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

OL-10394-05 Rev. R0

• CSCsm04442

Symptoms: Delete an interface which has ip summary-address rip configured. The router crashes.

Conditions: In the scenario where different summary addresses are configured for different

interfaces, if we delete an interface that has a summary-address configuration which is the last one

for that summary-address that it leads to.

Workaround: Remove the ip summary-address rip configuration from an interface which is going

to be deleted.

• CSCsm05646

Symptoms: After an SSO switchover, an Interface VLAN (SVI) may remain in a DOWN state,

although the VPLS VC state is UP. Bridged traffic is not affected, although L3 related traffic will be

affected in the case of Routed EoMPLS/VPLS.

Conditions: The symptom is observed on a Cisco 7600 series router that is configured with H-VPLS

with MPLS access (Hierarchical VPLS with MPLS access), Routed EoMPLS or Routed VPLS, and

operating in SSO Redundancy Mode, without a switchport or Multipoint Bridging EVC in the

VLAN.

Workaround: The workaround is to add a switchport allowing the VLAN. This should keep the

Interface VLAN in an UP state across the SSO switchover. Alternatively, a shutdown followed by a

no shutdown in the Interface VLAN under the conditions above recovers the failure. This

shutdown/no shutdown can be automated by using Embedded Event Manager, monitoring the SSO

switchover and automatically issuing the shutdown/no shutdown on the Interface VLAN in question.

• CSCsm06057

Symptoms: c7600-SIP-400 stops forwarding traffic after RPR+ switchover

Conditions: If the redundancy mode is RPR+ and after the switchover happens, traffic through the

c7600-SIP-400 stops.

Workaround: Reset the linecard using the hw-module module <slot> reset.

• CSCsm06740

Symptoms: A memory leak occurs when CLI commands are issued when AAA command

accounting is configured.

Conditions: This issue occurs only when AAA accounting is configured. For example:

aaa accounting update newinfo

aaa accounting exec default start-stop group GROUPINFO

aaa accounting commands 15 default start-stop group GROUPINFO

Workaround: Remove AAA accounting configuration.

• CSCsm06762

Symptoms: When displaying routes in a routing table, the last update time may sometimes be shown

as "7w0d" when the route has recently been updated. For example:

router#show ip route 192.168.116.152

Routing entry for 192.168.116.152/30 Known via "rip", distance 120, metric 1

Redistributing via /jointfilesconvert/422273/bgp 6747, rip Advertised by /jointfilesconvert/422273/bgp 6747 Last update from

192.168.117.154 on GigabitEthernet2/5.2583, 7w0d ago Routing Descriptor Blocks: *

192.168.117.154, from 192.168.117.154, 7w0d ago, via GigabitEthernet2/5.2583 Route

metric is 1, traffic share count is 1

The following traceback may also be seen:

Jan 4 10:42:33.357 ROUTER: %IPRT-3-NDB_STATE_ERROR: NDB state error (BAD EVENT STATE)

(0x00) 192.168.116.152/30, state 7, event 2->1, nh_type 1 flags 4 -Process= "RIP

Router", ipl= 0, pid= 494

The updated route will no longer be visible in the forwarding plane.
