Purpose
Enables the privilege exec mode.
Enters the global configuration mode.
Enters the subinterface configuration mode pertaining to the specified slot
and port number to establish a P2P connection in which the
SPA-2CHT3-CE-ATM is installed.
Creates a permanent virtual circuit for the ATM interface and assigns the
PVC a VPI ID and VCI ID:
Note
Specifies the ATM adaptation layer (AAL) for the PVC:
Configures a pseudowire to transport data from the ATM interface across
the MPLS network.

• vpi specifies the virtual path identifier (0 to 255).
• vci specifies the virtual channel identifier. Valid values are 32 to 1
less than the value specified using the atm vc-per-vp command.
Do not specify 0 for both the VPI and
VCI.
• aal0—Cell mode
• aal5—Packet mode
• peer-router-id is the IP address of the remote PE peer router.
• vcid is a 32-bit identifier that is to be assigned to the pseudowire. The
same vcid must be used for both ends of the pseudowire.
• encapsulation mpls sets MPLS for the tunneling mode.
