The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The BFD - VRF Support feature enables Bidirectional Forwarding Detection (BFD) support for Virtual Routing and Forwarding (VRF) on Provider Edge (PE) and Customer Edge (CE) devices to provide fast detection of routing protocol failures between the devices.
A BFD client establishes a Virtual Private Networking (VPN) session with devices that have BFD configured on them before requesting for session monitoring. However, there are no route lookups to determine whether a BFD neighbor is connected to the same VPN session or a different one. BFD relies on its client to get information about the VPN session to monitor the associated neighbor device. All information about VPN sessions is used to forward BFD control packets to the appropriate VPN through Cisco Express Forwarding (CEF).
