Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: In a network with redundant topology, an Open Shortest Path First (OSPF) external route
may remain stuck in the routing table after a link flap.
Conditions: Problem observed in Cisco IOS Release 12.4T. Not present in Cisco IOS Release 12.3T.
Workaround: The issue can be resolved by entering the ’clear ip route’ command for the affected
route.

Symptoms: MCP rejecting Start-Control-Connection-Reply (SCCRP) with receive window size
missing.
Conditions: Occurs with peers that use or expect the default handling of RxWindowSize of (4) and
do not include the attribute-value pair (AVP) in the SCCRQ/SCCRP messages.
Workaround: Force peer to send AVP.

Symptoms: PPPoE sessions in relay mode got stuck in attempting state.
Conditions: This symptom is observed on a Cisco router running an internal build of Cisco IOS
Release 12.2(33)SRC.
Workaround: There is no workaround.
• CSCsq34195
Symptoms: The show ip rsvp interface command does not provide reserved bandwidth
information.
Conditions: The symptom is observed on a Cisco 7600 series router that is running Cisco IOS
Release 12.2(33)SRC in an MPLS TE environment.
Workaround: There is no workaround.
• CSCsq36191
Symptoms: When an RP’s CPU memory is almost all consumed (by BGP and/or other processes),
repeated use of the show ip /jointfilesconvert/422273/bgp summary command may cause a router to crash.
Conditions: The symptom is observed when memory is almost all consumed and the command show
ip /jointfilesconvert/422273/bgp summary command is used repeatedly.
Workaround: Upgrade to more memory.

Symptoms: In Ethernet Over MPLS (EoMPLS) environment after fast reroute (FRR) from interface
on SIP600 to interface on SIP400 and re-optimization, traffic is blackholed from CPE device to core.
Conditions: This happen only after FRR from SIP600 module to SIP400 module. FRR between
SIP400 does not experience this problem.
Workaround: There is no workaround.
• CSCsq37520
Symptoms: A crash is seen when a child policy-map is added to a policy-map that is attached to a
large number (1000s) of interfaces.
Conditions: This symptom occurs when any configuration change results in the creation of 1000s of
QoS queues at once.
Workaround: Remove policy-map from all interfaces prior to modification.
