Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S2
• CSCed70979
Symptoms: A router may reload unexpectedly with a bus error and/or display spurious memory
access messages.
Conditions: This symptom is observed when the router is configured for OSPF and is actively
learning OSPF routes dynamically.
Workaround: There is no workaround.
• CSCed75295
Symptoms: FRR LSPs may fail to provide protection with a Next-next-hop (NNHOP) backup
tunnel.
Conditions: This symptom is observed only when a primary LSP reaches beyond a merge point.
Workaround: There is no workaround.
• CSCed82273
Symptoms: IPv6 BGP may not reach the established state.
Conditions: This symptom is observed on a Cisco 12000 series that runs the gsr-p-mz image of
Cisco IOS Release 12.0(26)S2 or Release 12.0(28)S. However, the symptom is not
platform-specific.
Workaround: There is no workaround.
• CSCee10426
Symptoms: A BGP prefix may receive or advertise incorrect label information.
Conditions: This symptom is observed on an MPeBGP session between ASBRs when there is more
than one MPeBGP session configured.
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.
3. The summary LSA IDs for the intra-area routes above, when ORed with the host bits of the
corresponding masks, yield identical LSA IDs.
For example, 10.10.10.128/25 and 10.10.10.0/24 yield identical LSA IDs when the network
address is logically ORed with the host bits; i.e.,
10.10.10.128 | 0.0.0.127 = 10.10.10.255
10.10.10.0 | 0.0.0.255 = 10.10.10.255
Workaround: Perform the clear ip ospf proc command on all ABRs containing the obsolete LSAs.
