Cisco Cisco IOS Software Release 12.2(14)SZ

Multipoint Virtual Circuits: Multipoint Virtual Circuits are not supported in Ethernet over MPLS 
on the Cisco 7304 router.

NSE-100 Restrictions: On Cisco 7304 routers using an NSE-100 and running Ethernet over MPLS, 
the PE interface facing the MPLS core must use one of the following encapsulations:

HDLC, Frame Relay, or PPP encapsulation if the T3 or POS interface is the PE interface facing 
the MPLS core.

AAL5 SNAP if the ATM interface is the PE interface facing the MPLS core.

ARPA or 802.1q if a GigabitEthernet or FastEthernet interface is the PE interface facing the 
MPLS core. SNAP is not supported on the interface facing the MPLS core for GigabitEthernet 
and FastEthernet interfaces.

Refer to the following documents for more information:

Ethernet over MPLS is supported on the the following platforms:

Cisco 12000 Series router. For information on which engines and line cards are supported, see the

 

Cisco 10720 Internet Router, which provides two line card slots. 

The top slot can contain either of the following uplink cards:

DPT uplink card equipped with two physical OC-48c/STM-16c ports with an aggregate 
bandwidth of 5 Gbps.

Console/Auxiliary card when using the Cisco 10720 Internet Router as an Ethernet-only router.

The bottom slot can contain one of the following access cards:

24-port FX Fast Ethernet access card, available in TX, FX multimode, and FX single-mode

4-port Gigabit Ethernet 8-Port 10/100 Ethernet TX access card

Cisco 7304

A Cisco 7304 using an NSE-100, EoMPLS can be run on the built-in Gigabit Ethernet port or 
on the PA-2FE port adapter.

For the Cisco 7304 router using an NPE-G100, Ethernet over MPLS is only supported on the 
built-in GigabitEthernet port on the NPE-G100, a PA-GE, or on a PA-2FE-FX 2-Port Port 
Adapter (which require a Cisco 7304 PCI Port Adapter Carrier Card for installation in a 
Cisco 7304 router).

Cisco IOS software is packaged in feature sets that support specific platforms. To get updated 
information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature 
Navigator dynamically updates the list of supported platforms as new platform support is added for the 
feature.
