Caveats
Resolved Caveats—Cisco IOS Release 12.0(33)S2
• CSCsk89546
Symptoms: OSPF routes are not populated in the Routing Information Base (RIB) with the next hop
as traffic engineering (TE) tunnels.
Conditions: Occurs when multiple TE tunnels are configured and the tunnels come up or are shut/no
shut simultaneously.
Workaround: Shut/no shut tunnels one at a time.
• CSCsl05174
Symptoms:
–
Issue 1: A non-deleted PPP configuration inside the interface reappears when the interface is
created again.
–
Issue 2: Some multilink configuration is not being synced to the standby (hold-queue).
Conditions: This symptom is observed when running RPR+.
Workaround: Reapply the original configuration.
Further Problem Description: Deletion of a multilink interface and subsequent creation using the
same name may cause portions of the original configuration to return even if not explicitly
configured. The hold-queue command is not being synchronized to the standby RP.
• CSCsl51616
Symptoms: The v6-vrf-lite configuration does not synch properly with the standby; hence
100 percent of the traffic is lost after an SSO switchover.
Conditions: The conditions under which this symptom is observed are unknown.
Workaround: There is no workaround.
• CSCsl61164
Symptoms: Router may crash @ipflow_fill_data_in_flowset when changing flow version.
Conditions: Occurs when NetFlow is running with data export occurring while manually changing
the flow-export version configuration from version 9 to version 5 and back to version 9 again.
Workaround: Do not change the NetFlow flow version while the router is exporting data and routing
traffic.
• CSCsl68227
Symptoms: An E3 linecard may drop packets larger than a certain size because of a buffer carving
problem when the mtu command is used for multilink interfaces.
Conditions: This symptom is observed with images based on Cisco IOS Release 12.0(32)S10.
Workaround: Changing the MTU or reloading the linecard may clear the problem.
• CSCsl83415
Symptoms: After executing the following CLI commands (steps mentioned alphabetically) via a
script (not reproducible manually), the router sometimes crashes:
Test10:
a. clear ip /jointfilesconvert/415844/bgp 10.0.101.46 ipv4 multicast out
b. clear ip /jointfilesconvert/415844/bgp 10.0.101.47 ipv4 multicast out
