Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S1
Workaround: Configure the neighbors by grouping into sets or peer-groups, in which a few of the
neighbors in each set share similar outbound policy. Each set will fall into a separate update group
or peergroup.
• CSCee83549
Symptoms: When multipath is configured, one of the paths may have an inconsistent (old) label,
causing only one path to be operational.
Conditions: This symptom is observed when BGP does not update the outlabel information in the
TFIB and for CEF.
Workaround: Clear or readvertise the route that is inoperational.
• CSCee89438
Symptoms: An MSDP enabled RP does not build an (S,G) state from its SA cache when it should
do so. Depending on the topology and if an SPT threshold is configured as infinite, this situation
may result in a multicast forwarding interruption of up to 2 minutes.
Conditions: This symptom is observed when the RP for a group fails and an incoming (*,G) join
message is received.
MSDP should create an (S,G) state from its SA cache. However, this is done before the (*,G) olist
is populated; because of the (*,G) NULL olist, MSDP does not install an (S,G) state.
Workaround: Enter the clear ip mroute * command on all first-hop routers to the source to enable
the FHR to register immediately when the next packet creates an (S,G) state.
• CSCef00535
Symptoms: An OSPF router may reload unexpectedly.
Conditions: This symptom is observed after a neighbor has performed a switchover.
Workaround: Disable LLS under the OSPF process on the router by entering the no capability LLS
command or disable OSPF NSF under the OSPF process on the neighbor by entering the no nsf
command.
• CSCef17311
Symptoms: An %ALIGN-3-SPURIOUS error message and a traceback may be generated when you
configure BGP and MPLS VPN.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS interim
Release 12.3(9.10)T but may also occur in other releases such as Release 12.0 S and Release 12.2 S.
Workaround: There is no workaround
• CSCin65241
Symptoms: ISIS redistribute commands are not synced to the standby RP. The routes dependent on
these commands will fail after switchover.
Conditions: This symptom is observed on a Cisco 7500 series router.
Workaround: There is no workaround.
ISO CLNS
• CSCee54672
Symptoms: The redistribution of routes from L1 into L2 or/and from L2 into L1 may not occur
properly, and a learned IS-IS prefix may be missing.
