Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S4
Workaround: Disable and re-enter the ip multicast boundary command.
Alternate Workaround: Enter the clear ip mroute * command.
• CSCsb69773
Symptoms: The router may crash.
Conditions: This symptom has been observed following a switchover from the primary RP to the
secondary RP.
Workaround: There is no workaround.
• CSCsc00378
Symptoms: Changes in an export map are not picked up by the BGP Scanner.
Conditions: This symptom is observed on a Cisco router that functions as a PE router when you
apply an export map to a VRF and when the interface that connects the PE router to a CE router is
configured for OSPF.
Workaround: Enter the clear ip ospf process command to enable the BGP Scanner to pick up the
changes in the export map.
• CSCsc74229
Symptoms: A router may delete the VPNv4 prefixes from the BGP table, even though the counters
in the output of the show ip /jointfilesconvert/415844/bgp command may indicate that the VPNv4 prefixes are present in the
BGP table. This situation may cause loss of VPN connectivity.
Conditions: This symptom is observed on a Cisco router that is configured for MPLS VPN and that
functions as a PE router.
Workaround: There is no workaround. When the symptom occurs, enter the clear ip /jointfilesconvert/415844/bgp * command
to restore proper operation of the router.
• CSCsc76327
Symptoms: When a VRF route is redistributed into the MP-BGP cloud, a routing loop may occur
for the prefix (that represents the VRF route) between the EIGRP cloud and the MP-BGP cloud.
Conditions: This symptom is observed on a Cisco router that functions as a PE router when the
following conditions are present:
–
The router has EIGRP configured on the link to a CE router.
–
The router has a static VRF route that is redistributed into the configuration that is defined by
the address-family vrf vrf-name command and that is part of the BGP routing process.
Workaround: There is no workaround. Applying a route map with a pre-bestpath option does not
resolve the loop.
• CSCsd03383
Symptoms: A route is not installed through an MPLS TE tunnel even though the tunnel mpls
traffic-eng autoroute announce command is enabled.
Conditions: This symptom is observed on a Cisco router that also has the mpls traffic-eng
multicast-intact command enabled.
Workaround: There is no workaround.
• CSCsd04704
Symptoms: A router crashes when you enter the show ip /jointfilesconvert/415844/bgp pending-prefixes command.
Conditions: This symptom is observed on a Cisco router that runs an interim release for Cisco IOS
Release 12.0(32)S and that is configured for BGP
