Oracle BFD implements the Bidirectional Forwarding Detection described in the RFC 5880. BFD is a detection protocol designed to provide fast forwarding-path failure detection times for media types, encapsulations, topologies, and routing protocols. BFD detects forwarding path failures at a uniform rate, rather than the variable rates for different protocol hello mechanisms. BFD makes network profiling and planning easier and reconvergence time consistent and predictable. BFD provides subsecond failure detection between two adjacent devices and can be less CPU-intensive than protocol hello messages, because some of the BFD load can be distributed to the data plane on supported modules.
Oracle BFD supports path monitoring for the following protocols:
· Static IPv4 & IPv6
· BGP
· OSPF
· MPLS
Linux IP support for BFD is provided and the configurations are same as mentioned in this document. The supported protocols for BFD in Linux IP are static route, OSPF, and BGP in IPv4, and static route and BGP in IPv6. This document describes how to configure Oracle BFD running as a part of Sun Ethernet Fabric Operating System (SEFOS).
BFD is configurable and managed by CLI. For more information about the command modes of CLI, see CLI Command Modes.
The following table lists the default values assigned to several BFD parameters, during the start-up of the router.

The following figure is an example of BFD configuration.
The figure depicts the components used in the topology, which are described as follows:
· R1, R2, and R3 represent routers in which SEFOS is installed.
· VLAN2 and VLAN3 represent the VLAN interfaces of the SEFOS routers.
· Each SEFOS switch has a router ID.
This table lists the IPv4 and IPv6 addresses of the interfaces and hosts provided in the figure.

The Oracle BFD software is designed in accordance with the FSAP2 (Flexible Software Architecture for Portability) to ensure a high level of portability
This chapter describes the preliminary configurations and the configurations for the topologies of Oracle BFD. You can configure the Oracle BFD feature by accessing Global Configuration mode or Interface Configuration mode. The configuration steps described in this document begin with accessing one or both of these modes.
This chapter describes the configuration of the Oracle BFD features using CLI.
· Configuring BFD over Static IPv4 & IPv6 paths
· Configuring BFD over OSPF
· Configuring BFD over BGP
The figure in the BFD Topology Example depicts the topology setup for this configuration.
Note: For the enterprise package, ports are automatically mapped to default switch.

This feature enables you to monitor IP neighbor reachability by using BFD. You can configure the neighbor statically. IP moves static routes (with next hop as neighbor) to pending state when BFD notifies that the neighbor is not reachable.
This feature enables you to monitor IPv6 neighbor reachability using BFD. You can configure the neighbor statically. IPv6 moves static routes (with next hop as neighbor) to pending state when BFD notifies the neighbor is not reachable. Refer to the Sun Ethernet Fabric Operating System IPv6 Administration Guide for static configurations.
This feature enables OSPF to detect its neighbor unreachable faster. BFD reports neighbor unreachable to OSPF as soon as it detects BFD packet failure. This speeds up convergence.
This feature enables OSPFv3 to detect its IPv6 neighbor unreachable faster. BFD reports neighbor unreachable to OSPFv3 as soon as it detects BFD packet failure. This speeds up convergence. Refer to the Sun Ethernet Fabric Operating System OSPFv3 Administration Guide for detailed configuration.
This feature enables BGP to detect its IPv4 and IPv6 remote neighbor unreachable faster. BFD reports neighbor unreachable to BGP as soon as it detects BFD packet failure. This speeds up convergence. Refer to the Sun Ethernet Fabric Operating System BGP administration Guide for detailed configuration.
