Provision LSP

 

To provision an LSP, navigate to Applications>Provision LSP. The Provision LSP window is displayed as shown in Figure 1.

Figure 1: Provision LSP Window, Properties Tab

Tab
Note

You can also reach the Provision LSP window from the Tunnel tab of the Network Information pane by clicking the Add button at the bottom of the pane.

As shown in Figure 1, the Provision LSP window has several tabs:

  • Properties

  • Path

  • Advanced

  • Design

  • Scheduling

From any tab, you can click Preview Path at the bottom of the window to see the path drawn on the topology map, and click Submit to complete the LSP provisioning. These buttons become available as soon as Name, Node A, and Node Z have been specified.

Table 1 describes the data entry fields in the Properties tab of the Provision LSP window.

Table 1: Provision LSP Window, Properties Fields

Field

Description

Name

Required. A user-defined name for the tunnel. Only alphanumeric characters, hyphens, and underscores are allowed. Other special characters and spaces are not allowed.

Node A

Required. The name or IP address of the ingress node. Select from the drop-down list. You can start typing in the field to narrow the selection to nodes that begin with the text you typed.

Node Z

Required. The name or IP address of the egress node. Select from the drop-down list. You can start typing in the field to narrow the selection to nodes that begin with the text you typed.

IP Z

IP address of Node Z.

Provisioning Type

Use the drop-down menu to select RSVP or SR (segment routing).

Path Type

Use the drop-down menu to select primary, secondary, or standby as the path type.

secondary (or standby) for

LSP name. Required and only available if the Path Type is set to secondary or standby. Identifies the LSP for which the current LSP is secondary (or standby).

Path Name

Required and only available if the provisioning type is set to RSVP. Name for the path.

Planned Bandwidth

Required. Bandwidth immediately followed by units (no space in between). Valid units are:

  • B or b (bps)

  • M or m (Mbps)

  • K or k (Kbps)

  • G or g (Gbps)

Examples: 50M, 1000b, 25g.

If you enter a value without units, bps is applied.

Setup

RSVP setup priority for the tunnel traffic. Priority levels range from 0 (highest priority) through 7 (lowest priority). The default is 7, which is the standard MPLS LSP definition in Junos OS.

Hold

RSVP hold priority for the tunnel traffic. Priority levels range from 0 (highest priority) through 7 (lowest priority). The default is 7, which is the standard MPLS LSP definition in Junos OS.

Planned Metric

Static tunnel metric. Type a value or use the up and down arrows to increment or decrement by 10.

Comment

Optional. Free-form comment describing the LSP.

The Path tab includes the fields shown in Figure 2 and described in Table 2.

Description

Selection

Use the drop-down menu to select dynamic, required, or preferred.

Hop 1

Only available if your initial selection is either required or preferred. Enter the first hop and specify whether it is strict or loose. To add an additional hop, click the + button.

The Advanced tab includes the fields shown in Figure 3 and described in Table 3.

Field

Description

Coloring Include All

Double click in this field to display the Modify Coloring Include All window. Select the appropriate check boxes. Click OK when finished.

Coloring Include Any

Double click in this field to display the Modify Coloring Include Any window. Select the appropriate check boxes. Click OK when finished.

Coloring Exclude

Double click in this field to display the Modify Coloring Exclude window. Select the appropriate check boxes. Click OK when finished.

Symmetric Pair Group

When there are two tunnels with the same end nodes but in opposite directions, the path routing uses the same set of links. Example, Tunnel1 source to destination is NodeA to NodeZ, and Tunnel2 source to destination is NodeZ to NodeA. Selecting Tunnel1-Tunnel2 as a symmetric pair group places both tunnels along the same set of links. Tunnels in the same group are paired based on the source and destination node.

Create Symmetric Pair

Select the checkbox to create a symmetric pair.

Diversity Group

Name of a group of tunnels to which this tunnel belongs, and for which diverse paths is desired.

Diversity Level

Use the drop-down menu to select the level of diversity as default, site, link, or SRLG.

Route on Protected IP Link

Select the check box if the route is to use protected IP links as much a possible.

The Design tab includes the fields shown in Figure 4 and described in Table 4.

Field

Description

Routing Method

Use the drop-down menu to select a routing method. Available options include default, adminWeight, delay, constant, distance, ISIS, and OSPF.

Max Delay

Type a value or use the up and down arrows to increment or decrement by 100.

Max Hop

Type a value or use the up and down arrows to increment or decrement by 1.

Max Cost

Type a value or use the up and down arrows to increment or decrement by 100.

High Delay Threshold

Type a value or use the up and down arrows to increment or decrement by 100.

Low Delay Threshold

Type a value or use the up and down arrows to increment or decrement by 100.

High Delay Metric

Type a value or use the up and down arrows to increment or decrement by 100.

Low Delay Metric

Type a value or use the up and down arrows to increment or decrement by 100.

Scheduling relates to bandwidth calendaring. By default, tunnel creation is not scheduled, which means that tunnels are provisioned immediately upon submission. Click the Scheduling tab in the Provision LSP window to access the fields for setting up the date/time interval. Figure 5 shows the Scheduling tab of the Provision LSP window.

Select Once to select start and end parameters for a single event. Select Daily to select start and end parameters for a recurring daily event. Click the calendar icon beside the fields to select the start and end dates, and beginning and ending times.

Note

The time zone is the server time zone.
