Create MPLS-TP service

Multiprotocol Label Switching (MPLS) is a standards-approved technology for speeding up network traffic flow and making it easier to manage. MPLS involves setting up a specific path for a given sequence of packets, identified by a label put in each packet, thus saving the time needed for a router to look up the address to the next node to forward the packet.

Perform the following steps to create a new service in MPLS-TP domain:

NOTE: Before creating a MPLS-TP service, create MPLS tunnel on NNIs and set the UNI ports to 'VLAN only' or 'VLAN+PRIO' or 'VLAN+DSCP'.

1. Go to Configuration > Layer 2 > Services menu and click Complete Services option. Complete Services page is displayed.
2. Click (Create Service). A series of new windows will now be displayed for step-by step creation of a service.

• Step 1: General Attributes
  1. Enter a name for the service and select the Technologies as MPLS-TP.
  2. Do one of the following:

     > To create an ELINE service, select the Service Type as ELINE.

     > To create an ELAN service, select the Service Type as ELAN. For more information, refer to the topic Create ELAN services with full mesh for creating an ELAN service of Full Mesh type and topic Create ELAN services with Hub and Spoke for ELAN Hub and Spokes service.

  3. Do one of the following:

     > To create the service in Non Qos Domain, select the Domain as Non Qos Domain.

     > To create the service in Qos Domain, select the Domain as Qos Domain.

     > To create the service in any of the two domain, select the Domain as All Domain.

  4. Do one of the following:

     > To disable OAM on the service, select OAM as None from drop-down option.

     > To enable OAM on the service, select OAM as BFD Config. Select BFD Configuration parameters displayed.

     > To enable PWSM on the service, select OAM as Pw Status. Select PW Status Configuration parameters displayed.

  5. Select Enable PSC check box to enable Protection State Coordination, if desired.
  6. Select Enable CFM check box to enable Connectivity Fault Management, if desired.
  7. Select/enter values for remaining parameters as desired. Referring to the table General Attributes parameters and click Next.

• Step 2: Adding End Points
  1. Click Add on End Points page to choose the end point and the UNI port for the service.
  2. Under Network element column, select the desired node as 'endpoint' followed by a UNI port.

     There are two ways of searching the desired node from the list explained as follows:

     > Enter the IP address/user label of the node in the text box provided and click (Search Node by IP Address or UserLabel). Or,

     > Click (Add switches using map view) and select desired NEs from the Topology selection window launched. Click Done. Note that only one node can be added at a time.

  3. Do one of the following for the selected UNI port:

     > If Domain is selected as 'Non Qos Domain' or All Domain' on General Attributes page, enter the VLAN value only. For All Domain the UNI port can be associated with TCProfile and CoS-0.

     > If Domain is selected as 'Qos Domain', enter the VLAN value and associate a Priority Mapping Profile or DSCP Mapping Profile or a pair of TCProfile and COS values.

     To view the bandwidth utilization, click View BW. View Port BW Utilization window is displayed with the bandwidth utilization details of Ingress and Egress Port.

     To view the used VLAN range, click Show Used VLans. View Used VLAN Range(s) window is displayed with a list of used VLAN values for the selected port.

     

  4. Click Add Uni.
  5. Similarly, repeat step a to d (of Step 2: Adding End Points) to add another endpoint to the service. The VLAN value by default will be same as entered for first UNI port while other values can be changed as desired.

     An ELine service must have two end points as shown in the following figure:

     

  6. Click Next.

• Step 4: PseudoWires

The PseudoWires page of Create Service provides options to add or remove protection, selection of pseudowire path manually or automatic path detection, and MA configuration.

• To edit MA configuration parameters, select the MA Configuration tab and select or enter the required values.
• To create an unprotected/protected pseudowire, un-select/select (Protection) check box under PseudoWires column. The check box against the end points gets unchecked/checked simultaneously.following
• Pseudowire path selection can be done in two ways as follows:

To find path for the pseudowire automatically, do the following steps:

1. Enable Find Path button by selecting (Auto Path) check box and then select check box against the added end points. The check boxes will be selected by default.
2. Click Find Path. Path found successfully message is displayed.
3. Click OK and select the pseudowire endpoints (Sw1--Sw2) to see its path.

   Graphical representation of the pseudowire detected automatically is displayed under the View tab as shown in the following figure. Details of work path, excluded switches and excluded tunnels is available under Details:

   

NOTE: When finding the pseudowire path automatically, the user is provided an option to exclude switches/tunnels. Select Excluded Switches and Excluded Tunnels tab. Click Add button and select the desired nodes and/links. Click Exclude Nodes or Exclude Links followed by Done. Remove button can be used to delete the added data. Select Find Path. Pseudowire path is calculated once again, excluding the selected switches/tunnels in the path.

To find path for the pseudowire manually, do the following steps:

1. Uncheck (Auto Path) check box and then select the added endpoints (Sw1--Sw2). The Manual Path button is displayed under the View tab.
2. Click Manual Path. The topology selection window is displayed.

   

3. There are two ways in which the pseudowire path can be added, which is explained as follows:

   (i) Direct Path Selection: This option is used for direct path selection between two end points with no intermediate nodes in between.

   Select a direct path/link between the two selected end points (highlighted in black) and click Add Work. The pseudowire path is added and the link color changes from pink to blue. To add protection (if (Protection) check box was checked), select another path/link and click Add Protect. Click Done.

   The graphical representation of the pseudowire added is displayed on the PseudoWires page under View tab along with work and/ protect path details under Details column as shown in the following figure:

   

   (ii) Partial Link Selection: This option is used when the user has to add more than one link to create a pseudowire path between the two end points.

   Select the Partial Link Selection check box. Select the paths/links between intermediate node connecting the two selected end points using CTRL button and click Add Links. The paths/links gets highlighted in cyan color. Click Add Work. The pseudowire path is added and the link color changes from cyan to blue. To add protection (if (Protection) check box was checked), select Partial Link Selection check box again (if desired) and select another path/link. Click Add Links > Add Protect. Click Done. If path addition fails, the partial link selection will be reset.

   Graphical representation of the pseudowire added is displayed on the PseudoWires page under View tab along with work path details under Details column as shown in the following figure:

   

4. Click Next to view the summary of the service created.

   NOTE: An additional PW Status Info page will be displayed if OAM was selected as 'Pw Status' on General Attributes page. For more information refer to Step 4: PW Status Info in the topic Create MPLS-TP service with PWSM.

• Step 5: Advance Configuration

  Advance Configuration window is displayed when Enable LLF check box is selected in the General Attributes page. Enter the values against the desired attributes and click Next.

  

  NOTE: An error will be displayed if LLF is not supported on the source and destination nodes.
