Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: MPLS frames that need to be encapsulated into VRF GRE tunnel are punted to RP if the
GRE tunnel requires MPLS imposition.
Conditions: This has been observed on Cisco 7600 provider edge (PE) routers in L3VPN
environment.
Workaround: There is no workaround.

Symptoms: The show ip ospf border-router may cause a router to crash.
Conditions: Occurs if the border table is recalculated in a significant way while the output is being
printed on the console. The risk of a crash is reduced if you avoid using the auto-more feature and
allow the entire output to display at once.
Workaround: There is no workaround.

Symptoms: Console may hang.
Conditions: Occurs when the TACACS+ server is being used as AAA server and the
single-connection option is configured.
Workaround: Remove the single connection option.

Symptoms: The following TOS settings tests fail on ES+ card:
* TOS mapping from inner to outer IP header via ip tos reflect on PW class.

Conditions: Occurs on a ES+ card configured for L2TPv3.
Workaround: There is no workaround.

Symptoms: Router crash is seen during ISSU with mls qos enabled.
Conditions: Occurs when user does ISSU from Cisco IOS Release 12.2(33)SRC2 to SRC3 or from
12.2(33)SRD1 to later SRD release.
Workaround: Disable QoS globally using the no mls qos command.
• CSCsy75784
Symptoms: Missing Intermediate System-to-Intermediate System (IS-IS) routes or routing loop
occurs after the edge router reloads several times.
Conditions: Occurs when MT-IPv6 is running and fast convergence parameters are configured.
Workaround: Enter the clear isis * command on the affected router.
