Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S
Workaround: There is no workaround. Note that the old LSP times out after five minutes.
• CSCea66336
Symptoms: A Cisco router may be unable to set up a Frame Relay or an ATM permanent virtual
connection (PVC). When you enter the debug ip rsvp traffic-control EXEC command, the
following message is displayed:
RSVP-TC: Unable to determine resource provider for tcsb
Conditions: This symptom is observed on a Cisco router that is running Cisco IOS
Release 12.2(15)T.
Workaround: There is no workaround.
• CSCea81029
Symptoms: A Cisco router may reload unexpectedly when you enter a show command that is related
to IP multicast.
Conditions: This symptom is observed on a Cisco router that has remained at the “more” prompt for
a long period of time.
Workaround: There is no workaround.
• CSCeb27742
Symptoms: A Cisco router with a Border Gateway Protocol (BGP) system may lose the address
family’s use of aggregate routes after the router reloads. The aggregate routes are moved from the
VPN routing/forwarding (VRF) address family and appear under the global IP version 4 (IPv4)
address family. When the router reloads, the console displays the following error messages:
exit-address-family ^
% Invalid input detected at “^” marker.
exit-address-family ^
% Invalid input detected at “^” marker.
exit-address-family ^
% Invalid input detected at “^” marker.
The above symptom is only one of the possible symptoms. Support for the auto-summary router
configuration command and the default-information originate router configuration command has
been removed from some of the address families as a result of the caveat CSCdx14351 without
providing support to accept these commands silently when being booted with a configuration from
a prior Cisco IOS release. The presence of the unsupported commands in address families like
Virtual Private Network version 4 (VPNv4) and IPv4 Multicast (MCAST) causes the command-line
interface (CLI) to go out of the address family submode and apply these commands to the v4 address
family, which results in unpredictable behavior.
Conditions: This symptom is observed on all Cisco platforms that are running Cisco IOS
Release 12.2(16.4)T or Release 12.3 T. The symptom is not observed in Cisco IOS Release 12.3.
Workaround: Reenter the configuration that was present before the router reloaded.
• CSCeb42893
Symptoms: A Cisco 7200 series may select the best path inconsistently.
Conditions: This symptom is observed on a Cisco 7200 that runs Cisco IOS Release 12.0(26)S when
the bgp deterministic med router configuration command, the bgp always-compare-med router
configuration command, or both commands are configured to determine the best path.
Workaround: Use other commands or methods to determine the best path.
