neighbor maximum-prefix
Control the number of network prefixes received.
Syntax
neighbor {ipv6-address | peer-group-name} maximum-prefix maximum
[threshold] [warning-only]
To return to the default values, use the no neighbor {ipv6-address | peer-group-name}
maximum-prefix maximum [threshold] [warning-only] command.
Parameters
ipv6-address Enter the IPv6 address in the x:x:x:x::x format.
NOTE: The :: notation specifies successive hexadecimal fields of zeros.
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.
Defaults threshold = 75

Usage
Information
If you configure the neighbor maximum-prefix command and the neighbor receives more prefixes
than allowed by the neighbor maximum-prefix command configuration, the neighbor goes down
and the show ip bgp ipv6 unicast summary command displays (prfxd) in the State/PfxRcd
column for that neighbor. The neighbor remains down until you enter the capture bgp-pdu max-
buffer-size command for the neighbor or the peer group to which the neighbor belongs or you enter
neighbor shutdown and neighbor no shutdown commands.
