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.
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).

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.
