set protocols bfd multihop peer local-address passive-mode

The set protocols bfd multihop peer local-address passive-mode command configures the BFD session as passive for a multi-hop BFD session.

The delete protocols bfd multihop peer local-address passive-mode command sets the configuration to the default value.

Command Syntax

set protocols bfd multihop [vrf <vrf-name>] peer<peer-ip> local-address <local-ip> passive-mode

Parameter

Parameter	Description
vrf <vrf-name>	Optional. Specifies a VRF name. The value is a string. It’s a user-defined VRF set by the command set ip vrf <vrf-name> [description <string>].
peer <peer-ip>	Specifies the peer for a BFD session. The value is an IPv4 or IPv6 address.
local-address <local-ip>	Specifies a local address used to send the packets. The value is an IPv4 or IPv6 address.

Usage Guidelines

A passive session will not attempt to start the connection and will wait for control packets from peer before it begins replying.
This feature is useful when you have a router that acts as a central node in a star network and you want to avoid all the other nodes sending BFD control packets.

Example

Configure the BFD session as passive.
