Cross-Platform Release Notes for Cisco IOS Release 12.0S

OL-1617-14 Rev. Q0

Caveats

Resolved Caveats—Cisco IOS Release 12.0(30)S5

Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS

Release 12.0(30)S1 when a Multilink Frame Relay (MFR) interface is shut down in the

configuration of the connect command, causing proper provisioning to fail, unprovisioning to occur,

and the error message to be generated.

Possible Workaround: Enter the no shutdown interface configuration command on the MFR

interface.

The Cisco IOS Stack Group Bidding Protocol (SGBP) feature in certain versions of Cisco IOS

software is vulnerable to a remotely-exploitable denial of service condition. Devices that do not

support or have not enabled the SGBP protocol are not affected by this vulnerability.

Cisco has made free software available to address this vulnerability for affected customers. There

are workarounds available to mitigate the effects of the vulnerability.

Cisco has published a Security Advisory on this issue; it is available at

http://www.cisco.com/warp/public/707/cisco-sa-20060118-sgbp.shtml

• CSCsb12969

Symptoms: All VIPs or FlexWAN modules reload unexpectedly on a platform that is configured for

Modular QoS CLI (MQC).

Conditions: This symptom is observed on a Cisco 7500 series (with VIPs) and a Cisco 7600 series

and Cisco Catalyst 6500 series (both with FlexWANs) when the following steps occur while the

physical interface is in the UP state:

1. An input policy and output policy map are already attached to an ATM or Frame Relay PVC.

When you attach the same policy map to the main interface, an error message is generated and

the configuration is rejected.

2. You remove the policy map from the PVC and attach the same policy map to the main interface.

3. You remove the policy map from the main interface.

At this point, all VIPS or FlexWAN modules reload, even though no traffic is being processed during

the above-mentioned steps.

Workaround: There is no workaround.

• CSCsb28139

Symptoms: An LDP/BGP adjacency is not formed, and a ping does not go through.

Conditions: This symptom is observed on a Cisco 12000 series that functions in a scaled VPN

environment when an Engine 6 line card faces the core of the MPLS network.

Workaround: Enter the clear ip route * command.

• CSCsb39165

Symptoms: A Cisco router may report high CPU usage and memory depletion under a specific

MPLS VPN configuration with static routes.

Conditions: This symptom is observed when equal cost static routes to a subnet point to a next hop

address and there is a summary route that covers one of the next hops pointing to Null0.

If the directly connected route to the next hop is terminated because the interface goes down, the

original route recurses to Null0 while the route recursing through the interface that is still up remains

in the routing table. The end result is that the route now points to both Null0 and to a valid interface

that is up, causing an MPLS recursion problem that results in high CPU usage and memory

depletion.

The following is an example configuration:
