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.

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.
