• Track. For more information, see "Configuring Track."
• IP fast reroute (FRR). IP FRR is supported by BGP, OSPF, RIP, IS-IS and static routing. For
more information, see Layer 3—IP Routing Configuration Guide.
• Link aggregation. For more information, see Layer 2—LAN Switching Configuration Guide.
Protocols and standards
• RFC 5880, Bidirectional Forwarding Detection (BFD)
• RFC 5881, Bidirectional Forwarding Detection (BFD) for IPv4 and IPv6 (Single Hop)
• RFC 5882, Generic Application of Bidirectional Forwarding Detection (BFD)
• RFC 5883, Bidirectional Forwarding Detection (BFD) for Multihop Paths
• RFC 5885, Bidirectional Forwarding Detection (BFD) for the Pseudowire Virtual Circuit
Connectivity Verification (VCCV)
Configuring BFD basic functions
Before configuring BFD basic functions, configure the network layer addresses of the interfaces so
that adjacent nodes are reachable to each other at the network layer.
After a BFD session is established, the two ends negotiate BFD parameters, including minimum
sending interval, minimum receiving interval, initialization mode, and packet authentication, by
exchanging negotiation packets. They use the negotiated parameters without affecting the session
status.
Configuring echo packet mode
To configure echo packet mode:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Configure the source IP
address of echo packets.
• Configure the source IP
address of echo packets:
bfd echo-source-ip
ip-address
• Configure the source IPv6
address of echo packets:
bfd echo-source-ipv6
ipv6-address
By default, no source IP address
is configured for echo packets.
The source IP address cannot be
on the same network segment as
any local interface's IP address.
Otherwise, a large number of
ICMP redirect packets might be
sent from the peer, resulting in
link congestion.
The source IPv6 address of echo
packets can only be a global
unicast address.
3. Enter interface view.

interface-type
interface-number
N/A
4. (Optional.) Set the minimum
interval for receiving BFD
echo packets.
bfd min-echo-receive-interval
value
By default, the minimum interval
for receiving BFD echo packets is
400 milliseconds.
5. (Optional.) Set the
single-hop detection time
multiplier.
bfd detect-multiplier
value The default setting is 5.
