Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S11
Conditions: This symptom is observed on a Cisco router after a route flap in the network causes the
traditional 0.0.0.0/0 default route to be relearned by a router. In turn, the router advertises this
default route to its peers, overriding the previously sent default-originate route. The result is that the
BGP peer router learns the default route that has been propagated through the network, rather than
the default route that has been created using the neighbor default-originate command on the
adjacent router.
Workaround: Manually clear the BGP neighbor to enable the peer router to correctly relearn the
correct default route (the one generated by the neighbor default-originate command).
CSCsf28907
Symptoms: Embedded RP does not work in Cisco IOS Release 12.0(32)S or later releases.
Conditions: This symptom is observed on Cisco 12000 and Cisco 10720 routers with IPv6 multicast
routing in Cisco IOS Release 12.0(32)S or later releases.
Workaround: Enter the no ipv6 pim rp embedded command and then the ipv6 pim rp embedded
command in the global configuration mode.
CSCsf29803
Symptoms: An engine 3 linecard in an mVPN PE router with multicast egress QoS configured may
report the following error message and may also reload after this message:
SLOT 10:Sep 5 15:12:43.879 UTC: %EE48-3-CONGA_MCAST: Table indices not linked:
(tbl1=262129, tbl2=262136, prev=0, oiq_id=0, oi=0, oq=0)
Conditions: This symptom is observed when an engine 3 linecard in an mVPN PE router has both
core interfaces and VRF interfaces configured and an output service policy applied to one or more
of these interfaces.
Workaround: Limit engine 3 linecards with service policies to either core interfaces or VRF
interfaces, and do not combine both interface types on a single linecard. Note that Cisco
recommends that core and VRF interfaces not be configured on the same linecard anyway because
any multicast packet that needs to egress on both interfaces will be software-forwarded and not
hardware-forwarded. Alternatively, replace the engine 3 linecard with an engine 5 linecard.
CSCsg25995
Symptoms: Networks do not show up in the BGP table for multicast address family, as can be seen
in the output of the show ip m/jointfilesconvert/415844/bgp command.
Conditions: This symptom is observed when BGP is used for multicast address family; it does not
affect unicast address family.
Workaround: Use the clear ip /jointfilesconvert/415844/bgp neighbor-address command.
CSCsg32689
Symptoms: A crash or traceback may occur when the route-map option for fall-over is configured
for a BGP peer-session template or peer group.
Conditions: This symptom occurs when the fall-over [route-map map-name] command is
configured under the router /jointfilesconvert/415844/bgp autonomous-system-number command.
Workaround: There is no workaround. Avoid using the route-map option.
CSCsg35077
Symptoms: A device that is running Cisco IOS software may crash during processing of an Internet
Key Exchange (IKE) message.
Conditions: The device must have a valid and complete configuration for IPsec. IPsec VPN features
in Cisco IOS software that use IKE include Site-to- Site VPN tunnels, EzVPN (server and remote),
DMVPN, IPsec over GRE, and GET VPN.
