group-name} maximum-prefix maximum command.

Parameters

Enter the IP address of the neighbor in dotted decimal 
format.

Enter the name of the peer group.

Enter a number as the maximum number of prefixes allowed 
for this BGP router. The range is from 1 to 4294967295.

(OPTIONAL) Enter a number to be used as a percentage of 
the maximum value. When the number of prefixes reaches 
this percentage of the maximum value, the E-Series 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 prefixes is reached.

NOTE: When you set this option, the router accepts BGP 
prefixes only until the maximum configured value. After 
the maximum number is reached, the router drops any 
additional prefixes that it receives.
