The total number of both IPv4 and IPv6 listen range groups you can configure are 10.
Use the
no
command to deactivate the IPv4 BGP dynamic neighbors feature and delete an IPv4 listen
range and deassociate it with a specified peer template.
bgp listen {limit max-number | range network/length [inherit peer peer-template-name]}
no bgp listen {limit | range network/length [inherit peer peer-template-name]}
Parameters
limit max-number
Sets a maximum limit number of IPv4 BGP dynamic subnet range
neighbors. Number from 1 to 100. Default is 20.
range network/length
Specifies a listen subnet range that is to be created. length is the IP
prefix representing a subnet, and the length of the subnet mask in bits.
network is a valid IPv4 prefix.
inherit peer peer-template-
name
(Optional) Specifies a BGP peer template name that is to be associated
with the specified listen subnet range and inherited with dynamically
created neighbors. The template will be inherited with dynamically
created neighbors.
Default
The default is as follows: BGP dynamic neighbor inactive; subnets are not associated with a BGP listen
subnet range.
Command Mode
•
BGP Router Config
•
IPv6 Address Family Config
Example
The following commands show how to create a listen range with a template to be inherited with
dynamically created BGP neighbors.
(Routing)#configure
(Routing)(Config)#router bgp 100
(Routing)(Config-router)#bgp listen limit 10
(Routing)(Config-router)#bgp listen range 10.12.0.0/16
(Routing)(fionfig-router)#bgp listen range 10.27.0.0/16 inherit peer ABC
11-19 bgp log-neighbor-changes
Use this command to enable logging of adjacency state changes. Both backward and forward adjacency
state changes are logged. Forward state changes, except for transitions to the
Established
state, are
logged at the
Informational
severity level. Backward state changes and forward changes to
Established
are logged at the
Notice
severity level.
Use the
no
command to return the
command to the default.
