Parameters
source ip-address: Specifies the unicast source IP address of BFD sessions. The source IP address
cannot be 0.0.0.0.
destination ip-address: Specifies the unicast destination IP address of BFD sessions. The
destination IP address cannot be 0.0.0.0.
Usage guidelines
Make sure the source and destination IP addresses are consistent at two ends of an aggregate link.
For example, if you execute link-aggregation bfd ipv4 source 1.1.1.1 destination 2.2.2.2 on the
local end, execute link-aggregation bfd ipv4 source 2.2.2.2 destination 1.1.1.1 on the peer end.
The source and destination IP addresses cannot be the same.
The BFD parameters configured on an aggregate interface take effect on all BFD sessions in the
aggregation group. BFD sessions for link aggregation do not support the echo packet mode and the
Demand mode.
HPE recommends not configuring other protocols to collaborate with BFD on a BFD-enabled
aggregate interface.
Make sure the number of member ports in a BFD-enabled aggregation group is not larger than the
number of BFD sessions supported by the device. Otherwise, this command might cause some
Selected ports in the aggregation group to change to the Unselected state.
Examples
# Enable BFD for Layer 3 aggregation group 1, and specify the source and destination IP addresses
as 1.1.1.1 and 2.2.2.2 for BFD sessions.
