BGP Commands
configure bgp neighbor maximum-prefix
configure bgp neighbor [<remoteaddr> | all] {address-family [ipv4-unicast |
ipv4-multicast]} maximum-prefix <number> {{threshold <percent>} {teardown
{holddown-interval <seconds>}} {send-traps}
Description
Configures the maximum number of IP prefixes accepted from a BGP neighbor.
Syntax Description
Default
This feature is disabled by default.
The default threshold is 75%.
By default, teardown is not specified.
By default, send-traps is not specified.
If no address family is specified, IPv4 unicast is the default.
Usage Guidelines
Configure the peer group before configuring the neighbors. To configure the peer group, use the
following command:
configure bgp peer-group maximum-prefix
Example
The following command configures the maximum number of IP prefixes accepted from all neighbors to
5000, sets the threshold for warning messages to 60%, and specifies SNMP traps:
remoteaddr Specifies an IP address of a BGP neighbor.
all Specifies all neighbors.
address-family The address family. BGP supports two address families: IPv4 Unicast and
IPv4 Multicast.
number Specifies the maximum number of prefixes that can be accepted. The range is
0 to 4294967294. A value of 0 disables prefix limit feature.
percent Specifies the percentage of the maximum prefix (threshold) at which a warning
message is printed in the log (and console), and/or a trap will be sent to the
SNMP manager.
teardown Specifies that the peer session is torn down when the maximum is exceeded.
seconds Specifies the length of time before the session is re-established, if the session
is torn down due to maximum prefix exceeded. If the hold-down interval is
zero or not specified, it is kept down until the peer is enabled. The range is 30
to 86400 seconds.
send-traps Specifies sending “number of prefix reached threshold” and “number of prefix
exceed the max-prefix limit” SNMP traps.
