Configuring VPLS
•
A T-LDP session is established between PE1 and PE2. The LSP tunnel path is setup between PE1 and
PE2.
•
The label distribution for the path between PE1 and PE2 is as follows:
PE2 - Host FEC with label pop (9.1.1.3,25)
PE2 - Host FEC with label pop (9.1.1.3/32,25)
Router 2 - Host FEC with push/swap (9.1.1.3,25/26)
On PE1(R1): Host FEC with label push (9.1.1.3/32,26)
Note. The label distribution path is in the opposite direction of the data flow.
Step 4: Configure a VPLS Service
Configure a VPLS service for customer ID 100 and bind the service with SDP 8. The service is created on
both Router 1 and Router 3 so that customer traffic is forwarded in both directions through the SDP
tunnel. Note that a service is not configured on transit Router 2.
Router 1 (PE1)
-> configure service customer 100 create
-> configure service vpls 100 customer 100 create
-> configure service vpls 100 mesh-sdp 8 create
-> configure service vpls 100 mesh-sdp 8 no shutdown
-> configure service vpls 100 no shutdown
Router 3 (PE2)
-> configure service customer 100 create
-> configure service vpls 100 customer 100 create
-> configure service vpls 100 mesh-sdp 8 create
-> configure service vpls 100 mesh-sdp 8 no shutdown
-> configure service vpls 100 no shutdown
On both PE1 and PE2, the above commands create a customer account with ID 100, create a VPLS servi-
cee with ID 100, and bind the service to SDP 8.
•
A pseudo wire (also referred to as VC) is setup between the far-end VPLS instances.
•
A VC label is associated with the VPLS instance. This is the inner MPLS label that will be carried
from the egress port of the tunnel initiation to the ingress port of the tunnel termination (PE1 to PE2).
•
Since the service is bound to the SDP 8, VPLS service 100 will use the tunnel created in Step 3. In this
case, the tunnel label is 21 (Outer label).
Step 5: Configure the SAPs
Configure a SAP on Router 1 and Router 3 that will map customer traffic with VLAN ID 100 to VPLS
service 100. A SAP is comprised of an access (customer-facing) port, an encapsulation mode/value (for
example, dot1q/vlan id), and a binding with a VPLS service.
Router 1 (PE1)
Configure port 1/1 as an access port (by default all ports are of type network):
-> configure service port 1/1 mode access
