Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S1
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0S,
Release 12.2S, or Release 12.3T.
Workaround: There is no workaround.
• CSCee11274
Symptoms: BGP may fail to reestablish a session when you remove a line card, PA, VIP, or module
and replace it with a card of a different type. For example, the problem occurs when you remove a
1-port GE line card and replace it with a 3-port GE line card. However, if you replace the 1-port GE
line card with another 1-port GE line card (or you just plug the same 1-port GE line card back in the
chassis), the problem does not occur.
Conditions: This symptom is observed when the router one side of the BGP session is configured
with the neighbor ip-address transport connection-mode active command and when a line card,
PA, VIP, or module is changed on the router at the other side of the BGP session. Furthermore, the
router at the other side of the BGP session is configured with the neighbor ip-address
update-source interface command, and the interface argument refers to the interface on the line
card, PA, VIP, or module that is changed.
Workaround: Disable and reenter the neighbor ip-address update-source command.
• CSCee12740
Symptoms: Traffic through some MPLS TE tunnels may not resume after a forced switch-over has
occurred on a router.
Conditions: This symptom is observed on a router configured with Multiprotocol Label Switching
(MPLS) traffic engineering (TE) tunnels and OSPF.
Workaround: Perform clear ip ospf process on the router.
• CSCee24899
Symptoms: A router that is configured for multicast routing may reload due to a bus error.
Conditions: This symptom is observed on a Cisco router that runs a Cisco IOS software release that
contains the fix for CSCec80252. A list of the affected releases can be found at
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCec80252. Cisco IOS
software releases that are not listed in the “First Fixed-in Version” field at this location are not
affected.
Workaround: There is no workaround.
• CSCee35125
Symptoms: A Cisco router may crash when you enter the clear ip route * command.
Conditions: This symptom is observed when the routing table has a default route.
Workaround: There is no workaround.
• CSCee36622
Symptoms: ABRs may continue to generate summary LSA(s) for obsolete non-backbone intra-area
route(s).
Conditions: This symptom occurs under the following conditions:
1. The ABR (call ABR X) has at least one non-backbone area (call area X) in common with one
or more additional ABRs.
2. The ABRs are generating summary LSAs, on behalf of the Area X’s two or more intra-area
routes, into the backbone area and other areas. The two intra-area routes must be advertised as
stub links from two different routers; i.e., one from ABR X, and the other from another router
belonging to Area X.
