ip bgp neighbor passive
Configures the local BGP speaker to wait for this peer to establish a connection. When enabled, the local 
BGP speaker will not initiate a peer session with this peer; in this sense, the BGP speaker is “passive.” 
When disabled, the local BGP speaker will attempt to set up a session with this peer.
ip bgp neighbor ip_address passive
no ip bgp neighbor ip_address passive
Syntax Definitions
ip_address
32-bit IP address of the BGP peer. 
Defaults
This command is disabled by default.
Platforms Supported
OmniSwitch 6850, 6855, 9000, 9000E
Usage Guidelines
• Use the no form of this command to disable passive peer behavior.
• By default BGP will initiate a session to a peer once the peer is configured, has an AS number, and is 
enabled. You can use this command to configure the local BGP speaker as passive and an outbound 
session will not be initiated to this peer. For such peers, BGP will always wait passively for the 
inbound session attempt. 
• The BGP peer is restarted after issuing this command.
