7-44 neighbor maximum-prefix
This command is used to control how many prefixes can be received from a neighbor. Use the no form of this
command to return to the default value.

DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide
This example shows how to configure the BGP neighbor 172.16.1.1 not to sent
advertisements about any path through the adjacent autonomous system 123.
Firstly, create an ip as-path access-list named 'myacl'.
Then, set the routing policy to neighbor 172.16.1.1
Specifies the IP address of the BGP peer.
Specifies the name of a Border Gateway Protocol (BGP) peer group. The maximum
length is 16 characters.
Specifies the maximum number of prefixes allowed from the specified neighbor. The
number of prefixes that can be configured is limited only by the available system
resources on a router.
(Optional) Integer specifying at what the percentage of the maximum prefix limit the
router starts to generate a warning message. The range is from 1 to 100. The
default is 75.
(optional) Allows the router to generate a sys-log message when the maximum-
prefix limit is exceeded, instead of terminating the peering session.
The default maximum number of prefix is 16000.
Peering sessions are disabled when the maximum number of prefixes is exceeded.
THRESHOLD: 75 percent.
Router Configuration Mode.
Address Family Configuration Mode (IPv4 Unicast, VPNv4 and VRF).
Level: 8. (EI Mode Only Command)
When the number of received prefixes exceeds the maximum number configured,
BGP disables the peering session (by default). You can use the clear ip bgp
command to re-establish the session. If the warning-only keyword is configured,
BGP sends only a log message and continues to peer with the sender.
Use the show ip bgp neighbors or show ip bgp peer-group command to verify
your settings.
