neighbor maximum-prex
Control the number of network prexes received.
Syntax
neighbor {ip-address | peer-group-name} maximum-prefix maximum [threshold]
[warning-only]
To return to the default values, use the no neighbor {ip-address | peer-group-name} maximum-
prefix maximum command.
Parameters
ip-address Enter the IP address of the neighbor in dotted decimal format.
peer-group-name Enter the name of the peer group.
maximum Enter a number as the maximum number of prexes allowed for this BGP router. The
range is from 1 to 4294967295.
threshold (OPTIONAL) Enter a number to be used as a percentage of the maximum value. When
the number of prexes reaches this percentage of the maximum value, the software
sends a message. The range is from 1 to 100 percent. The default is 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 prexes is reached.
Defaults threshold = 75

Usage Information If you congure the neighbor maximum-prefix command and the neighbor receives more prexes than the
neighbor maximum-prefix command conguration allows, the neighbor goes down and the show ip bgp
summary
command displays (prfxd) in the State/PfxRcd column for that neighbor. The neighbor remains down
until you enter the clear ip bgp command for the neighbor or the peer group to which the neighbor belongs
or you enter the neighbor shutdown and neighbor no shutdown commands.
Related Commands show ip bgp summary — displays the current BGP conguration.
neighbor password
Enable message digest 5 (MD5) authentication on the TCP connection between two neighbors.
Syntax
neighbor {ip-address | peer-group-name} password [encryption-type] password
To delete a password, use the no neighbor {ip-address | peer-group-name} password command.
Parameters
ip-address Enter the IP address of the router to be included in the peer group.
