Border Gateway Protocol IPv4 (BGPv4) | 349
Parameters
Defaults
threshold = 75
Command Modes
ROUTER BGP
Usage
Information
If the neighbor maximum-prefix is configured and the neighbor receives more prefixes than allowed by
the neighbor maximum-prefix command configuration, 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 ipv4 unicast soft command for the neighbor or the peer
group to which the neighbor belongs or you enter neighbor shutdown and neighbor no shutdown
commands.

maximum
Enter a number as the maximum number of prefixes allowed for this BGP router.
Range: 1 to 4294967295.
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
