Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S
- neighbor Specify a neighbor router
- network Specify a network to announce via BGP
- no Negate a command or set its defaults
- redistribute Redistribute information from another routing protocol
- synchronization Perform IGP synchronization
- table-map Map external entry attributes into routing table
However, the distance bgp external-distance internal-distance local-distance address family or
router configuration command functions fine because the BGP administrative distance for the VPN
in which the command is configured does get changed.
Conditions: The symptom is observed after the BGP IPv4 VPN configuration is saved in NVRAM
and the router is reloaded.
Workaround: Change any of the keywords for the address-family ipv4 vrf vrf-name router
configuration command (see the Symptoms section, above) to a nondefault value.
• CSCec44271
Symptoms: The Multiprotocol BGP (MBGP) feature does not function when a router is configured
as a Border Gateway Protocol (BGP) route reflector.
Conditions: This symptom is observed when a BGP peer group has been enabled and then the MBGP
feature is added.
Workaround: Reset the BGP peer group by removing the peer group configuration and adding it
back.
• CSCec45770
Symptoms: A memory leak may occur on a router that runs IPv6 Open Shortest Path First version 3
(OSPFv3), and the following error message that is related to chunks may be generated:
SYS-2-CHUNKSIBLINGS: Attempted to destroy chunk with siblings Tracebacks may also be
generated.
Conditions: This symptom is observed when a configuration change occurs in which prefixes are
added or deleted or when the router reloads and the same prefix is advertised with a different Link
State ID (LSID).
Workaround: There is no workaround.
• CSCec48816
Symptoms: When you remove network commands from a router, the router may reload
unexpectedly with the following stacktrace:
0x40AE7744:ospf_clean_if(0x40ae76c8)+0x7c
0x40AE46FC:ospf_attach_interface(0x40ae4524)+0x1d8
0x40AE20CC:ospf_parse_range(0x40ae1bb8)+0x514
0x40AE1A7C:ospf_network_cmd_apply(0x40ae1a58)+0x24
0x40AE1AC8:ospf_process_network_cmdQ(0x40ae1a88)+0x40
0x40ADCC3C:ospf_router(0x40adca1c)+0x220
Conditions: This symptom is observed on a Cisco router that has the router ospf global
configuration command enabled and you remove network commands.
Workaround: There is no workaround.
• CSCec51206
Symptoms: A memory allocation failure (MALLOCFAIL) from the I/O memory pool may occur.
