VC Type 4 Configuration on PE-CLE Port

The customer-facing FastEthernet or GigabitEthernet port must be provisioned with EoMPLS and a
VC type 4 or type 5. Interface GigE 0.1 on card A and card C plays the VC type 4 role in
page
on page
To provision a VC type 4, which transport IEEE 802.1Q VLAN packets between two PE-CLE ML-Series
cards, perform the following procedure on the customer facing port, beginning in global configuration
mode:
Command
Step 1
Router(config)# mpls label protocol ldp
Step 2
Router(config)# interface loopback0
Step 3
Router(config-if)# ip address ip-address
255.255.255.255
Step 4
Router(config)# interface {GigabitEthernet |
FastEthernet} interface-number.sub-interface-
number
Step 5
Router(config-subif)# no ip address
Step 6
Router(config-subif)# encapsulation dot1Q
vlan-id

Loopback addresses are used to specify the peer ML-Series card's IP address.
LDP configuration is required. The default Tag Distribution Protocol (TDP) will not work.
EoMPLS uses LDP targeted session between the ML-Series cards to create the EoMPLS VCs.
The MPLS backbone must use an Interior Gateway Protocol (IGP) routing protocol, for example,
Intermediate System-to-Intermediate System (IS-IS) Protocol or Open Shortest Path First (OSPF).
Tag switching of IP packets must be enabled on the SPR interface for the PE-CLE ML-Series card.

18-1.

Purpose
Specifies LDP as the label distribution protocol.
LDP must be specified. The ML-Series card does not
operate EoMPLS with the default TDP as the label
distribution protocol.
Enters loopback interface configuration mode.
Assigns an IP address to the loopback interface. This
loopback IP addresses is used to identify the peer in the
EoMPLS point-to-point session.
No subnet mask is needed.
Specifies the Ethernet subinterface for the imposition
interface. Make sure the subinterface on the adjoining
CE equipment is on the same VLAN as this subinterface.
Disables the IP address if an IP address is assigned.
Enables the subinterface to accept 802.1q VLAN
packets. Make sure the VLAN ID is the same as the
VLAN ID on the adjoining CE equipment.
