Chapter 10 Cisco IGX 8400 Series IP Service
IP Service—Functional Overview
URM
Note Except for the differences noted in this chapter, the URM can be configured as though it were an external
router and a UXM or UXM-E card. Switch software setup on the embedded UXM-E portion of the card
is the same as for a UXM or UXM-E, while the embedded router is configured like any external Cisco
router. For more information on the URM, see the Universal Router Module section on page 2-84.
The URM consists of a logically-partitioned front card connected to a universal router interface (URI)
back card. The front card contains an embedded UXM-E running an administration firmware image, and
an embedded router running a Cisco IOS image. The embedded UXM-E and the embedded router
connect through a logical internal ATM interface, with capability equivalent to an OC3 ATM port.
The logically-defined internal ATM interface is seen as a physical interface between the embedded
router and the embedded UXM-E processor. However, remote connections terminating on the URM can
use the internal ATM interface as an endpoint, with the embedded UXM-E processor passing
transmissions to the embedded router.
The URM supports the following types of IP service:
VoIP (with the URI-2FE2V back card)
IP+ATM, with VoATM (requires the URI-2FE2V back card)
IP+FR, with VoFR (requires the URI-2FE2V back card and uses FRF.8 service interworking
between the URMs internal ATM interface and the remote FR endpoint)
