threshold (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.
Defaults threshold = 75

Usage
Information
If you configure the neighbor maximum-prefix command and the neighbor receives more prefixes
than the neighbor maximum-prefix command configuration 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.
