Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S3
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.
Miscellaneous
• CSCea65827
Symptoms: A Cisco router performing MPLS label imposition on IPv4 traffic may reload.
Conditions: This symptom is observed when the router attempts to forward traffic to a destination
via a route that is newly learned, when the router forwards traffic via Cisco IOS software (that is,
not via hardware acceleration), and when one of the following conditions is present:
– There are multiple routes to the destination.
– The ip cef accounting non-recursive command is enabled.
– CEF does not install a “cached adjacency” (as seen in the output of the show ip cef prefix
command.)
The symptom affects the following Cisco IOS releases:
– Releases later than Cisco IOS Release 12.0(22)S.
– Cisco IOS Release 12.1 T and a special XT-release that is based on Cisco IOS Release 12.1 T.
– Release earlier than Cisco IOS Release 12.2 S.
– Releases later than Cisco IOS Release 12.2(2)T.
– Cisco IOS Release 12.3.
The symptom does not affect the following Cisco IOS releases:
