Purpose
Command or Action
Creates a permanent virtual circuit for the ATM interface and assigns the PVC
with a VPI and VCI:
Router(config-subif)#
pvc vpi
/
vci
l2transport
Step 2
•
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 (only like-to-like
Xconnects and LS):
Router(cfg-if-atm-l2trans-pvc)#
encapsulation
{
aalo
|
aal5
}
Step 3
•
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
Step 4
{
encapsulation mpls
|
pseudowire-class
name
}
•
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 at both the ends of the pseudowire.
•
encapsulation mpls
sets MPLS in tunneling mode.
•
pseudowire-class name
specifies a pseudowire class that includes the
encapsulation mpls
command.
The
peer-router-id
and
vcid
combination must be unique on the router.
Note
Exits the interface configuration mode.
Router(config-if)#
exit
Step 5
Configuring the T3E3 ATM and T1E1 ATM SPAs in the Layer 2 Permanent Virtual Path (L2 PVP)
Mode
Perform the following steps to configure the T3E3 ATM and T1E1 ATM SPAs with ATM Cell Relay over
MPLS in the L2 PVP mode:
