8 Bidirectional Forwarding Detection (BFD) Bidirectional forwarding detection (BFD) is a detection protocol that provides fast forwarding path failure detection. The Dell Networking OS implementation is based on the standards specified in the IETF Draft draft-ietf-bfd-base-03, and supports BFD on all Layer 3 physical interfaces including VLAN interfaces and port-channels Topics: • bfd all-neighbors • bfd disable • bfd enable (Configuration) • bfd enable (Interface) • bfd interval • bfd neighbor • bfd protocol-liveness • ip route bfd • ipv6 ospf bfd all-neighbors • isis bfd all-neighbors • neighbor bfd • neighbor bfd disable • show bfd neighbors • vrrp bfd neighbor bfd all-neighbors Enable BFD sessions with all neighbors discovered by Layer 3 protocols virtual router redundancy protocol (VRRP), intermediate system to intermediate system (IS-IS), open shortest path first (OSPF), OSPFv3, or border gateway protocol (BGP) on router interfaces, and (optionally) reconfigure the default timer values. Syntax Parameters bfd all-neighbors [interval interval min_rx min_rx multiplier value role {active | passive}] interval milliseconds (OPTIONAL) Enter the keyword interval to specify non-default BFD session parameters beginning with the transmission interval. The range is from 50 to 1000. The default is 200. min_rx milliseconds multiplier value role [active | passive] Enter the keyword min_rx to specify the minimum rate at which the local system would like to receive control packets from the remote system. The range is from 50 to 1000. The default is 200. Enter the keyword multiplier to specify the number of packets that must be missed in order to declare a session down. The range is from 3 to 50. The default is 3. Enter the role that the local system assumes: Bidirectional Forwarding Detection (BFD) 328
