Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(29)S
• CSCin65241
Symptoms: ISIS redistribute commands are not synced to the standby RP. The routes dependent on
these commands will fail after switchover.
Conditions: This symptom is observed on a Cisco 7500 series router.
Workaround: There is no workaround.
ISO CLNS
• CSCee54672
Symptoms: The redistribution of routes from L1 into L2 or/and from L2 into L1 may not occur
properly, and a learned IS-IS prefix may be missing.
Conditions: This symptom is observed under the following conditions:
– There are multiple paths to reach the same prefixes.
– One source LSP removes a prefix and another LSP adds the same prefix, while both paths
between the prefix and the LSPs are of equal cost.
Workaround: Enter the clear isis * or the clear ip route * command to restore the prefix. However,
doing so clears all the routes and recalculates them again, which is a disruptive action.
Miscellaneous
• CSCdx59158
Symptoms: An active Route Processor (RP) sets the link correctly to the “down” state, but the
standby RP fails to set the link correctly.
Conditions: This symptom is observed on a Cisco 10000 series when the far end causes the link state
to flap from “up” to “down.” However, the symptom is not platform-specific and may also occur on
other platforms that have dual RPs.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command.
• CSCdx87477
Symptoms: The adjacency table does not display information that is related to the virtual access
interface of a network access server (NAS) when the show adjacency detail EXEC command is
entered.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.2(13)T or
Release 12.2(14)S but may also occur in other releases.
Workaround: There is no workaround.
• CSCdz56772
Symptoms: A router that is configured for Cisco Express Forwarding version 6 (CEFv6) may reload
when the supported state of an interface changes and when the associated prefix is deleted.
For example, a router may reload when a tunnel interface changes from a CEFv6 unsupported mode
(for example, generic route encapsulation [GRE] IP version 6 [IPv6]) to a supported mode (for
example, IPv6 IP) and you remove the associated IPv6 address by entering the no ipv6 address
ipv6-address interface configuration command or by shutting down the tunnel interface.
Conditions: This symptom is observed on all platforms that run Cisco IOS Release 12.2 S or
Release 12.2(13)T but may also occur in other releases.
