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 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 threshold, the switch software sends a message. The
range is 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 the neighbor maximum-prefix command is configured 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.
