BFD Protocol Configuration

NOTE:

Enable IP routing function before using this feature, for details please refer to Configuring IP Routing.

BFD Supports for OSPF, BGP, Static Route and ECMP

Configuring the Mode

There are two BFD modes: active and passive. The BFD will send protocol messages 'initiatively' in active mode and 'passively' in passive mode.

XorPlus# set protocols bfd mode active

Configuring Detect-Multiplier, Min-Receive-Interval and Min-Transmit-Interval

Detect-multiplier: a detection timeout multiple. It is used in calculating detection timeout time by the detector.

Min-receive-interval: the minimum sending interval of the BFD packet supported by the local side.

Min-transmit-interval: the minimum receiving interval of the BFD packet supported by the local side.

XorPlus# set protocols bfd interface vlan25 detect-multiplier 5
XorPlus# set protocols bfd interface vlan25 min-transmit-interval 1000
XorPlus# set protocols bfd interface vlan25 min-receive-interval 2000
XorPlus# commit
