Incorrect packet forwards or traffic loss can occur due to a stale prefix entry present in the hardware TCAM of Catalyst 6000 / 6500 series switches that run CatOS system software
A Catalyst 6500 series switch that runs CatOS release 6.3.2 or earlier with Supervisor Engine 2/Multilayer Switch Feature Card 2, can sometimes forward packets for some subnets to the wrong next-hop. This issue occurs due to stale prefix entries present during the time when the hardware Telecommunications Access Method (TCAM) blocks are freed. The hardware can forward packets due to a match to those stale entries.
In other words, the switch sends packets to the incorrect next-hop. This can result in either routing loops or the use of an incorrect or non-optimal path.
