  • Cisco Carrier Routing System

Known Affected Releases

3.9.0.BASE

Description (partial)

Symptom:
The MAC withdrawal message was delayed by 7 secs to prevent relearning of the faulty path in the case that the MAC withdrawal message arrives before the last packet from that failed datastream. However, in some scenarios,  this creates a situation where more  packets are losts than targetted.   

Condition:
An interface failure creates this situation if MAC withdrawal is enabled.
