About the Topology Group Tab
A topology group, also referred to as a topology slice, is a subset of the nodes and links in a network. A topology group is identified by a slice ID. You must configure the Slices parameter for the required nodes or links to group them as a topology group.
You can configure the nodes and links in a network to form a topology group in one of the following ways:
- Edit the node and link parameters to specify one or more slice IDs (positive integers) in the Slices field. For more information, see Edit Node Parameters and Edit Link Parameters.
- Select the required nodes and links on the topology map to add a topology group. For more information, see Group Nodes and Links into a Topology Group.
All the network elements that are tagged with the same slice ID form a topology group and are listed under the Topology Group tab. You can use topology groups as a constraint to restrict tunnel routing within a topology slice. For more information, see Add a Single LSP.
When you select a topology group in the network information table, the nodes and links within the topology group are highlighted in yellow on the topology map.
Tasks You Can Perform
You can perform the following tasks on the Topology Group tab:
- Hide unrelated nodes and links. Select Hide Unrelated to show only the nodes and links within the selected topology group on the topology map.
- Edit the description for the topology group.
Select the topology group and click Edit (pencil icon). The Edit topology Group page appears. In the Description field, enter a description for the topology group, and click Edit. The updated description of the topology group is displayed on the network information table.
- Delete a topology group.
Select the topology group, and click the Delete (trash can) icon. On the confirmation message that appears, click Yes. The topology group is removed from the network information table.
Note:Before you delete a topology group, you must remove all the nodes and links within the topology group. To remove a node or link from a topology group, you must remove the slice ID value from the Slices parameter for the particular node or link. For more information, see Edit Link Parameters and Edit Node Parameters.
- View topology group details. From the More list, select Show Detail to view details about the nodes and links that are part of the topology group.
