Tunnel Layer and Layer 3 Routing Interaction

date_range 18-Nov-23

arrow_backward

arrow_forward

Modifications to the network model (e.g. tunnels, demands/flows, network elements, design options) usually require tunnels or flows to be rerouted. In NorthStar Planner, this rerouting occurs in the following order:

If you are in Layer 3 and a reroute is triggered, tunnels will be rerouted first, followed by demands/flows.
If you are in Tunnel Layer and a reroute is triggered, then only tunnels will be rerouted while in Tunnel layer. The moment you switch into Layer 3, however, the Layer 3 demands/flows will then be rerouted.
