Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: The symptom is observed on a Cisco 10000 series router that is running Cisco IOS
Release 12.2(33)SB1.
Workaround: There is no workaround.
Further Problem Description: The occurrence of the problem so far has been rare. The decode of the
traceback points to a BGP issue. The confirmation of whether a crash is due to this bug in BGP or
not can only be made after the traceback from the crash has been decoded by Cisco support
engineers.

Symptoms: Redistributed routes are not being advertised after a neighbor flap.
Conditions: This symptom is observed if BGP is redistributing local routes and if there are multiple
neighbors in the same update-group and then a neighbor flaps. For the flapped neighbor, some
redistributed routes are not being advertised.
Workaround: Undo and redo the redistribution.

Symptoms: Changing any of the parameters of a route-map does not take effect.
Conditions: Occurs when using a BGP aggregate-address with an advertise map.
Workaround: Delete the aggregate-address statement and then put it back for the change to take
effect.

Symptoms: A router configured with BGP import from the global IPv4 table into a VRF using the
VRF configuration command import ipv4 unicast map ... may exhibit a brief traffic outage to
destinations reached through the imported routes following a switchover.
Conditions: Global to VRF import must be configured under the VRF. Issue only affects Cisco IOS
Release 12.29(33)SR releases.
Workaround: There is no workaround.

Symptoms: Frame-Relay fragment output not seen when modifying the attached map-class.
Conditions: Occurs on a Cisco 7200 router.
Workaround: Detach and attach Frame-Relay fragment.
• CSCsu72059
Symptoms: After multiple OIRs, memory gets fragmented in line card and at one stage the mallocs
start failing.
Conditions: There is a higher chance of fragmentation when we have ATM OC3 SPAs in both the
bays and huge configurations which eat up lot of memory.
Workaround: Reload the line card.
