====== MPLS vpns ======

Within the [[wp>Multi-protocol_Label_Switching|MPLS]] VPN form, it is possible to define MPLS VPN's. Instead of fixed values, it's possible to use [[menu:build:templates:template_edit|parameterized]] values. \\
Although the term MPLS is used, this form and the information stored can also be used as a [[wp>Virtual_Routing_and_Forwarding#Simple_implementation|VRF lite]] configuration.

===== VRF id =====

The [[wp>Virtual_Routing_and_Forwarding|VRF]] id is used as a reference value within the system. It is possible to use this parameter within the configuration. This id is not the individual id for a VRF on a device, but the ID for this type of VRF on all devices.

===== VRF name =====

The actual name of the VRF. This can be parameterized, so it will have a name related to the device it is provisioned on.

===== Client type =====

The [[menu:design:client_types|Client type]] where this VRF can be used.

===== VRF AS =====

The [[wp>Autonomous_System_|Autonomous System]] number which will be used within the VRF configuration.

===== VRF Route distinguisher =====

The [[wp>Route_distinguisher|Route distinguisher]] used for this configuration. When using a VRF lite configuration, this setting is not necessary. We would recommend ''<nowiki>global.unique.ipv4.address.pe+vrf_id</nowiki>'' (([[http://blog.ipspace.net/2012/07/bgp-route-replication-in-mplsvpn-pe.html|http://blog.ipspace.net/2012/07/bgp-route-replication-in-mplsvpn-pe.html]])) as the route distinguisher. This setting had the highest probability of being global unique.

===== VRF Route target =====

The [[http://packetlife.net/blog/2013/jun/10/route-distinguishers-and-route-targets/|route target]] used for this configuration. Again, when using VRF lite, this setting is not necessary.

===== MPLS option 1 =====

Additional MPLS options, which is free format. This could be used for any value. Such as maximum route statements, or additional route target import or exports.

===== MPLS option 2 =====

Same as MPLS option 1.

===== MPLS_management =====

Set this option to 1 in case this VRF will be used for management, NetYCE will use the name entered at the //VRF name// field when transferring files for the following vendors: HP Comware 7, Huawei.

===== MPLS_type =====
To assist creating categories of Node VRFs, Mpls_types and Vrf_types can be used. These values are set in the [[menu:admin:setup:settings|General settings]].

The values for these attributes are defined in the 'Lookup' using the 'Mpls_type' variable of the 'Translation' class. As many entries as desired can be created using this lookup variable. These values will be presented as drop-down menu lists from which one value can be selected.
