Configuring Network Routing
Network Clock Services for CES Operations and CBR Traffic
Circuit emulation services-interworking functions (CES-IWF) and constant bit rate (CBR) traffic relate
to a quality of service (QoS) classification defined by the ATM Forum for Class A (ATM adaptation layer
1 [AAL1]) traffic in ATM networks. In general, Class A traffic pertains to voice and video transmissions,
which have particular clocking requirements. For details, refer to Chapter 19, “Configuring Circuit
Emulation Services.”
Configuring Network Routing
The default software image for the ATM switch router contains the Private Network-Network Interface
(PNNI) routing protocol. The PNNI protocol provides the route dissemination mechanism for complete
plug-and-play capability. The following section, “Configuring ATM Static Routes for IISP or PNNI,”
describes modifications that can be made to the default PNNI or Interim-Interswitch Signalling Protocol
(IISP) routing configurations.
For routing protocol configuration information, refer to Chapter 10, “Configuring ILMI,”and
Chapter 11, “Configuring ATM Routing and PNNI.”
Configuring ATM Static Routes for IISP or PNNI
Static route configuration allows ATM call setup requests to be forwarded on a specific interface if the
addresses match a configured address prefix. To configure a static route, use the following command in
global configuration mode:
Note An interface must be User-Network Interface (UNI) or Interim Interswitch Signalling Protocol (IISP) to
be configured with static route. Static routes configured as PNNI interfaces default as down.
The following example shows how to use the atm route command to configure the 13-byte peer group
prefix = 47.0091.8100.567.0000.0ca7.ce01 at interface ATM 3/0/0:
Switch(config)# atm route 47.0091.8100.567.0000.0ca7.ce01 atm 3/0/0
Switch(config)#
Command Purpose
atm route addr-prefx atm card/subcard/port Specifies a static route to a reachable address
prefix.
