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.

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.

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.
