: Command is not applied until VC recreated or bounced.

Workaround: Configure the protocol ip protocol-address broadcast command as part of a PVC 
configuration on the CPE.

Alternate Workaround: Configure the connection between the ISP termination point and the CPE as 
a multipoint-to-point ATM connection.

Symptoms: A router that is running Cisco IOS Release 12.4T may reload unexpectedly. 

Conditions: Occurs when BFD is configured and active.

Workaround: Disable the BFD feature. 

CSCek76288

Symptoms: With MLPoATM configured, a router crashes when using the show ppp multilink 
command after disabling the PA by the hw-module slot slot-number stop command.

Conditions: This symptom has been observed on a Cisco 7200 NPE-G1 loaded with Cisco IOS 
interim Release 12.4(13.13)T2.

Workaround: There is no workaround. 

CSCek77424

Symptoms: A Cisco router that is running Cisco IOS Release 12.4(13b) might unexpectedly reload 
with a bus error.

Conditions: This symptom happens during normal operation with NAT configured.

Workaround: There is no workaround. 

CSCek78237

Symptoms: A short CPU hog seen in the ATM PA Helper process when an interface flaps and the 
framing configuration is modified on the interface.

Conditions: This symptom is observed on a Cisco 7200 with a PA-A3-T3 adapter that is running 
Cisco IOS Release 12.2(25)S or 12.2(31)SB (and possibly other Cisco IOS releases).

Workaround: There is no workaround.

Further Problem Description: The CPU hog is enough to cause OSPF adjacencies (with fast hello) 
to go down on other unrelated interfaces. The same problem is seen if BFD is configured. 

CSCek78330

Symptoms: A router that is configured with ATM PVCs may generate the following type of error 
messages:

%COMMON_FIB-3-FIBIDBINCONS2: An internal software error occurred. Virtual- Access2.1 

linked to wrong idb Virtual-Access2.1

Conditions: This symptom is observed on a Cisco router that has virtual-template subinterfaces.
