Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: The crash is caused by a ping across an ISATAP tunnel. The symptom is observed only
in Cisco IOS Release 12.4(15)T7 on the Cisco 7200 (it is not known to affect other platforms), since
the crash is dependent on the Cisco IOS memory map (which varies with each image).
Workaround: There is no workaround.

Symptoms: The EIGRP IPv6 process may incorrectly select a router-ID from the 127.0.0.0 address
range.
Symptoms: The same router-ID may be selected on two separate Cisco routers configured for
EIGRP IPv6. External prefixes advertised by one of the EIGRPv6 routers will be ignored by the
receiving EIGRPv6 router due to the fact the routerID contained in the external data portion of the
prefix matches the receiving routerID; a loop prevention method.
Workaround:Manually configure a router-ID under the EIGRP IPv6 process with
router-id<address> command.

Symptoms: Line card MAC notification test fails when redundancy mode is changed from RPR to
SSO or SSO to RPR. SIP-400 Bus Connectivity Test failed when the following commands are
issued:

Conditions: The issue observed in the Fabric Hot Sync-enabled Sup720 and RSP720 routers Cisco
IOS Release 12.2(33)SRC. In the problem state, Super Santa Ana (SSA) channels are out of sync.

CWAN module console.
Workaround: There is no workaround.
