OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(29)S
Cisco has made free software available to address this problem.
For more details, please refer to this advisory, available at
http://www.cisco.com/warp/public/707/cisco-sa-20050126-bgp.shtml
• CSCee74110
Symptoms: An RP may crash during the BGP router process after BGP flaps several times.
Conditions: This symptom is observed on a Cisco 12000 series that runs the gsr-p-mz image of a
Cisco IOS interim Release of Release 12.0(29)S. However, this caveat is resolved in
Release 12.0(29)S. This caveat is platform-independent and may occur on another platform that has
an RP and that is configured for BGP.
Workaround: There is no workaround.
• 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.
• CSCee95844
Symptoms: BGP does not efficiently pack updates for VPNv4 prefixes; the prefixes are slowly
advertised because there is only one prefix in each update.
Conditions: This symptom is observed on a Cisco router that runs a Cisco IOS interim release of
Release 12.0(29)S. However, this caveat is resolved in Release 12.0(29)S.
Workaround: There is no workaround.
• CSCef00296
Symptoms: A router crashes when you remove the peer-group members.
Conditions: This symptom is observed on a Cisco router that is configured for BGP.
Workaround: There is no workaround.
• 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
