PNNI Summary Tables
Showing PNNI summary table
Use the following command to show the configured PNNI summary table:
PNNI specification defines that each PNNI node advertises the addresses that are
locally connected to it. Since it is not scalable that each node would advertise all of
its local RAs, PNNI defines a way that the node advertises only summaries of
addresses. For lowest level node, the ATM address of a switch 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. For lowest level
node, the address prefix of the switch is the default summary.

Note:
In a well-configured network, the switches' prefixes will be organized
according to their peer groups. This way, the default summaries on the default level
will match the ATM prefixes of the switches. See Appendix G, “Setting Address
Prefixes to Match Hierarchical PNNI” for more details about prefix assignment.
