Information
If the neighbor maximum-prefix 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.

The TCP session is authentication and hence prevents the data from being compromised.
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.
Range: 1 to 100 percent.
Default: 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.
