Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S6
Conditions: This symptom is observed rarely when all of the following conditions are present:
–
There is a very brief (shorter than 500 ms) interface flap on a point-to-point interface such as a
POS interface.
–
The flap is not noticed by the neighbor, so the neighbors interface remains up.
–
The OSPF adjacency goes down and comes back up very quickly (the total time is shorter than
500 ms).
–
OSPF runs an SPF during this period and, based on the transient adjacency information,
removes routes via this adjacency.
–
The OSPF LSA generation is delayed because of LSA throttling. When the LSA throttle timer
expires and the LSA is built, the LSA appears unchanged.
Workaround: Increase the carrier-delay time for the interface to about 1 second or longer.
Alternate Workaround: Use an LSA build time shorter than the time that it takes for an adjacency to
come up completely.
• CSCsd03383
Symptoms: A route is not installed through an MPLS TE tunnel even though the tunnel mpls
traffic-eng autoroute announce command is enabled.
Conditions: This symptom is observed on a Cisco router that also has the mpls traffic-eng
multicast-intact command enabled.
Workaround: There is no workaround.
• CSCse65214
Symptoms: An RSVP Reservation message may be delayed.
Conditions: This symptom is observed on a Cisco router when an RSVP session is set up.
Workaround: There is no workaround.
Miscellaneous
• CSCef08173
Symptoms: A VIP in which a PA-2FE port adapter is installed may reload because of memory
corruption that is caused by a hardware issue of the PA-2FE port adapter.
Conditions: This symptom is observed when the VIP and port adapter function under stress, when
the VIP is unable to serve memory read/write requests from the port adapter, and when there are PCI
retry timeouts.
Workaround: There is no workaround.
• CSCeg30179
Symptoms: Removing a policy that has shape and bandwidth in the same class (in that same order)
may cause a router to crash.
Conditions: This symptom is observed when the router functions under a traffic load.
Workaround: There is no workaround.
• CSCeh29183
Symptoms: When you configure MPLS Traffic Engineering AutoTunnel Mesh Groups by entering
the following commands, many FIB messages and tracebacks are generated:
