About the Container LSP Tab

On the Container LSP tab of the network table (Observability > Network > Topology > Tunnels), you can view the information about the list of container LSPs in your network.

A container LSP is a logical grouping of sub-LSPs (also referred to as member LSP) that share the properties defined in the container LSP. Routing Director dynamically adds (splits) or removes (merges) sub-LSPs based on real-time network conditions, preventing over-reservation or under-utilization of resources.

You can enable the Container LSP Normalization toggle button on the Network Optimization Settings section of the Organization Settings page (Settings Menu > System Settings) and configure the required container LSP parameters, which are crucial for fine-tuning network performance.

Once these parameters are defined, Routing Director automatically calculates the necessary number of sub-LSPs and their respective bandwidth allocations based on real-time traffic conditions and predefined thresholds .

This automation ensures that your network is agile and responsive, adapting to varying traffic loads to maintain optimal data flow and reduce congestion.

Benefits of Container LSPs

  • Enhances network efficiency by distributing traffic across multiple paths, reducing congestion and maximizing bandwidth utilization.

  • Minimizes unused reserved bandwidth through the ability to split and merge sub LSPs.

Prerequisite

You need to ensure that LSP traffic statistics are available so that the Routing Director can estimate the BW requirement and perform container normalization correctly.

Enable the Traffic Engineering toggle button under the Analytics tab for the Device profile by navigating to the Device and Interface Profiles page (Inventory > Device and Interface Profiles). Without this data, the Routing Director cannot compute the required BW or perform effective splitting and merging actions on sub‑LSPs. For more information, see About the Device and Interface Profiles Page

Tasks You Can Perform

  • Create a container LSP—Click the + icon to create a container LSP, which defines the properties of sub-LSPs.

    For more information on creating a container LSP is, see Add a Container LSP.

  • View sub-LSPs—Select a container LSP on the table and click View > Sub LSPs. The Container Sub LSPs page appears and lists all sub‑LSPs associated with the selected container LSP. These sub-LSPs are dynamically added (split) or removed (merged) by Routing Director, based on real-time network conditions. When you select a sub-LSP, its path will be highlighted in the Topology map.

  • Delete a container LSP—Select the container LSP you want to remove and click the Delete (trash bin) icon. Click Yes to confirm the delete operation. The selected container LSP and it's associated subLSPs are removed from the ingress device and Routing Director

  • Download—Click Download to download container LSP-related data to your local system. The data is downloaded to your local system as a comma-separated values (CSV) file.

  • View details of a container LSP—Select a container LSP on the table and click More > Show Details to view the details of a container LSP.

  • To perform common actions such as filtering using advanced filter criteria and resetting preferences, see Network Table Overview.

Table 1: Fields on the Container LSP Table
Fields Description

Name

Displays the name of the container LSP.

Device A

 Displays the source of the container. This field identifies the ingress device of the sub‑LSPs associated with the container.

Device Z

 Displays the destination of the container. This field identifies the egress device of the sub‑LSPs associated with the container.

IP A

 Displays the IPv4 address of the ingress device of the container.

IP Z

 Displays the IPv4 address of egress device of the container.

Merging Bandwidth

Displays the bandwidth threshold for removing sub-LSPs during container normalization. The valid units are B or b (bps), M or m (Mbps). K or k (Kbps), or G or g (Gbps). If you specify a value without units, bps is automatically applied.

Splitting Bandwidth

Displays the bandwidth threshold for creating additional sub-LSPs during container normalization. The valid units are B or b (bps), M or m (Mbps). K or k (Kbps), or G or g (Gbps). If you specify a value without units, bps is automatically applied.

Minimum LSP Count

Displays the minimum number of sub-LSPs that should always exist.

Maximum LSP Count

Displays the maximum number of sub-LSPs that can exist.

Minimum LSP Bandwidth

Displays the minimum bandwidth that each sub-LSP of this container can be assigned during container normalization or when the container was initially created. The valid units are B or b (bps), M or m (Mbps). K or k (Kbps), or G or g (Gbps). If you specify a value without units, bps is automatically applied.
Maximum LSP Bandwidth

Displays the maximum bandwidth that each sub-LSP of this container can be assigned during container normalization . The valid units are B or b (bps), M or m (Mbps). K or k (Kbps), or G or g (Gbps). If you specify a value without units, bps is automatically applied.
