Cisco IGX 8400 Series IP Service
IP Service—Functional Overview
The Cisco IGX 8400 series delivers in-chassis IP routing through the Universal Router Module (URM),
a dual-processor card set delivering high-density voice and data interfaces. You can also set up IP
routing services using an external router and configuring ATM PVCs on the IGX.
IP service on the IGX functions through configuration of virtual slave interfaces (VSIs) that allow a node
to be managed by multiple label switch controllers (LSCs), such as Multiprotocol Label Switching
(MPLS).
Note Private Network-to-Network Interface (PNNI) is not supported on the URM.
This chapter primarily contains information related to MPLS support on the IGX using the URM. For
information on configuring MPLS using an external router, such as a Cisco 7200, see the Update to the
Cisco IGX 8400 Series Reference Guide for Switch Software Release 9.3.1.
For information on additional Cisco IOS features supported on the IGX, see the Cisco IOS documents
listed in the “Related Documentation” section on page viii.
Required Hardware and Software
Table 10-1 contains information on the hardware and software required to provision IP services across
an IGX node.
Note Refer to the Compatibility Matrix for Cisco IOS software, switch software, and firmware compatibility
requirements.
