Resolved Caveats—Cisco IOS Release 12.0(28)S4
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the ATM interface of the PA-A3 port adapter.
• CSCsa87986
Symptoms: A router may intermittently transmit corrupt PPP packets. When you enter the debug
ppp nego and debug ppp errors commands, it appears that “protocol reject” packets are received
from the remote end.
Conditions: This symptom is observed on a Cisco 7500 series that has only one OC3 POS port
adaptor per VIP and that is configured for PPP encapsulation.
Workaround: There is no workaround.
IP Routing Protocols
• CSCdz42920
Symptoms: A router may crash because of a bus error when you configure IP accounting.
Conditions: This symptom is observed when you enter the clear ip accounting EXEC command.
Workaround: Do not enter the clear ip accounting or show ip accounting EXEC command.
• CSCea31201
Symptoms: A Cisco router may reload unexpectedly because of a bus error.
Conditions: This symptom is observed on a Cisco router that has the ip accounting interface
configuration command enabled.
Workaround: There is no workaround. The problem is rare and typically not reproducible.
• CSCeg54375
Symptoms: Routing inconsistencies may occur in the RIB: routes may be missing from the RIB but
may be present in the BGP table.
Conditions: This symptom is observed on a Cisco RPM-XF when the toaster processor crashes.
However, the symptom may occur on any platform that has a toaster processor.
Workaround: Enter the clear ip route vrf vrf-name * command.
• CSCeg89700
Symptoms: A Cisco router does not recognize an end-of-RIB message from a third-party vendor
router and continues to show the “Neighbor is currently in NSF mode” message although the restart
procedure of the third-party vendor router is complete.
Conditions: This symptom is observed on a Cisco router that is configured for IPv6 BGP peering
and NSF. Note that the symptom does not occur when IPv4 BGP peering is configured.
Workaround: There is no workaround.
• CSCeh16989
Symptoms: The Multiprotocol BGP (MP-BGP) network entries counter increases above the real
number of reachable networks.
Conditions: This symptom is observed when network activity occurs in a non-converged
environment. The correct number of network entries is restored when there is a period of BGP
stability that last for about 1 minute or more because BGP is able to converge and the scanner has
time to run and collect the old network entries. However, if there is a sustained period of churn and
