Routing
The signaling for establishing SVC connections is transferred by referring to the
routing table maintained by each switch in the network.
routing table maintained by each switch in the network.
There are two types of routing table: static routing table and dynamic routing table.
the ATM Switch provides the ILMI (Integrated Local Management Interface) and
PNNI (Private Network-Network Interface) functions for preparing and revising
the dynamic routing tables. Static routing tables can also be revised manually.

ILMI Functions
ILMI is a function for learning the configuration data of neighboring equipment
when an end system is connected to a switch or when a switch is connected to
another switch.
when an end system is connected to a switch or when a switch is connected to
another switch.
The ILMI function includes a switch-terminal address registration function. This
function is triggered by a trap. The switch adds the inherent address of each
terminal to its network prefix and registers the result as the ATM address of each
terminal.
