Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S5
Further Problem Description: The symptom is very unlikely to occur. The symptom does not occur
on a router that has exclusively stub areas and NSSA areas. The symptom may occur when a router
does not have exclusively stub areas and NSSA areas.
• CSCeg30291
Symptoms: BGP fails to send an update or withdraw message to some peers when these peers have
failed to converge properly after an earlier attempt.
Conditions: This symptom is observed on a Cisco router when you enter the clear ip bgp
neighbor-address soft out command while BGP is in the middle of converging. The symptom does
not occur when network traffic load is low and BGP has converged.
Workaround: To clear the error condition, enter the clear ip bgp neighbor-address soft out
command again. Alternately, enter the clear ip bgp neighbor-address command (that is, without the
soft out keyword).
• CSCeg54375
Symptoms: Routing inconsistencies may occur in the RIB: routes may be missing from the RIB but
may be present in the BGP table.
Conditions: This symptom is observed on a Cisco RPM-XF when the toaster processor crashes.
However, the symptom may occur on any platform that has a toaster processor.
Workaround: Enter the clear ip route vrf vrf-name * command.
• CSCeg70726
Symptoms: A router may crash when you enable MVPN by entering the mdt default group-address
command under a VRF.
Conditions: This symptom is observed on a Cisco router that is configured for BGP VPNv4.
Workaround: There is no workaround.
• CSCeh16989
Symptoms: The Multiprotocol BGP (MP-BGP) network entries counter increases above the real
number of reachable networks.
Conditions: This symptom is observed when network activity occurs in a non-converged
environment. The correct number of network entries is restored when there is a period of BGP
stability that last for about 1 minute or more because BGP is able to converge and the scanner has
time to run and collect the old network entries. However, if there is a sustained period of churn and
BGP is only able to converge for a few seconds before new updates arrive, old BGP network entries
are not cleaned up, causing the MP-BGP network entries counter to increase above the real number
of reachable networks.
Workaround: There is no workaround.
• CSCuk54787
Symptoms: When a route map is configured, routes may not be filtered as you would expect them
to be filtered.
Conditions: This symptom is observed on a Cisco router that is configured for BGP and that
functions in an MPLS VPN environment.
Workaround: There is no workaround.
