NAME

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

SYNOPSIS

    use Net::BGP::Notification;

    $error = new Net::BGP::Notification(
        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 = new Net::BGP::Notification(
        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.

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();
