Symptoms: A router CPU stays high (98 to 99 percent) for more than 6 minutes after
oif-per-mvrf-limit is set to 2000 lower than the actual total number of OIFs (14000), and all mroute
states are re-formed.
Conditions: When oif-per-mvrf-limit is set to a certain number lower than the total number of OIFs
in the MVRF.

CSCsx06756
Symptoms: Linecards crash.
Conditions: This symptom occurs when a shut/no shut is performed on the SFC card.
Workaround: There is no workaround.
CSCsx20177
Symptoms: “no int loopback” with “advertise passive-only” causes a stuck prefix.
Conditions: This symptom is observed on a Cisco 7600 series router that is using an RSP720 with
Cisco IOS Release 12.2(33)SRD.
Workaround:
Do not use “advertise passive-only”. Unconfiguring and reconfiguring this command clears the
stuck prefix.
Or with “advertise passive-only”:
First remove “passive-interface loopback” from router isis.
Then remove the interface via “no int loopback”.

Symptoms: VRF traffic incorrectly routed using default route in global routing table.
Conditions: This problem may occur if a BGP update is received from different route reflectors at
different times.
Workaround: There is no workaround.
