neighbor maximum-prefix

Control the number of network prefixes received.

Syntax

neighbor { ip-address | peer-group-name} maximum-prefix maximum [ threshold] [warning-only]

To return to the default values, use the no neighbor { ip-address | peer-group-name} maximum-prefix maximum command.

Parameters

ip-address	Enter the IP address of the neighbor in dotted decimal format.
peer-group-name	Enter the name of the peer group.
maximum	Enter a number as the maximum number of prefixes allowed for this BGP router. The range is from 1 to 4294967295.
threshold	(OPTIONAL) Enter a number to be used as a percentage of the maximum value. When the number of prefixes reaches this percentage of the maximum value, the software sends a message. The range is from 1 to 100 percent. The default is 75.
warning-only	(OPTIONAL) Enter the keyword `warning-only` to set the router to send a log message when the maximum value is reached. If this parameter is not set, the router stops peering when the maximum number of prefixes is reached.

Usage Information

If you configure the neighbor maximum-prefix command and the neighbor receives more prefixes than the neighbor maximum-prefix command configuration allows, the neighbor goes down and the show ip bgp summary command displays (prfxd) in the State/PfxRcd column for that neighbor. The neighbor remains down until you enter the clear ip bgp command for the neighbor or the peer group to which the neighbor belongs or you enter the neighbor shutdown and neighbor no shutdown commands.
