Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S
Conditions: This symptom is observed rarely when all of the following conditions are present:
There is a very brief (shorter than 500 ms) interface flap on a point-to-point interface such as a
POS interface.
The flap is not noticed by the neighbor, so the neighbors interface remains up.
The OSPF adjacency goes down and comes back up very quickly (the total time is shorter than
500 ms).
OSPF runs an SPF during this period and, based on the transient adjacency information,
removes routes via this adjacency.
The OSPF LSA generation is delayed because of LSA throttling. When the LSA throttle timer
expires and the LSA is built, the LSA appears unchanged.
Workaround: Increase the carrier-delay time for the interface to about 1 second or longer.
Alternate Workaround: Use an LSA build time shorter than the time that it takes for an adjacency to
come up completely.

Symptoms: When an inter-area, external, or Not-So-Stubby Area (NSSA) route is learned via a link
state update that follows the initial database synchronization, the route may not be added to the
routing table by a partial shortest path first (SPF) computation even though the LSA is installed in
the link state database. A subsequent full SPF computation causes the route to be added.
Conditions: This symptom is observed on a Cisco router and is most likely to occur when a large
number of type 3, type 5, or type 7 LSAs are advertised and withdrawn.
Workaround: Trigger an action that causes a full SPF computation.
CSCsc36517
Symptoms: A router reloads unexpectedly when a continue statement is used in an outbound route
map.
Conditions: This symptom is observed on a Cisco router that is configured for BGP.
Workaround: There is no workaround.
CSCsc49741
Symptoms: A router may crash when OSPFv3 is enabled.
Conditions: This symptom is observed on a Cisco router that runs a Cisco IOS software image that
integrates the fix for caveat CSCei47926. A list of the affected releases can be found at
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCei47926. 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.
CSCsc59089
Symptoms: BGP does not advertise all routes to a peer that sends a route-refresh request.
Conditions: This symptom is observed under the following conditions:
The router is in the process of converging all of its peers and has updates ready in the output
queue for the peer.
The peer sends a route-refresh request to the router. This may occur when the clear ip /jointfilesconvert/415844/bgp *
soft in command is entered on the peer or when a VRF is added to the peer.
The router processes the route-refresh request from the peer while the router still has updates in
the output queue for the peer.
