Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: Occurs when there are 4,000 active point-to-point access PVCs configured on a single
port of a ATM-OC3 SPA of a Cisco 7600 series router. All of the PVCs have Routed Bridged
Encapsulation (RBE) configured. All the PVCs are up initially on both active and standby console.
If a shut/no shut is performed on the main interface, PVCs comes up on the active console but stays
in inactive state on standby. The PVCs do not come up on standby even after line card online
insertion and removal (OIR.
Workaround: There is no workaround.

Symptoms: With no traffic on a PA-A6-OC3SMi card, the max ICMP pings times are seen at 352
ms to 384 ms when testing to an ATM loopback diag. Min/avg are 1/4. This is seen with 1500-byte
packets.
Conditions: This symptom is observed with a 7206vxr backplane version 2.8- 2.11 with the
PA-A6-OC3SMi ATM card.
Workaround: There is no workaround.
Further Problem Description: This symptom is not observed with version 2.8- 2.11 with the
PA-A3-T3 card.
Sending 200, 1500-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:

Symptoms: In a scale BGP IPv6 (more than 500 VRFs), setup with redistribution enabled, during
bootup the CPU will be hogged. The BGP neighborhood will not be able to established.
Conditions: Occurs under the following scenario:
1. scale setup 2. BGP IPv6 3. redistribution enabled.
Workaround: There is no workaround.

Symptoms: Crash when bringing up more than 2,000 DHCP class aware sessions.
Conditions: This happens only for DHCP initiated sessions with class association, such as when
"initiator dhcp class-aware" is configured. Memory corruption might occur when multiple DHCP
sessions are being brought up. The corrupting pattern is the DHCP classname. The memory
corruption occurs when the configured DHCP class name is offered after the DHCP workspace for
the particular DHCP discover message has been cleared.
Workaround: There is no workaround.
• CSCsl04835
Symptoms: A route introduced by Conditional Route Injection is not removed from the iBGP peer
upon withdrawal.
Conditions: Consider this situation: Router B is a BGP router that has two eBGP peers, Router A
and Router C. In a situation where RTR_A advertises a prefix and RTR_B injects a more specific
prefix of it, the symptom is observed in two ways: 1. If RTR_A withdraws the advertised prefix, the
more specific prefix is removed on RTR_B, but this withdrawal is not sent to RTR_A and RTR_C.
2. If the conditional route injection configuration is removed on RTR_B, the more specific prefix is
removed on RTR_B, but this withdrawal is not sent to RTR_A and RTR_C.
Workaround: There is no workaround.
