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 ipv6 unicast summary command displays
(prfxd) in the State/PfxRcd column for that neighbor. The neighbor remains down
until you enter the capture bgp-pdu max-buffer-size command for the neighbor or the
peer group to which the neighbor belongs or you enter neighbor shutdown and
neighbor no shutdown commands.
