DETAILED STEPS
Purpose
Command or Action
Enables the privilege exec mode.
Router#
enable
Step 1
Enters the global configuration mode.
Router#
configure terminal
Step 2
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.
Router(config)#
interface atm
slot/subslot/port.subinterface point-to-point
Step 3
Creates a permanent virtual circuit for the ATM interface and assigns the
PVC a VPI ID and VCI ID:
Router(config-subif)#
pvc vpi
/
vci
l2transport
Step 4
•
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.
Note
Specifies the ATM adaptation layer (AAL) for the PVC:
Router(cfg-if-atm-l2trans-pvc)#
encapsulation
{
aalo
|
aal5
}
Step 5
•
aal0
—
Cell mode
•
aal5
—
Packet mode
Configures a pseudowire to transport data from the ATM interface across
the MPLS network.
Router(cfg-if-atm-l2trans-pvc)#
xconnect
peer-router-id vcid
{
encapsulation mpls
|
pseudowire-class name
}
Step 6
•
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.
