Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S
Conditions: This symptom is observed on a Cisco router that receives excessive multicast control
traffic.
Workaround: Apply a quality of service (QoS) policy map to limit the rate of the multicast control
traffic that can be received by the router.
• CSCec68467
Symptoms: The memory usage of the Open Shortest Path First version 3 (OSPFv3) process may
increase unexpectedly.
Conditions: This symptom is observed on a Cisco router that runs OSPFv3 when OSPFv3 advertises
routes and when you clear OSPFv3 by entering the clear ipv6 ospf process privileged EXEC
command or when you configure or disable OSPFv3 by entering the ipv6 router ospf or no ipv6
router ospf router configuration command.
Workaround: Shut down the interfaces on which OSPFv3 runs before you make changes to the
OSPFv3 process by entering the commands stated in the Conditions, above.
• CSCec70664
Symptoms: Routes on a provider edge (PE) router may take almost 10 minutes to propagate through
a network because Border Gateway Protocol (BGP) remains in read-only mode for a long period of
time.
Conditions: This symptom is observed on a Cisco router that functions as a PE router and that is a
BGP peer to other PE routers. A list of the affected releases can be found at
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCeb54512. Cisco IOS
software releases that are not listed in the “First Fixed-in Version” field at this location are not
affected.
Workaround: There is no workaround.
• CSCec78690
Symptoms: In rare situations, a User Datagram Protocol (UPD) Gigabit Route Processor (GRP)
leader may bounce and cause problems when trying to converge other Border Gateway Protocol
(BGP) peers.
Conditions: This symptom occurs rarely on a Cisco GRP.
Workaround: Enter the clear ip bgp * EXEC command to clear the symptom.
• CSCec81220
Symptoms: Border Gateway Protocol (BGP) may reload when the outbound policy for a peer
changes.
Conditions: This symptom is observed on all Cisco platforms.
Workaround: There is no workaround.
• CSCec82144
Symptoms: A provider edge (PE) router may reload unexpectedly when you remove a loopback
interface.
Conditions: This symptom is observed on a Cisco router that functions as a PE router and that is
configured for Any Transport over MPLS (AToM) and Fast Reroute (FRR)
Workaround: Do not remove the loopback interface when AToM and FRR are configured.
