Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Workaround: There is no workaround.
• CSCsm53196
Symptoms: Crash occurs at “ip_route_delete_common”.
Conditions: Occurs under the following scenario:
1)A multicast BGP route exists.
2)A unicast BGP route exists for the same prefix.
3)Another route covered by the same majornet as the BGP route exists.
4)There are both iBGP and eBGP sources for the BGP prefix.
5)Redistribution of BGP routes into an IGP must be configured.
Topology change in network causes mBGP to switch from using the iBGP sourced route to the eBGP
sourced route will cause the crash.
Workaround: If there are not both iBGP and eBGP sources for the same route the problem will not
occur. If redistribution of BGP Into an IGP is not configured the problem will not occur.
• CSCsm55817
Symptoms: When configuring ATM PVCs, under the PVC syntax you can provide a handle to
describe the PVC. If this handle starts with “00” (zero zero) then the command will fail.
Conditions: The symptom is observed when configuring ATM PVCs and where the PVC handle
starts with “00”.
Workaround: Do not use handles that start with “00”.
• CSCsm64307
Symptoms: When PPP sessions are terminated, the standby NPE may crash. This is true for both
PPP sessions that are terminated naturally (from the customer end), and those that are terminated
prematurely (at the provider end due to a command such as clear pppoe sessions all).
Conditions: At present the conditions are unknown. It only appears to impact 12.2(31)SB10 and
related releases.
Workaround: There is no workaround.
• CSCsm71537
Symptoms: The router crashes when Independent Optimized Edge Routing (OER) is configured.
Conditions: Occurs when OER is configured.
Workaround: There is no workaround.
• CSCsm86832
Symptoms: The line protocol of the serial interface keeps flapping.
Conditions: This symptom is observed after the Atlas BERT pattern is run on a fractional T1 (1 or
2 timeslots).
Workaround: Add/Remove the T1.
• CSCso00864
Symptoms: System running in crypto engine mode vrf with SVI interfaces that have crypto map
attached and is in SSO redundancy mode may experience crash of the standby supervisor when the
interface referenced by crypto map local address is modified.
Conditions: The system is in SSO redundancy mode, has SVI interfaces with crypto map
configuration and running in “VRF mode”.
