Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8

OL-10394-05 Rev. R0

• CSCsu04360

Symptoms: Acct-Time-Delay and Tunnel-Link-Stop records are missing from L2TP network server

(LNS).

Conditions: Occurs when using radius server for authentication.

Workaround: There is no workaround.

• CSCsu04473

Symptoms: Upon the first SSO switchover triggered with the redundancy force-switchover

command, the traffic stops on the ATM N-to-1 VCC pseudowires configured with cell-packing in

the direction from the MWR towards the 7600 SPA-4XOC3-ATM interface. Traffic recovers

normally in the other direction.

Conditions: Occurs on a Cisco 7600 S-series equipped with dual SUP720-3BXL. The problem is

seen only when cell-packing is enabled on the N-to-1 VCC pseudowires and when APS (MR-APS)

is configured on the ATM OC3 interface of the Cisco 7600 SPA-4XOC3-ATM.

Workaround: Disable cell-packing on the ATM N-to-1 VCC pseudowires or alternatively disable

APS on the SPA-4XOC3-ATM interface.

• CSCsu05525

Symptoms: After removing the "default-originate" configuration, the default-route is not

withdrawn.

Conditions: Occurred on a router running Cisco IOS Release 12.2SR.

Workaround: Clear the session to remove the configuration.

• CSCsu08935

Symptoms: BGP as-override does not work properly on a PE to overwrite the AS in the AS4_PATH.

Conditions: When a 4 byte CE is peered to a 2 byte capable PE using AS 23456 and the command

as-override is configured on the neighbor, the PE router does not override the AS in the AS4_PATH

with its own AS number, mapped to 4 bytes.

Workaround: Use "allowas-in" on the CE.

• CSCsu10229

Symptoms: cdpCacheAddress(OID:1.3.6.1.4.1.9.9.23.1.2.1.1.4) MIB is not showing

GLOBAL_UNICAST address.

Conditions: Occurs on a Cisco 7200 router running Cisco IOS Release 12.4(15)T7.

Workaround: There is no workaround.

• CSCsu12040

Symptoms: BGP neighbors that are configured with as-override and send-label (CsC) together may

not work after an interface flap or service reset.

Conditions:

neighbor xxx as-override neighbor xxx send-label

Workaround: Enter the "clear ip /jointfilesconvert/422273/bgp * soft in" command.

Further Problem Description: Peers (neighbors) with a CsC (IPv4+label) BGP configuration with

the as-override option should be separated into different dynamic update groups during the BGP

update generation process. After the CSCef70161 fix in Cisco IOS Release 12.0(32)SY4, this is no

longer the case; this CSCsu12040 fix enhances the CSCef70161 fix to handle the CsC (IPv4+label)

case separately.
