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 command for the neighbor or the peer group to which the
neighbor belongs or you enter neighbor shutdown and neighbor no shutdown commands.
