Configuring Pseudowire
The Cisco MWR 2941 also supports cell packing and PVC mapping for ATM over MPLS pseudowires.
Note Release 15.1(1)MR does not support ATM over MPLS N-to-1 Cell Mode or 1-to-1 Cell Mode.
For more information about how to configure ATM over MPLS, see Configuring Transportation of
Service Using ATM over MPLS. For sample ATM over MPLS configurations, see Configuration
Examples for Pseudowire.
Transportation of Service Using Ethernet over MPLS
Ethernet over MPLS (EoMPLS) PWs provide a tunneling mechanism for Ethernet traffic through an
MPLS-enabled Layer 3 core network. EoMPLS PWs encapsulate Ethernet protocol data units (PDUs)
inside MPLS packets and use label switching to forward them across an MPLS network. EoMPLS PWs
are an evolutionary technology that allows you to migrate packet networks from legacy networks while
providing transport for legacy applications. EoMPLS PWs also simplify provisioning, since the provider
edge equipment only requires Layer 2 connectivity to the connected customer edge (CE) equipment. The
Cisco MWR 2941 implementation of EoMPLS PWs is compliant with the RFC 4447 and 4448
standards.
For instructions on how to create an EoMPLS PW, see Configuring Transportation of Service Using
Ethernet over MPLS.
Limitations
When configuring an EoMPLS pseudowire on the Cisco MWR 2941, you cannot configure an IP address
on the same interface as the pseudowire.
Configuring Pseudowire
This section describes how to configure pseudowire on the Cisco MWR 2941. The Cisco MWR 2941
supports pseudowire connections using SAToP, CESoPSN, and ATM over MPLS. The following sections
describe how to configure pseudowire connections on the Cisco MWR 2941.
