OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S3
CSCed53358
Symptoms: Pings fail on an Ethernet-to-VLAN interworking over L2TPv3 due to an IRDP failure.
Conditions: This symptom is observed when you ping between two CE routers. Both of the CE
routers do not learn each other’s MAC address automatically.
Workaround: Ping from the first CE router to the second CE router, then ping from the second CE
router to the first CE router.
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.
CSCed60800
Symptoms: The withdraw message of a multipath (not bestpath) from a BGP neighbor deletes the
path from the BGP table but it does not uninstall the route from the IP routing table.
Conditions: This symptom is observed when the maximum-paths eibgp command or
maximum-paths ibgp command is configured.
Workaround: Enter the clear ip bgp * or disable the maximum-paths eibgp command or
maximum-paths ibgp command.
Alternate Workaround: if the number of possible EBGP peers are less or equal to 2 then the problem
is transient and not obviously noticeable.
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.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0S, 12.2S,
or 12.3T.
Workaround: There is no workaround.
CSCee24899
Symptoms: A router that is configured for multicast routing may reload due to a bus error.
Conditions: This symptom is observed on a Cisco router that runs a Cisco IOS software release that
contains the fix for CSCec80252. A list of the affected releases can be found at
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCec80252. Cisco IOS
software releases that are not listed in the “First Fixed-in Version” field at this location are not
affected.
Workaround: There is no workaround.
