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 E-Series 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.
NOTE: When you set this option, the router accepts BGP prefixes only until the maximum configured value. After the maximum number is reached, the router drops any additional prefixes that it receives.
Defaults
threshold = 75

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.
