Determine the map type you want to view.

• maps that show IGP topology

• maps that show protocol-specific topologies

See To open a topology map from the NFM-P main menu for more information.

View the relationship between objects drawn on the map.

Manage checkpoints. See Chapter 18, Impact analysis for more information.

Update the LSDB, if required. See To update the LSDB for more information.

Create topology map groups, as required. See To create user-defined groups on topology maps for more information.

Synchronize the IGP topology map with the NFM-P physical topology map, or synchronize the OPSF, OSPFv3, or ISIS topology map with the IGP topology map. See To synchronize topology maps for more information.

Assign a router ID to an ISIS router with no TE router ID when the TopologyIsisSystemError alarm is raised, as required. See To assign a router ID to ISIS routers with no TE router ID for more information.

Open a flat map, if required. See To open a flat map for more information.

Manage filters for flat topology maps, if required:

1. Create a filter for the flat map. See To create a filter for flat maps for more information.

2. Apply a filter to the flat map. See To apply a filter to a flat topology map for more information.

Filter and list objects on topology maps, if required:

1. Filter the objects displayed on the topology map. See To filter objects displayed on a topology map for more information.

2. Filter the highlighted objects displayed on the topology map. See To filter highlighted objects displayed on a topology map for more information.

3. Remove selected references displayed on the topology map. See To remove specific references displayed on a topology map for more information.

4. List objects displayed on the topology map using a specific link. See To list objects using a selected link for more information.

5. List or view object information for objects displayed on the topology map. See To list or view object information from a map for more information.

View the legend information, if required. See To view the legends for a topology map .

Configure the type of information that is displayed on the CPAM topology map icon labels, if required. See To configure and view CPAM topology map icon labels for more information.

Configure the available menu options for IGP administrative domains, if required. See To configure available menu options for IGP administrative domains for more information.

Configure non-routed edge discovery policies to discover non-routed interfaces and subnets and represent them as adjacencies on the CPAM IGP and MPLS topology maps, if required. See To configure a non-routed edge discovery policy for more information.

Override non-routed edge discovery policies for specific routing interfaces to prevent network interfaces from being included in discovery calculations and from appearing on topology maps, if required. See To override a non-routed edge discovery policy for a routing interface for more information.
