Delete a Node

You can delete a node from the topology when the node is decommissioned from the network. Since the nodes are decommissioned, deleting the nodes has no effect on the existing network. Pathfinder clears the application data associated with the deleted node (such as topology display and license count).

You can delete a node from the topology only if:

  1. The node is isolated, which means all the links associated with the node are deleted. For information about deleting links, see Delete a Link.

  2. The node does not have IS-IS, OSPF, or Path Computation Element Protocol (PCEP) adjacencies. Pathfinder clears the IS-IS and OSPF adjacencies when Toposerver receives a NODE WITHDRAW message from BGP Monitoring Protocol (BMP) and and clears the PCEP adjacencies when the PCEP session is terminated.

To delete a node from the topology:

  1. Click Network > Topology.

    The Topology page appears.

  2. On the Node tab, select the node that you want to delete.
  3. Click the delete (trash can) icon.

    A confirmation message appears.

  4. Click Yes.

    The node is deleted from the topology map and is removed from the network information table.
