Parameters
ip-address Enter the IP address of the neighbor in dotted decimal format.

Usage
Information
If you configure the neighbor maximum-prefix command 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 command for the neighbor or the peer group to which the neighbor belongs or you
enter the
neighbor shutdown and neighbor no shutdown commands.
