Conditions: This symptom is observed when there is a default route configured while running

Cisco IOS Release 120(32)SY4 or 120(32)SY6 on Eng3.

Workaround: Clear ip route 0.0.0.0 or <default-network>.

• CSCsr64777

Symptoms: A router crashes because of a block overrun (overwriting the memory block).

Conditions: This symptom is observed only when NetFlow version 5 is used.

Workaround: NetFlow version 9 could be used for exporting.

• CSCsr67137

Symptoms: An Engine 3 (E3) Channelized OC12 (CHOC12) line card can reload after a switchover

in Route Processor Redundancy Plus (RPR+) mode.

Conditions: This symptom is observed on a Cisco 12416 Internet series router. The router is booted

with Cisco IOS Release 12.0(32)S11n and contains the following:

–

Redundant PRP-2 processor running in RPR+ mode

–

E3 CHOC12 line card

–

All other slots in the chassis are populated with E3, E4+, and E5 line cards.

Workaround: There is no workaround.
