Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
4) Try to telnet to the router.
Workaround: There is no workaround.
CSCso50383
Symptoms: In a Cisco 7600 ring topology with TE-FRR configuration, traffic might get software
switched if the packet comes in on a interface and goes out of the same interface.
Conditions: This can happen in a toplogy like the following:
R1 -------------- R2 ---------------- R3 | | |---------------- R4 ------------------|
Link between R3 - R4 is protected via R3 -> R2 -> R1 -> R4 (typical ring topology). R1 and R3 are
the end points of a VC. Normally traffic will take the primary TE tunnel via R-> R4 -> R1. When
R3 -> R4 link is shut, traffic will go on the back tunnel, R3 -> R2 -> R1 -> R4. In R4, traffic will be
sent back on the incoming interface to R1, VC destination. Now in R4 traffic will get punted to RP
and route cached.
Workaround: There is no workaround.
Further Problem Description: These drops also ignore QoS markings and affect all service classes.
CSCso50484
Symptoms: An RSVP GR instance may not be created on a sub-interface. Additionally, the interval
of GR instance may change to 200 when the backup tunnel on the interface is flapped.
Conditions: The symptoms are observed after the shutdown and no shutdown commands are
executed on the main interface where the sub-interfaces are created. The other trigger is when the
backup tunnel on the interface is flapped.
Workaround: Unconfigure and reconfigure global RSVP GR.
CSCso50587
Symptoms: FRR Protection is failing after using the no shutdown backup tunnel command.
Conditions: The symptom is observed after adding for the first time an FRR flag over a TE tunnel
using the command tunnel mpls traffic-eng fast re-route.
Workaround: Use the shutdown command followed by the no shutdown command on the Primary
Tunnel.
CSCso50602
Symptoms: Router reloads after the show ip /jointfilesconvert/422273/bgp ipv4 mdt vrf command is entered.
Conditions: Occurred on a Cisco 7600 router running Cisco IOS Release 12.2(33)SRB2. Occurs
when the show ip /jointfilesconvert/422273/bgp ipv4 mdt vrf command entered with the ip address option, such as show ip
/jointfilesconvert/422273/bgp ipv4 mdt vrf abc123 x.x.x.x.
Workaround: The reload can be avoided by not using the IP address option with the ’show ip /jointfilesconvert/422273/bgp
ipv4 mdt vrf’ command. None of the other options available for this command will trigger a reload
CSCso50794
Symptoms: The show spanning-tree vlan <vlan id> interface port-channel <int id> command
shows only option as EFP, and all other alternate options are not available.
Conditions: The Symptom shows up whenever there is either port-channel interface or GigaEthernet
interface.
Workaround: There is no workaround.
CSCso51519
Symptoms: Paths with same next-hop may be marked as being multipath.
