Step 4. Configure the source IP address of echo packets. 5. Enter interface view. 6. Configure the minimum interval for receiving BFD echo packets. 7. Configure the minimum interval for transmitting BFD control packets. 8. Configure the minimum interval for receiving BFD control packets. 9. Configure the detection time multiplier. 10. Configure the authentication mode on the interface. Command bfd echo-source-ip ip-address interface interface-type interface-number bfd min-echo-receive-interval value bfd min-transmit-interval value bfd min-receive-interval value bfd detect-multiplier value bfd authentication-mode { md5 key-id [ cipher ] key | sha1 key-id [ cipher ] key | simple key-id [ cipher ] password } Remarks Optional. The source IP address should not be on the same network segment as any local interface's IP address. Otherwise, a large number of ICMP redirect packets may be sent from the peer, resulting in link congestion. N/A Optional. For relevant information, see the description of the Required Min Echo RX Interval field in "BFD packet format." 400 milliseconds by default. Optional. For relevant information, see the description of the Desired Min TX Interval field in "BFD packet format." 400 milliseconds by default. Optional. For relevant information, see the description of the Required Min RX Interval field in "BFD packet format." 400 milliseconds by default. Optional. For relevant information, see the description of the Detect Mult field in "BFD packet format." 5 by default. Optional. By default, the interface operates in the non-authentication mode. In Figure 45 for example, if you configure the Desired Min TX Interval as 100 milliseconds, Required Min RX Interval as 300 milliseconds, and Detect Mult as 5 on Router A, and configure the Desired Min TX Interval as 150 milliseconds, Required Min RX Interval as 400 milliseconds, and Detect Mult as 10 on Router B, • The actual transmitting interval on Router A is 400 milliseconds, which is the greater value between the minimum interval for transmitting BFD control packets on Router A (100 milliseconds) and the minimum interval for receiving BFD control packets on Router B (400 milliseconds). 180

Optional.
The source IP address should not
be on the same network segment
as any local interface’s IP address.
Otherwise, a large number of
ICMP redirect packets may be sent
from the peer, resulting in link
congestion.

for example, if you configure the Desired Min TX Interval as 100 milliseconds, Required Min
RX Interval as 300 milliseconds, and Detect Mult as 5 on Router A, and configure the Desired Min TX
Interval as 150 milliseconds, Required Min RX Interval as 400 milliseconds, and Detect Mult as 10 on
Router B,
•
The actual transmitting interval on Router A is 400 milliseconds, which is the greater value between
the minimum interval for transmitting BFD control packets on Router A (100 milliseconds) and the
minimum interval for receiving BFD control packets on Router B (400 milliseconds).
