which the router will initiate the specified response.

Command Usage
◆
This command is used to control the maximum number of route prefixes that
can be sent by a neighbor. It provides a method to reserve resources for other
processes, or to prevent malicious attacks.
◆
If the threshold is specified, but neither the restart nor warning keywords are
used), the connection will be closed until the records are cleared with the
ip bgp command.
Example
In this example, the router warns when the number of route prefixes reaches 6, and
the connection will be closed when the prefixes hit 13.
Console(config-router)#neighbor 10.1.1.64 maximum-prefix 12 50
Console(config-router)#
This command configures the local router as the next hop for a neighbor in all
routing messages it sends. Use the no form to disable this feature.
