Open a Network That Already Has a Multicast Tree
Ensure that your network is configured properly with IP, MPLS and P2MP LSP tunnels.
If you already have a specification file ready for the network, you can use that. The specification file should already have P2MP tree configured in it. Alternatively, if you have the set of router configuration files with P2MP trees configured in them, then you can import the configuration files and create a NorthStar Planner spec network model.
The following figure shows an example specification file that has two P2MP trees configured: one called C_BLACK (centered at TORONTO) and another called C_BLACK_DIV (centered at DENVER). The two P2MP trees have the same leaf nodes.
The above figure is from IP/MPLSView and will be replaced with an equivalent NorthStar Planner figure shortly.
