Configuring Dynamic Selective Point-to-Multipoint LSPs

You can configure a dynamic selective point-to-multipoint LSP for a multicast VPN. The leaf nodes for a dynamic point-to-multipoint LSP can be automatically discovered using leaf automatic discovery routes. Selective provider multicast service interface (S-PMSI) automatic discovery routes are also supported.

To configure a dynamic selective point-to-multipoint provider tunnel, include the rsvp-te and label-switched-path-template statements:



rsvp-te label-switched-path-template (default-template
| lsp-template-name);

You can include these statements at the following hierarchy levels:

[edit routing-instances routing-instance-name provider-tunnel selective group address source source-address]
[edit logical-systems logical-system-name routing-instances routing-instance-name provider-tunnel selective group address source source-address]

The label-switched-path-template statement includes the following options:

default-template—Specify that point-to-multipoint LSPs are generated dynamically based on the the default template. No user configuration is required for the LSPs. However, the automatically generated LSPs include none of the common LSP features, such as bandwidth allocation and traffic engineering.
lsp-template-name—Specify the name of an LSP template to be used for the point-to-multipoint LSP. You need to configure the LSP template to be used as a basis for the point-to-multipoint LSPs. You can configure any of the common LSP features for this template.
