Net::BGP::Notification(3p)

NAME
"Net::BGP::Notification" - Class encapsulating BGP-4 NOTIFICATION message

SYNOPSIS
    use Net::BGP::Notification;

    $error = Net::BGP::Notification->new(
        ErrorCode    => $error_code,
        ErrorSubCode => $error_subcode,
        ErrorData    => $error_data
    );

    $error_code    = $error->error_code();
    $error_subcode = $error->error_subcode();
    $error_data    = $error->error_data();

DESCRIPTION
This module encapsulates the data contained in a BGP-4 NOTIFICATION message. It provides a constructor, and accessor methods for each of the Error Code, Error Subcode, and Error Data fields of a NOTIFICATION. It is unlikely that user programs will need to instantiate "Net::BGP::Notification" objects directly. However, when an error occurs and a NOTIFICATION message is sent or received by a BGP peering session established with the Net::BGP module, a reference to a "Net::BGP::Notification" object will be passed to the corresponding user callback subroutine. The subroutine can then use the accessor methods provided by this module to examine the details of the NOTIFICATION message.

METHODS
new() - create a new "Net::BGP::Notification" object

    $error = Net::BGP::Notification->new(
        ErrorCode    => $error_code,
        ErrorSubCode => $error_subcode,
        ErrorData    => $error_data
    );

This is the constructor for "Net::BGP::Notification" objects. It returns a reference to the newly created object. The following named parameters may be passed to the constructor.

  ErrorCode
This parameter corresponds to the Error Code field of a NOTIFICATION message. It must be provided to the constructor.

  ErrorSubCode
This parameter corresponds to the Error Subcode field of a NOTIFICATION message. It may be omitted, in which case the field defaults to the null (0) subcode value.

  ErrorData
This parameter corresponds to the Error Data field of a NOTIFICATION message. It may be omitted, in which case the field defaults to a null (zero-length) value.

throw() - create a Notification object and throw an exception

    Net::BGP::Notification->throw( same args as new );

error_code() - retrieve the value of the Error Code field

    $error_code = $error->error_code();

error_subcode() - retrieve the value of the Error Subcode field

    $error_subcode = $error->error_subcode();

error_data() - retrieve the value of the Error Data field

    $error_data = $error->error_data();
