Cease Subcodes

the session. The cease subcodes currently supported are given in
Table 71.
The following sections provide detailed descriptions of each supported cease subcode.
Maximum Number of Prefixes Reached
This cease subcode is sent when the number of prefixes from a BGP neighbor exceeds the
pre-configured limit. The notification message contains additional data to indicate the
