Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: BGP backdoor functionality is not working.
Conditions: This symptom occurs after using the clear ip /jointfilesconvert/422273/bgp * command.
Workaround: Use the clear ip route * command.
• CSCsl66291
Symptoms: In a Resilient Ethernet Protocol (REP) topology a hardware flood layer (HFL) packet is
received on a node, but one of the REP interfaces is shut down.
Conditions: REP needs to notify hardware flood layer (HFL) and anything over MPLS (AToM)
clients about the VLAN list on the REP port along with the HFL notification, but in the above
scenario it will send a list of all 4000 VLANS, causing non-REP related VLAN MAC addresses to
be flushed as well.
Workaround: There is no workaround.
• CSCsl68034
Symptoms: Traffic might fail on Distributed Multilink PPP (dMLP) bundles when the SPA online
insertion and removal (OIR) is done.
Conditions: Occurs when a OIR is performed on a SPA with SIP-200 and Cisco 7600 router
configured for dMLP bundles with member links from a SPA.
Workaround: OIR of the SIP-200 line card will bring back the traffic up.
• CSCsl69206
Symptoms: Ping does not pass through GRE tunnel which is a VPN routing/forwarding (VRF)
member after second stateful switchover.
Conditions: This occurs after a stateful switchover has happened twice on the router.
Workaround: Reload the router.
• CSCsl69838
Symptoms: MPLS-TE Fast Reroute is failing upon switching from active to backup tunnel
configured on SPA-5X1GE-V2 in SIP-400. The backup TE tunnel is activated as expected but no
traffic is sent on it.
Conditions: MPLS-TE Fast Reroute node protection is configured using network interfaces on
SIP-400.
Workaround: The problem does not occur when the network interfaces are configured on SIP-600.
• CSCsl70148
Symptoms: On bootup with the 200 multicast-enabled, point-to-point, crypto GRE configuration,
the tunnels are not installed in hardware and the entries are continuously deleted and recreated.
Conditions: No explicit commands are run. This happens when booted with the above configuration
and Cisco IOS Release 12.2(SX)F12.
Workaround: There is no workaround.
• CSCsl70175
Symptoms: A router running Cisco IOS may crash if a sequence of configuration commands like the
following is entered at the prompt:
router eigrp 101 redistribute /jointfilesconvert/422273/bgp 300 router eigrp 101 redistribute /jointfilesconvert/422273/bgp 200
The crash is not specific to redistribution commands under EIGRP; entering two redistribute /jointfilesconvert/422273/bgp
<AS> commands with different AS numbers anywhere could trigger the crash.
