Chapter 55. BFD Configuration
Overview 55.1
BFD (Bidirectional Forwarding Detection) is a set of all-net uniform detection mechanism used for rapid
detection and monitoring of link or IP routing forwarding connectivity. To improve the performance of existing
networks, communication troubles can be detected rapidly between neighboring protocols so that a standby
communication channel can be quickly established.
BFD can establish sessions between two machines to monitor bidirectional forwarding paths between the two
machines and serve upper-level protocols. The served upper-level protocol notifies BFD of the one with which
the session is established. After the session is established through the three-handshake mechanism, no
reception of BFD control packets from the peer within the detection time or the number of dropped echo
packets outnumbering the allowed threshold causes trouble. This case is then reported to the upper-level
protocol for corresponding processing.
BFD Configuration Tasks 55.2
55.2.1 Activating Port BFD
Port BFD is not activated by default.
After port BFD is enabled, BFD configured through dynamic protocols takes effect.
Run the following command to achieve the previous purpose:
Command Purpose
bfd enable <cr> | [min_tx_interval <tx_value> min_rx_interval <rx_value>
multiplier <m_value>]
Activates port BFD.
Before the BFD session is established, the BFD control packets are transmitted in an interval of no less than 1
second so as to narrow down traffic. After the session is established, the BFD control packets are transmitted
in a negotiated interval so as to realize rapid detection. During the establishment of BFD session, the
transmission interval and detection time of BFD control packets are also determined via packet exchange. In
an effective BFD session, these timers can be modified through negotiation at any time without affecting the
session status. The timer negotiations at different BFD session directions are conducted independently and
the bidirectional timers can be different. The transmission interval for BFD control packets is the maximum
value between local min_tx_interval and peer min_rx_interval, that is to say, the comparatively slow part
decides the transmission frequency.
The detection time is Detect Mult in peer BFD control packets multiplied the negotiated transmission interval
of peer BFD control packets. If you increase min_tx_interval of the local end, the actual transmission interval
of BFD control packets on the local end cannot be modified until the packets reset by the peer's F field are
received, which ensures that the detection time is lengthened on the peer before the increase of the
transmission interval of BFD control packets on the local end. Otherwise, the detection timer on the peer may
time out.
