hi,

Its possible to drop prefix update that exceeds specified threshhold on BGP , once the router drops the exceeded threshhold, a syslog message is generated on would either be sent to a syslog server or to the router buffer.

Hi,

snmp-server enable traps bgp [state-changes [all] [backward-trans] [limited] | threshold prefix]

together with Maxim Maximum-Prefix Configured for Warning-Only

might be the solution, see
