NOTIFICATION

  • Extracts the BGP configuration, change, and session status information from the message and updates the appropriate router attributes.

ADJCHANGE

BGP

MAXPFXEXCEED

  • Parses the relevant syslog message originating from Cisco or Juniper devices after exceeding the threshold for receiving maximum routes from a neighbor over a BGP session. When the bMaxPrefixExceed setting for BGPProtocolEndPoint is set to TRUE as a result of threshold being crossed, a notification (PrefixThresholdCrossed) is generated.

SYS

CONFIG_I

  • Does not extract any status information from the message.

  • Sends SNMP polls to the appropriate device to rediscover the device’s BGP-related objects.
