Usage Information If you configure this command and the neighbor receives more prefixes than the configuration allows, the
neighbor goes down. To view the prefix information, use the show ip bgp summary command. The neighbor
remains down until you use the clear ip bgp command for the neighbor or the peer group to which the
neighbor belongs. The no version of this command resets the value to the default.
Example
OS10(conf-router-bgp-neighbor-af)# maximum-prefix 20 100 warning-only
Supported
Releases
10.3.0E or later
neighbor
Creates a remote IP peer and enters Neighbor Configuration mode.
Syntax
neighbor ip-address
Parameters
• ip-address — Enter the IPv4 or IPv6 address of the neighbor.
• interface interface-type — Enter the interface that connects to an unnumbered neighbor.
Default Not configured
Command Mode CONFIG-ROUTER-BGP
Usage Information
Create a remote peer with the BGP neighbor. Always enter the IP address of a BGP peer with this command. If
the configured peer address is a local IP address, the command does not validate.
NOTE: To configure these settings for a nondefault VRF instance, you must first enter the
ROUTER-CONFIG-VRF sub mode using the following commands:
1. Enter the ROUTER BGP mode using the router bgp as-number command.
2. From the ROUTER BGP mode, enter the ROUTER BGP VRF mode using the vrf vrf-name
command.
The no version of this command disables the BGP neighbor configuration.
Example
OS10(conf-router-bgp-2)# neighbor 32.1.0.0
OS10(conf-router-neighbor)#
