z
Unidirectional detection in BFD echo packet mode only works for RIP neighbors that are directly
connected, namely, one hop away from each other.
z
Using the
undo peer
command does not remove the neighbor relationship at once and therefore
cannot bring down the BFD session at once.
z
For RIP configuration, refer to
RIP Configuration
in the
IP Routing Volume
.
Configuring BFD for BGP
The default BGP keepalive interval is 60 seconds and can be configured as 1 second at least. Thus, the
holdtime is 180 seconds by default and three seconds at least. This makes the detection of neighbor
relationships rather slow, and a large quantity of packets will be dropped when being transmitted or
received through a high-speed interface. BFD quickly detects neighbor relationships and reduces
network convergence time. Before configuring BFD for BGP, you need to enable BGP.
Follow these steps to enable BFD for a BGP peer:
