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
CSCei65865
Symptoms: When an RSVP application (for example, the MPLS TE feature) sends an updated Path
message to reflect a modification in its QoS request, the updated Path message may not be forwarded
by a downstream RSVP-aware router.
Conditions: This symptom is observed when the downstream RSVP-aware router has two RSVP
features configured: local policy and refresh reduction. The commands to configure these features
are the ip rsvp policy local command and the ip rsvp signalling refresh reduction command,
respectively.
When an RSVP reservation is established with a Path/Resv message handshake and the sender
application subsequently transmits an updated Path message that the downstream router applies to
an RSVP local policy, the router does not forward the modified Path message. This situation
prevents the application from receiving the corresponding Resv message, and may cause the
application to fail.
Workaround: If this is an option, unconfigure the local RSVP policy or refresh the reduction and
then restart the RSVP application. If this is not an option, there is no workaround.

Symptoms: OSPFv3 may write zeros into single words of memory in the heap. Depending on what
(if anything) is allocated at the address that is being cleared, the router may reload or fail in some
other way.
Conditions: This symptom is observed only when an OSPFv3 process or area is unconfigured or
when you enter the clear ipv6 ospf process command and when both of the following conditions
are present:
The area that is removed or the process that is cleared contains one or more non-self-originated
type-4 LSAs.
The router does not have an intra-area path to an ASBR that is described by the type-4 LSA.
Workaround: There is no workaround.
CSCei77227
Symptoms: A Cisco router that functions in a multicast VPN environment may crash.
Conditions: This symptom is observed when you check the unicast connectivity and then
unconfigure a VRF instance.
Workaround: There is no workaround.
CSCei83265
Symptoms: MVPN traffic is limited to about 9 Mpps and the CPU usage on the egress line card is
100 percent.
Conditions: This symptom is observed on a Cisco router that functions as a PE router when MVPN
performs decapsulation in the slow path instead of the fast path.
Workaround: There is no workaround.
CSCei86031
Symptoms: When the distribute-list route-map map-tag command is used under the OSPF router
mode and when the route map is modified, OSPF does not update the routing table based on the
changes in the route map.
Conditions: This symptom is observed when a route map that is referenced in the distribute-list
route-map map-tag command is modified.
Workaround: Enter the clear ip ospf process id command or the clear ip route * command.
