Resolved Caveats—Cisco IOS Release 12.0(28)S1
IP Routing Protocols
• CSCds67028
Symptoms: A Cisco 7200 series router may reload with a bus error in ipigrp2_ager.
Conditions: This symptom can occur while the router is running Enhanced Interior Gateway Routing
Protocol (EIGRP).
Workaround: There is no workaround.
• CSCed33044
Symptoms: ARP may not function properly on the remote side of point-to-point Fast Ethernet link
with a default static route until the remote side is pinged.
Conditions: This symptom is observed on a Cisco router when ARP and /31 mask are configured on
a point-to-point link Fast Ethernet link with a default static route. The symptom is
platform-independent.
Workaround: There are four different workarounds:
– Use a /30 netmask on the point-to-point Fast Ethernet connection.
– Configure a static ARP entry for the remote side of the Fast Ethernet link.
– Enter the ip proxy-arp command on the remote side of the Fast Ethernet link.
– Use an OSPF route instead of a default static route.
• CSCed57403
Symptoms: When a Cisco router is a midpoint of a TE tunnel and the tunnel headend is a third- party
vendor router, the Cisco router may crash.
Conditions: This symptom is observed during a period of network instability and may occur when
a TE tunnel does not contain an EXPLICIT ROUTE object and when the tunnel is dynamically
routed by using OSPF cost only.
Workaround: Use an EXPLICIT ROUTE object or ensure that there are no alternate paths in the
network.
• CSCed59978
Symptoms: A router may crash and reload due to a bus error, and the following error message may
appear:
Unexpected exception, CPU signal 10
Conditions: This symptom is observed on a Cisco router that is running OSPF and that is configured
for incremental SPF.
Workaround: Remove incremental SPF from the router by entering the router ospf process-id
command followed by the no ospf command.
• CSCed86069
Symptoms: A software-forced chunk corruption crash may occur when a MALLOC failure occurs.
Conditions: This symptom is observed on a Cisco platform that has the bgp dampening command
enabled.
Workaround: There is no workaround.
• CSCed93630
Symptoms: A Cisco router may reload unexpectedly when a bgp debug command is enabled.
