Appendix B, Configuration Fields.

Editing the PNNI Summary Table

The PNNI specification defines that each PNNI node advertises the
addresses that are locally connected to it. Since it is not possible to specify
that each node advertises all of its local Reachable Addresses (RA), PNNI
defines a way that the node advertises summaries of its Reachable
Addresses. For the lowest level node, the ATM address of a device is the
switch default summary, as all directly connected hosts and edge devices
that use ILMI for address registration get the switch prefix as the prefix to
their address.
A separate PNNI Node Summary table exists for each of the five possible
node indices. The table for each node index contains a up to ten entries.
To view the PNNI Summary Table for a given index, select Configuration >
PNNI Summary Table > Index x, where x is the number of the index. The
PNNI Summary Table opens.

The PNNI Summary Table provides a list of all the defined summaries,
either manually or by default (i.e. the switch prefix).
