Net::ACL::RouteMapRule - Class representing a BGP-4 policy route-map rule



NAME

Net::ACL::RouteMapRule - Class representing a BGP-4 policy route-map rule


SYNOPSIS


    use Net::ACL::RouteMapRule;

    # Constructor

    $rule = new Net::ACL::RouteMapRule(

        Action  => ACL_PERMIT,

        Match   => {

                ASPath          => [ 'my-as-path-list' ],

                Community       => [ 'my-community-list' ],

                Prefix          => [ 'my-prefix-list' ],

                Next_hop        => [ 'my-access-list' ],

                Routesource     => [ 'my-access-list' ],

                MED             => 20,

                Origin          => IGP

                },

        Set     => {

                ASPath          => [ 65001, 65001 ],  # Prepend

                Community       => [ qw( 65001:100 65001:200 ) ],

                Next_hop        => '10.0.0.1',

                Local_Pref      => 200,

                MED             => 50,

                Origin          => EGP,

                Weight          => 42

                }

        );

    ($rc,$nlri) = $rule->query($prefix, $nlri);

    $rc = $rule->match($prefix, $nlri);


DESCRIPTION

This module represents a single route-map clause with a match part, a set part and an action. This object is used by the Net::ACL::RouteMap object. It inherits from Net::ACL::Rule, with the only changed method being the autoconstructor() method.


CONSTRUCTOR

new() - create a new Net::ACL::RouteMapRule object
The method is inherited from the Net::ACL::Rule object. But since the autoconstruction() method has been replaced, some extra named arguments below Match and Set are understood:
ASPath
When used in Match, the ASPath named argument should be a name of an ASPath access-lists.

When used in Set, it should be the AS numbers that should be prepended. They may be specified in anyway that the Net::BGP:ASPath->new() constructor allows them.

Community
When used in Match, the Community named argument should be a community-list.

When used in Set, it should be a list of communities to set.

Prefix
The Prefix named argument can only be used under Match. It's value should be a list of Net::ACL prefix-list names.

Next_hop
When used under Match, its value should be a list of names of access-lists.

When used under Set, its value should be an IP address.

Routesource
The Routesource named argument can only be used under Match. It's value should be a list of Net::ACL access-list names.

Origin
The Origin named argument should have a value of either IGP, EGP or INCOMPLETE, as exported by Net::BGP::NLRI :origin.

Local_Pref
MED
Weight
The Local_Pref, MED and Weight named argument should have values of integers.

Weight can only be used in Set.


ACCESSOR METHODS

query()
match()
The query() and match() methods take a Net::BGP::NLRI object as first argument and a prefix as second, but does and return the same as the match() and query() methods of the Net::ACL::Rule object.
