Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Workaround: There is no workaround.
Further Problem Description: Whether or not the PE will chose to allocate a local label depends on
the order that the multiple paths for this VPNv4 prefix are learned. The immediate impact is that the
local label allocated takes up memory in the router as the router will populate the LFIB with the
labels.
• CSCsi69342
Symptoms: Whenever Netflow is enabled on interface, all packets start getting process switched and
CPU utilization goes up in IP INPUT process.
Condition: If ip route-cache flow is enabled, it causes packets to be punted to process switching.
Workaround: Remove Netflow commands from the configuration.
• CSCsi76842
Symptoms: Line protocol remains down after the encapsulation on an interface is changed from FR
to PPP/HDLC.
Conditions: Occurs when you set encapsulation FR on an interface. Then change the encapsulation
to PPP/HDLC.
Workaround: Reload the sip-200 module or the SPA.
• CSCsi83287
Symptoms: The following error occurs:
%ALIGN-3-SPURIOUS T/B ipv6fib_gre_ipv6_classified message displayed on console
Conditions: Occurs when an IPv6 tunnel transport endpoint receives fragmented IPv6 packets
Workaround: Use a smaller tunnel MTU on the remote end of the tunnel to prevent fragmentation.
• CSCsi86339
Symptoms: Packets incorrectly go out Traffic Engineering (TE)-Fast Reroute (FRR) back-up tunnel.
Conditions: Occurs when FRR is enabled on a TE tunnel, when 7600-SIP-600 or 7600-ES20 are
used as the MPLS facing Linecard for SVI based EoMPLS or VPLS. PFC-based EoMPLS is not
affected.
Workaround: There is no workaround.
• CSCsi97434
Symptoms: The router will crash when IPSec is established only in the case when both PKI and IKE
AAA accounting are configured.
Conditions: This symptom occurs when PKI is configured, and the DN is used as the ISAKMP
identity. The crash only occurs when the DN is not available, and the server tries to use the DN in
the AAA accounting recording.
Workaround: Do not use this configuration combination (PKI, DN as ISAKMP identity and AAA
accounting).
• CSCsj00870
Symptoms: BADSHARE error messages and traceback are seen during system bootup, swichtover
or online insertion and removal (OIR). Example:
%SYS-DFC6-2-BADSHARE: Bad refcount in datagram_done, ptr=47AA3E2C, count=0 Traceback=

40629A40 406E370C 406E5ADC 40632F74 402AA848
Conditions: Occurs in Cisco Catalyst 6000 series switches running various releases of Cisco IOS
Release 12.2SR.
