Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S3
–
P1 connects also to another P router (P2) that connects to yet another P router (P3), that, in turn,
connects to P10, forming a second backup NHOP FRR protection tunnel via an LSP path.
When the link between P1 and P10 breaks at P1, the secondary backup tunnel does not come up
immediately, causing packet loss of around 200 ms (about 90 percentile) when the link goes down
and 5 seconds when the link finally comes up again.
Workaround: Enter the mpls traffic-eng topology holddown sigerr 0command on the affected
tunnel head-end (P10) to prevent the backup LSP from being hold down.
Further Problem Description: This symptom is only observed with 1-port 10-Gigabit Ethernet
Engine 5 SPAs.

Symptoms: Auto-RP messages from a CE router are lost.
Conditions: This symptom is observed when you enter the clear ip mroute * on a connected PE
router. The messages do not recover by themselves.
Workaround: To restart Auto-RP messages, enter the clear ip mds linecard command.
Alternate Workaround: To restart Auto-RP messages, debug the VRF Auto-RP by entering the
debug ip pim vrf vrf-name auto-rp.

Symptoms: An interface of an Engine 6 line card is no longer shut down after an RP switchover
occurs.
Conditions: This symptom is observed on a Cisco 12000 series when the following events occur:
1. The interface of the Engine 6 line card is configured with the no shutdown interface
configuration command in the startup configuration.
2. The router is reloaded and you verify that the interface comes up.
3. You enter the shutdown interface configuration command on the interface.
4. You enter the write memory command.
5. You enter the redundancy force command.
After the new RP comes up, the interface appears no longer shut down and the interface comes up
again.
Workaround: After you have entered the shutdown interface configuration command on the
interface followed by the write memory command, reload the router.

Symptoms: A service policy on an Engine 4 + or Engine 6 line card is incorrectly rejected with the
following error message:
%E4P and E6 LC requires to configure POLICE and SET %command in every class if either
of these two commands %is configured in class-default class
This situation occurs when a set command is used in all classes.
Conditions: This symptom is observed on a Cisco 12410 that runs Cisco IOS Release 12.0(28)S3,
that is configured with dual Performance Route Processors (PRP-1s) that operate in SSO mode, and
that has multiple E4+ and/or Engine 6 line cards.
Workaround: There is no workaround.
