项目中遇到了H3C设备使用IBGP和BFD的需求，总结如下。

RT1:

 bfd echo-source-ip 98.164.1.1
 bfd multi-hop min-transmit-interval 999
 bfd multi-hop min-receive-interval 999
 bfd multi-hop detect-multiplier 3

bgp 65164
 peer 98.164.1.2 as-number 65164
 peer 98.164.1.2 bfd multi-hop

RT2:

 bfd echo-source-ip 98.164.1.2
 bfd multi-hop min-transmit-interval 999
 bfd multi-hop min-receive-interval 999
 bfd multi-hop detect-multiplier 3

bgp 65164
 peer 98.164.1.1 as-number 65164
 peer 98.164.1.1 bfd multi-hop
