Caveats
Resolved Caveats—Cisco IOS Release 12.0(6)S
This section describes possibly unexpected behavior by Cisco IOS Release 12.0(6)S. This section
describes only severity 1 and 2 caveats.
IP Routing Protocols
• CSCdk70273
If there are more than 31 OSPF interfaces, flooding does not work, starting from the 32nd OSPF
interface. There is no workaround.
• CSCdm34431
An RSP4 Route/Switch Processor that is running Cisco IOS Release 12.0(3.6)T or 12.0(4)T might
reload with the following error message if you issue the copy tftp running command to update the
configuration while the Versatile Interface Processor (VIP) or Route/Switch Processor (RSP) is
under a heavy traffic load:
ipfib_policy_forward vip_ip_fib_flow amdfe_rx_interrupt s_amdfe_check
This situation occurs when the RSP is running with a VIP2-50 Versatile Interface Processor, a Fast
Ethernet port adaptor, and PA-A3 and is configured with distributed Cisco Express Fowarding
(dCEF), policy routing, and NetFlow.
Workaround: Avoid reloading the configuration with the copy tftp running command.
• CSCdm51092
A Cisco router might reload if you enter the same no ip msdp mesh-group foo peer-address
command twice. There is no workaround.
• CSCdm59659
When “debug ip icmp” is enabled on a line card in a Cisco 12000 series Gigabit Switch Router
(GSR), it cannot be disabled. There is no workaround.
• CSCdm60244
A Cisco router might reload if you perform a router_id change or issue the
clear ip bgp {*} command when Multicast Border Gateway Protocol (MBGP) is enabled.
Workaround: Avoid issuing the clear ip bgp {*} command or changing router_id.
• CSCdm94032
Border Gateway Protocol (BGP) routes might not be withdrawn if deterministic med is not enabled.
Workaround: Configure deterministic med by issuing the bgp deterministic med command.
ISO CLNS
• CSCdm61381
A Cisco 2500 series router might reload if you issue the no router isis [tag] command. There is no
workaround.
