Point-to-Multipoint LSP Configuration

To set up a point-to-multipoint LSP, you configure the primary LSP from the ingress router and the branch LSPs that carry traffic to the egress routers. In addition to the conventional LSP configuration, you specify a path name on the primary LSP and this same path name on each branch LSP.

By default, the branch LSPs are dynamically signaled by means of CSPF and require no configuration. You can alternatively configure the branch LSPs as a static path.
