Caveats
Resolved Caveats—Cisco IOS Release 12.0(33)S1
Conditions: The show mpls traffic-engineering tunnel command output may indicate "Removal
Trigger: setup timed out" status.
Workaround: Perform a shut/no shut on the interface or change the metric temporarily to force an
update with the tunnel mpls traffic-eng autoroute metric 1 command.
• CSCsk67111
Symptoms: Watchdog timeout seen after switchover.
Conditions: Occurs when high availability RPR mode is configured on a Cisco 7500 router.
Workaround: There is no workaround.
• CSCsk78725
Symptoms: While giving T1 controller configuration, the router crashes. This happenes on the
8-port multichannel T1/E1 8PRI PA (PA-MC-8TE1+).
Conditions: Occurs on a router running Cisco IOS Release 12.4(17.7) and Cisco IOS Release
12.4(17.4)T1.
Workaround: There is no workaround.
• CSCsk81155
Symptoms: OSPFv3 loses hello packets causing neighbors to flap.
Conditions: Occurs on a Cisco GSR router running Cisco IOS Release 12.0(32)S7 and later when
TE tunnels are configured.
Workaround: There is no workaround.
• CSCsk81725
Symptoms: All E6 line cards are holding incorrect output slot information in hardware CEF for
default route. At the same time, other E4+ and E2 LCs have no problem with hardware CEF.
Conditions: Unknown.
Workaround: Use the clear ip route 0.0.0.0 command.
• CSCsk82701
Symptoms: Hot Standby Routing Protocol (HSRP) Virtual IP address is unreachable. IP address
assigned to the interfaces is reachable.
Conditions: Problem was seen in GSRs with different SPAs. Problem occurs only when line card is
installed for the first time or if it is moved between slots. Problem only occurs if the same interface
is both configured for HSRP and assigned to VPN routing/forwarding (VRF) VRF.
interface GigabitEthernet3/0/0.5 ip vrf forwarding ip address X.X.X.2 X.X.X.X standby 1 ip
X.X.X.1 standby 1 priority 110 standby 1 preempt
Workaround: Reload active and standby router as if you reload only active there is a chance standby
router once become active may hit the problem. Or, remove the HSRP configuration before moving
the linecard.
• CSCsk98123
Symptoms: Tx traffic may get dropped due to a "precam 1 exception."
Conditions: This symptom is observed when vrf vlite and strict urpf are configured on the interfaces.
This happens in all releases when adjacency indexes between 65528 to 65531 are used in TX SRAM
Adjacency programming on line cards. This happens only on port 0. Strict URPF not a required
condition. It can happen without that.
