Symptoms: When you deconfigure IP version 6 (IPv6) or IPv6 unicast Reverse Path Forwarding (uRPF) on a Cisco router that runs IPv6 Cisco Express Forwarding (CEF), the configuration may not be removed from a Versatile Interface Processor (VIP) or line card, although it will be removed from the Route Switch Processor (RPS) or Route Processor (RP). This situation may cause IPv6 or IPv6 uRPF to continue to be applied to packets that are switched via distributed CEF (dCEF). Conditions: This symptom is observed on a Cisco 7500 series and Cisco 12000 series only when dCEF is enabled.
