128 Chapter 6 Configuring the Passport 8672ATM Module
209195-A
In the configuration shown in Figure56, the Passport 8672ATM Module has an
ATM 1483 PVC as the sole member of a VLAN configured for IP routing.
Figure 56 IP routing with ATM 1483 PVCs
This configuration requires the following procedures:
•“Creating a VLAN “byPort” and adding ports” on page119
•“Assigning IP addresses” on page129
•“Enabling RIP routing” on page 131
•“Configuring a null-encapsulation PVC” on page134
•“Associating the PVC with the VLAN” on page 1 34
Note: Because the spanning tree protocol (STP) is not supported on the
Passport 8672ATM Module, ensure that you have no parallel paths to the
destination.
Note: Each configured ATM 1483 PVC uses one VLAN. The Passport
8672ATM Module can be configured for a maximum of 256 VLANs per
MDA and a maximum of 512 VLANs per card.
