To do...
Enter system view
Configure the source IP
address of BFD echo
packets
Enter interface view
Enable BFD on the RIP
interface
Bidirectional detection in BFD control packet mode
Follow these steps to configure BFD for RIP (bidirectional detection in BFD control packet mode):
To do...
Enter system view
Create a RIP process
and enter RIP view
Specify a RIP neighbor
Enter interface view
Enable BFD on the RIP
interface
Unidirectional detection in BFD echo packet mode only works for RIP neighbors that are directly
connected, namely, one hop away from each other.
Using the undo peer command does not remove the neighbor relationship at once and therefore
cannot bring down the BFD session at once.
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:
Use the command...
system-view
bfd echo-source-ip ip-address
interface interface-type
interface-number
rip bfd enable
Use the command...
system-view
rip [ process-id ] [ vpn-instance
vpn-instance-name ]
peer ip-address
interface interface-type
interface-number
rip bfd enable
