Caveats
Resolved Caveats—Cisco IOS Release 12.0(33)S1
Symptoms: A standby route processor crashes with a traceback when multilink is
provisioned/unprovisioned continuously.

encountering this symptom during manual testing. This symptom occurs in branches based on Cisco
IOS Release 12.0S ONLY.
Workaround: There is no workaround.

Symptoms: Customer reporting intermitent loss of L2 tunnel with no error messages.
Conditions: Occurs on a Cisco 7500 router running Cisco IOS Release 12.0(31)S02y.
Workaround: There is no workaround.
CSCsm12723
Symptoms: Layer 2 Virtual Private Network (L2VPN) CoS (Class of Service) queue becomes
unallocated via the show policy-map int <> dlci <> output command after a L3VPN subinterface
with another policy-map is applied to the same interface.
Conditions: Occurs when both L2vpn and L3vpn under the same interface with different policy-map
on both of them.
Workaround: Delete and redefine the layer 2 QoS policy to the Data-Link Connection Identifier
(DLCI).
CSCsm17391
Symptoms: Some Intermediate System-to-Intermediate System (IS-IS) routes are missing in the
routing table.
Conditions: This occurs when some interfaces flap.
Workaround: There is no workaround.
CSCsm24189
Symptoms: 1choc12 ISE: PLIM might reset due to heartbeat failure.
Conditions: This happens when the following errors occur on the PLIM console: [2]T1:5 rx error(crc
or non-integer size) 5 [2]T1:5 rx error(crc or non-integer size) 5
And when one or more paths have PAIS.
Workaround: Reduce the TEMUX logging level to 0 as follows attach slot# plim logctl /dev/temux
0 And then clear the path AIS.
CSCsm26130
Symptoms: When removing a subinterface from the configuration that contains an IP address that
falls into the major net of the static route, the static route is no longer injected into the BGP table.
Since the route is not in the BGP table, it is not advertised to any peers.
Conditions: This symptom is observed with auto-summary enabled in BGP. A static summary route
is configured to null0 and is injected into the BGP table with a network statement.
Workaround: There are four possible workarounds:
1) Use an "aggregate-address" configuration instead of the static route to generate the summary. 2)
Remove auto-summary from the BGP process. 3) Enter the clear ip /jointfilesconvert/415844/bgp * command. 4) Remove
and reconfigure the BGP network statement for the summary route.
