BGP Commands
configure bgp peer-group maximum-prefix
configure bgp peer-group <peer-group-name> {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 for all neighbors in the peer group.
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 neighbors, use the
following command:
configure bgp neighbor 192.168.1.1 maximum-prefix
Example
The following command configures the maximum number of IP prefixes accepted from the peer group
outer to 5000, sets the threshold for warning messages to 60%, and specifies SNMP traps:
configure bgp peer-group outer maximum-prefix 5000 threshold 60 send-traps
name Specifies a peer group.
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 on the console). An SNMP trap can also be
sent.
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
has been torn down due to exceeding the max limit. If the hold down interval
is 0 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.
