Add EVPN Service Site Details

An EVPN service is provisioned on a collection of sites to exchange network traffic over a shared infrastructure with a common layer 2 technology such as Ethernet. Use the Site Settings section of the Add L2 VPN Service page to enter details of sites that you want to connect to the EVPN.

Note:

Ethernet VPN (EVPN) is the only L2VPN service supported in this release.

You configure the following in the Site Settings section:

General details (site ID, site VPN flavor, location, devices, and MAC loop prevention parameters) about the site. See Add EVPN Site.
Parameters for site network access (connection with the service provider network). See Add EVPN Site Network Access Parameters.

Add EVPN Site

Prerequisite

Before adding the EVPN service site details, you must create a new EVPN service instance and enter general details about the service. Follow steps 1 to 4 of the Add an EVPN Service Instance procedure to create a new instance and add EVPN service general details.

An EVPN site refers to the geographical area where the VPN service spans. To add an EVPN service site in the Site Settings section:

Click the add (+) icon on the top-right corner of the Sites section.

The Add Site page appears.
Enter site details by referring to Table 1.
Do any of the following:
- Click Cancel to exit the Add Site page without saving the changes you made.

Add EVPN Site Network Access Parameters

Prerequisite:

Add EVPN Site.

After you add a site for the EVPN service, you must configure the parameters for site network access (connection) between the site and the service provider network. An L2VPN site network access refers to a logical Ethernet connection from a site to the L2VPN service in the provider network.

To set site network access parameters:

Select and expand the site name in the Sites table.
Expand Site Network Access and click the add (+) icon above the Site Network Access table.
The Add Connection page appears.

Enter the network access ID and device reference values by referring to the following table:

Table 2: Network Access ID and Device Reference Parameters (L2VPN)
Field	Description
Network Access ID	Enter a unique ID for the connection between the site and the service provider network.
Device Reference	Click the drop-down list to select a CE device for the connection. The drop-down list displays the devices that you specified on the Add Sites page.

Expand Access Diversity and add the access diversity parameters. See Add Access Diversity Parameters for EVPN Site Network Access.

Expand Bearer and add the bearer parameters by referring to the following table:

Table 3: Bearer Parameters (L2VPN)
Field	Description
Strict	Set to True if the requested access type is a strict requirement. If the requested access type is a strict requirement, the service provider cannot connect the site using any other media. The default setting is False.
Type	Specify the access media type that the customer prefers to use. Ethernet is the only supported media type in this release.

Expand Connection and add the connection parameters. See Add Connection Parameters for EVPN Site Network Access.

Expand Availability and enter the values by referring to the following table:

Table 4: Availability Parameters (L2VPN)
Field	Description
Access Priority	Enter a value for site network access priority. Enter a value in the range 0 through 4,294,967,295. The default value is 100. The access priority parameter defines the preference for the site network access (connection) for load balancing and configuring primary or backup site connections. The higher the access priority value, the higher is the preference for the connection.
Redundancy Mode	Select the redundancy mode from the following options: all-active—In this mode, all nodes can forward traffic to and from the Ethernet segment. single-active—In this mode, only one node forwards traffic to and from the Ethernet segment.

Add service parameters for the site network access:

Expand Service > Service Bandwidth and click the add (+) icon above the Bandwidth table.
The Bandwidth page appears.

Enter the values by referring to the following table:

Table 5: Service Parameters (L2VPN)
Field	Description
Direction	Select the direction of service bandwidth: input-bw—Bandwidth download direction from the service provider network to the site. output-bw—Bandwidth upload direction from the site to the service provider network.
CBS	Enter the Committed Burst Size (CBS) in bytes per second. When network traffic does not utilize the configured Committed Information Rate (CIR), the unused bandwidth is accumulated up to a maximum limit defined by the CBS.
CIR	Enter the CIR or the maximum number of bits per second (bps) that an interface can send or receive. The service provider provides the CIR as the guaranteed bandwidth for network traffic that an interface can send or receive in one second, under normal line conditions.

Click OK.

The bandwidth values are listed in the Bandwidth table.
(Optional) Click the edit or delete icons above the Bandwidth table to edit or delete the entries.

Expand MAC address limit and enter the values by referring to the following table:

Table 6: MAC Address Limit Parameters (L2VPN)
Field	Description
Action	Specify the action to be taken when the upper limit for customer MAC addresses is exceeded. The service provider specifies a maximum number of MAC addresses that can be learned from a customer for a single service instance. Drop is the only action supported in this release. This action drops the packet when the maximum limit for MAC addresses is exceeded.
Limit Number	Specify the maximum number of MAC addresses that can be obtained from a customer for a single service instance. Enter a value in the range 0 and 4,294,967,295. The default MAC address limit number is 2.

Do any of the following:
- Click Cancel to exit the Add Connection page without saving the changes you made.
- Click OK to save the connection details you added.
  
  You are returned to the Add L2 VPN Service page and the connection you added is listed in the Site Network Access table.
