show path-computation-client status >> Status = New The NorthStar Controller Topology Server (Toposerver) associates PCEP sessions with the nodes in the topology learned from the network TED. If a PCEP session is established using a node’s management IP address, the Toposerver might not receive that IP address from the TED and the PCEP session will not be allowed to establish. Step | |
