Add a P2MP Group

Properties

Provisioning Method

Select PCEP or NETCONF. The default is NETCONF.

Provision Type

The default is RSVP, which is the only option supported for P2MP groups.

P2MP Group Name

Enter a user-defined name for the P2MP group. Only alphanumeric characters, hyphens, and underscores are allowed. Other special characters and spaces are not allowed.

Node A

Click the Node A field and select the name of the ingress (source) node from the list.

Node Z List

Click the Node Z field and select one or more egress (destination) nodes from the list.

Planned Bandwidth

Enter the planned bandwidth value. You must enter a number immediately followed by K (Kbps), M (Mbps), or G (Gbps). For example, 10M signifying 10 megabits per second.

Planned Metric

Enter the metric value for static tunnel. Use the up and down arrows to increment or decrement the value. For more information, see Basic LSP Configuration in MPLS Applications User Guide.

Setup

Enter the 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

Enter the 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.

Routing Method

Click the Routing Method list and select a routing method from the following:

• Admin Weight

• Constant

• Default

  Note:

  Do not change the routing method for PCEP-provisioned sub-LSPs; they should always have a routing method of “default”.

• Delay

• Distance

• ISIS

• OSPF

• Route by Device

Bandwidth Sizing

Toggle the button to enable bandwidth sizing. By default, this option is disabled.

Once enabled, configure the following parameters:

• Adjustment threshold (in percentage): Controls the sensitivity of the automatic bandwidth adjustment. The new planned bandwidth is only considered if it differs from the existing bandwidth by the value of this setting or more.

• Minimum and Maximum (planned) Bandwidth:

  If the new planned bandwidth is greater than the maximum setting, PathFinder signals the LSP with the maximum bandwidth.

  If the new planned bandwidth is less than the minimum setting, PathFinder signals the LSP with the minimum bandwidth.

  If the new planned bandwidth value is in between the maximum and minimum settings, Pathfinder signals the LSP with the new planned bandwidth.

• Minimum Variation Threshold: Specifies the sensitivity of the automatic bandwidth adjustment when the new planned bandwidth is compared to the current planned bandwidth. The new planned bandwidth is only considered if the difference is greater than or equal to the value of this setting. This can be used to prevent small fluctuations from triggering unnecessary bandwidth changes. If both the adjustment threshold and the minimum variation threshold are greater than zero, both settings are taken into consideration. In that case, the new planned bandwidth is considered if:

  • The percentage difference is greater than or equal to the adjustment threshold and

  • The actual difference is greater than or equal to the minimum variation.

Constraints

Enables you to configure administrative groups (link coloring) for bypass LSPs. For more information, see Assign Names to Admin Group Bits.

Admin Group Include All

Specifies the administrative groups whose links the bypass LSP must traverse. Select one or more bit-level link coloring options from the list.

Admin Group Include Any

Specifies the administrative groups whose links the bypass LSP can traverse. Select one or more bit-level link coloring options from the list.

Admin Group Exclude

Specifies the administrative groups to exclude for a bypass LSP. Select one or more bit-level link coloring options from the list.

Advanced

Description

Enter a description for the P2MP Group.

Diversity Group

Enter the name of a group of tunnels to which this tunnel belongs, and for which diverse paths is required.

Diversity Level

Select one of the following values for diversity level:

• Default (no diversity)

• Link

• Shared Risk Link Group (SRLG)

• Site

Site diversity is the strongest—it includes SRLG and link diversity. SRLG diversity includes link diversity. Link diversity is the weakest.

Custom Attributes

Simple name-value pairs which can be used to add any arbitrary customer-specific information. For example, to differentiate between properties for different vendor nodes.

To add custom properties associated with the node:

1. Click add (+) icon to add a new row.

2. Click the newly added row to enter the Name and Value.

3. Click the √ icon to save your changes.

Service

VPN Identifier

Select one of the following:

• MVPN instance: Select the multicast VPN instance as configured on the router.

• Route Distinguisher (RD): Populates automatically when you select the multicast VPN instance, if the information is available. If the field does not automatically populate, you can:

  • Obtain the RD from the head-end router configuration.

  • Run device collection for the head-end router from the Node tab of the network information table. Right-click the head-end router and select More > Run Device Collection. Once the collection completes, the RD field should auto-populate.

Flows

Define the (S,G) groups.

1. For each flow you want to add, click the add (+) icon to display a new line.

2. Enter the source and group (multicast traffic destination) IP addresses and mask.

The maximum number of flows (S,G groups) that you can successfully associate with a P2MP LSP depends on the traffic rate and group type (SSM or ASM), and is therefore, not a fixed number. If you surpass the maximum number of flows for the P2MP group, all the flows go into “Inactive (mapping successful)” state as viewed in the output of the show path-computation-client traffic-steering command on the router. To recover, delete the P2MP group and recreate it.

Schedule

Plan

Select one of the following options:

• No Schedule

• Once: Enter start and end date and time for a single event.

  1. Click the calendar icon on the right to display a monthly calendar from which you can select the year, month, and day.

  2. Click Select Time to enter a custom start time by scrolling up or down to select the hour, minute, and second along with AM/PM selection.

     Note:

     You can also click Now to select the current date and time.

  3. Click Ok.

     Note:

     You can also manually enter date and time values.

• Recurring Daily: Enter the start and end parameters for a recurring daily event (similar to the Once schedule).
