Basic PNNI Configuration

Displaying the Summary Address Configuration

To display the ATM PNNI summary address configuration, use the following privileged EXEC
command:
Example
The following example shows the ATM PNNI summary address configuration using the show atm pnni
summary privileged EXEC command:
Switch# show atm pnni summary
Codes: Node - Node index advertising this summary
Type - Summary type (INT - internal, EXT - exterior)
Sup - Suppressed flag (Y - Yes, N - No)
Auto - Auto Summary flag (Y - Yes, N - No)
Adv - Advertised flag (Y - Yes, N - No)
Node Type Sup Auto Adv Summary Prefix

1 Int N Y Y 47.0091.8100.0000.0040.0b0a.2a81/104
2 Int N Y N 47.01b1.0000.0000.0000.00/80
Configuring Scope Mapping
The PNNI address scope allows you to restrict advertised reachability information within configurable
boundaries.
Note On UNI and IISP interfaces, the scope is specified in terms of organizational scope values ranging from
1 (local) to 15(global). (Refer to the ATM Forum UNISignaling 4.0 specification for more
information.)
In PNNI networks, the scope is specified in terms of PNNI levels. The mapping from organizational
scope values used at UNI and IISP interfaces to PNNI levels is configured on the lowest-level node. The
mapping can be determined automatically (which is the default setting) or manually, depending on the
configuration of the scope mode command.
In manual mode, whenever the level of node 1 is modified, the scope map should be reconfigured to
avoid unintended suppression of reachability advertisements. Misconfiguration of the scope map might
cause addresses to remain unadvertised.
In automatic mode, the UNI to PNNI level mapping is automatically reconfigured whenever the level of
the node 1 is modified. The automatic reconfiguration avoids misconfiguratio ns caused by node level
modifications. Automatic adjustment of scope mapping uses the values shown in Table 11-1.
Command Purpose
show atm pnni summary Displays a summary of the PNNI hierarchy.
