Command Reference Guide
transport connection-mode
Use the transport connection-mode command to specify Border Gateway Protocol (BGP) transport
session options for the BGP neighbor. This command can be used for BGP neighbors on the default or
nondefault VPN routing and forwarding (VRF) instance. Use the no form of this command to return the
connection mode to the default value. Variations of this command include:
transport connection-mode active
transport connection-mode passive
Syntax Description
active
passive
Default Values
By default, both active and passive connections are supported simultaneously, and a collision detection
algorithm is used to determine which TCP session to use should an inbound and outbound connection
begin.

Release 18.3
Functional Notes
The transport connection-mode command can be used to specify the connection mode for this BGP
neighbor on either the default or nondefault VRF instance. If the neighbor is to be created on a nondefault
VRF instance, the VRF instance must first be created using the command
on page 1460. Once you have created the nondefault VRF instance, you can configure the BGP neighbor
settings for the VRF instance using the command
Configuration mode. For example, to configure the BGP neighbor characteristics for the nondefault VRF
instance RED1, enter the following commands:
(config)#vrf RED1 route-distinguisher ip 192.17.250.24:33
(config)#router bgp 100
(config-bgp)#vrf RED1
(config-bgp-vrf)#neighbor 10.20.1.1
(config-bgp-vrf-neighbor)#
For more information about VRF and Multi-VRF BGP configuration, refer to the configuration guides

Specifies that only active Transmission Control Protocol (TCP) session
connections are allowed for this neighbor. Active connections are those that
are initiated by the router to establish a TCP connection to the neighbor.
Specifies that only passive TCP session connections are allowed for this
neighbor. Passive connections are those in which the router is only allowed
to listen for incoming BGP connections without trying to establish a
connection.
