Configuring PNNI Routing
Configuring PVCs
Lucent ATM PVCs can be established over a PNNI routing domain as well as over a
routing domain that supports both VNN ATM and PNNI.
PNNI signaling establishes Lucent ATM PVCs over a PNNI routing domain, but you
do not need to configure the PVC addresses manually. PNNI signaling uses a unique
SPVC node prefix, which is automatically generated by each switch, as the destination
address. All SPVC node prefixes begin with the same four bytes (4900C07B).
PNNI routing does not require changes to the way you usually configure PVCs. For
information about configuring Lucent ATM PVCs, see Chapter 10, “Configuring
ATM PVCs.”
PVCs can be established with endpoints that are any combination of ATM UNI, Frame
Relay UNI, or PPP logical ports.
Configuring SVC and SPVC Parameters
PNNI routing can connect your network of switches using SVCs instead of PVCs.
Once you have configured the ATM NNI logical ports, you configure SVC prefixes or
addresses using an AESA or E.164 format. Addresses can also be “learned”
dynamically through address registration if Interim Link Management Interface
(ILMI) is enabled on UNI ports. If necessary, review Chapter 16, “About SVCs,” for
an overview of SVC addressing and address registration. To configure SVC prefixes
and addresses, see Chapter 17, “Configuring SVC Parameters.”
In addition to SVCs, PNNI routing can access switches using SPVCs. For information
about configuring SPVCs, see Chapter 18, “Configuring SPVCs.”
