Configuring ATM Over MPLS Gateway Solution on CBX 3500
Configuring PWE3 Over MPLS Core Network
Pw Type Defines the encapsulation type to be carried over this PW
circuit. The value in this field is used in the PW Type field in
the PW ID FEC Element. Depending upon whether a VCC or
VPC is selected in the Administrative tab, the following
options are available:
• VCC
– ATM N:1 (N=1) VCC cell Transport
– ATM 1:1 VCC cell Mode
•VPC
– ATM N:1 (N=1) VPC cell Transport
– ATM 1:1 VPC cell Mode
EndPoint 1/EndPoint 2
Outbound Tnl Id Select a PSN tunnel from the pull-down list displaying PSN
tunnels configured between the two nodes selected for this
PWE3 circuit. The circuit will be bound to this tunnel for
outbound data.
If the selected tunnel is bi-directional, the selected tunnel for
EndPoint 1 will populate the Rmt Outbnd Tnl Id field for
EndPoint 2. Similarly, the Outbound Tnl Id selected for
EndPoint 2 will populate the Rmt Outbnd Tnl Id field for
Endpoint 1.
Rmt Outbnd Tnl Id Populated automatically, based on the tunnel selected in the
Outbound Tnl Id field.
Inbnd Label The PW/VC label used in the inbound direction (i.e. packets
received from the PSN). It may be set up manually if Pw owner
is Static. For Signaled (LDP) PWE3 PVCs, this field is not
required.
As per MPLS protocol, this is a 20-bit number. The minimum
is 16. The maximum is based on the Static Label range defined
in the MPLS parameters for the Node/Switch (see
“Configuring Node-based MPLS Parameters” on page 9-17).
Outbnd Label The PW/VC label used in the outbound direction (i.e. toward
the PSN). It represents the 20 bits of the PW/VC tag. It may be
set up manually if Pw owner is Static. For Signaled (LDP)
PWE3 PVCs, this field is not required.
