Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S
Conditions: This symptom is observed when IPv6 BGP is configured and when a route changes from
iBGP to eBGP or the other way around.
Workaround: Repopulate CEF with the correct forwarding information by entering the clear ipv6
route ipv6-address command.
CSCef62335
Symptoms: A “VCID already in use” error message may be generated when you attempt to create
an L2TPv3 session.
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS Release 12.2S
after you first have configured and removed a pseudo-wire configuration and then have removed the
xconnect configuration from the PVC. The symptom may also occur in other releases.
Workaround: There is no workaround.
CSCef63272
Symptoms: A recursive static default route may not have an outgoing MPLS label, causing all
packets to be dropped.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.3(9) but
may also occur in other releases.
Workaround: Add a nonrecursive static route to the BGP next-hop.
CSCef66517
Symptoms: When you send larger than fragment-sized packets from an interface that has a traffic
shaping class configured, the packets get stuck when the queue size increases to the queue limit, and
subsequent traffic is tail-dropped.
Conditions: This symptom is observed when a policy is attached to a multilink interface that has a
traffic shaping class configured and when the interface is configured for fragmentation.
Workaround: There is no workaround.
CSCef67267
Symptoms: The Fast ReRoute database shows all prefixes in the active state.
Conditions: This symptom is observed on a Cisco router after a connected point of local repair
(PLR) has rebooted.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the interface on which the primary tunnel is configured. Doing
so restores the prefixes to the ready state.
CSCef67840
Symptoms: When the CEF table consistency checker is configured to perform a passive scan check
of tables of the line cards, the CEF table consistency checker may report false inconsistencies, which
you can view in the output of the show ip cef ip-address command. The false inconsistencies may
occur because of a race condition.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(27)S1.
If an inconsistency is reported for a recursive loadbalanced route for which the output interfaces for
the next-hop IP address differ between the RP and line card, you can ignore this inconsistency
because this information is not used during the forwarding process.
Workaround: Disable the CEF table consistency checker so that no passive scan check is performed
of tables of the line cards.
