Figure 6 VPLS service in each ISP between PE and P routers with SAP connections to CE routers
Part 1: Provider Edge Router Configuration (R5-R8)
1) Create the VPLS service.

XXX#>configure service vpls 1 customer 1 create µ!
XXX#>config>service>vpls$ no shutdown µ!
2) SDPs are used to distribute services across multiple service routers, and therefore,
bind a transport tunnel to the service. You will need to create a mesh-sdp between
each PE router (R5-R8) to allow full communication across the PE routers. Each PE
router should have 3 mesh-SDPs at the conclusion of this step. Note that a mesh-sdp
will not forward a frame out another mesh-sdp, allowing for a loop free service
topology within the core.
XXX#>configure service vpls 1 mesh-sdp x create µ!
XXX#>config>service>vpls>mesh-sdp$ back µ!
Where x is the sdp # to the other PE routers. (R5=5, R6=6. R7=7, R8=8)
3) Service Access Points are used to attach CE devices to services on PE devices.
XXX#>configure service vpls 1 sap X/Y/Z create µ!
Where X/Y/Z is the physical port connecting the CE device to the PE
a. Were you successful at adding the SAP? _______

Part2: Verification
NOTE: Wait till your peer nodes are also at this step before proceeding.
a. View the in-use Service LDP bindings on the P and PE routers. (U after label
indicates in-use)
XXX# show router ldp bindings fec-type services. µ!

b. Network Connectivity:

b. Are you able to ping the other CE devices in the lab? _____
c. Are you able to ping the system IP address of the P device from the CE
device? ____
d. Explain the results?

c. Services: Use the following command to determine the health of your services.
XXX#> show service service-using µ!
a. How many services are there on each device in your POD? ______
b. What is their status? ______
c. Use the following command to find out more information about your service:
XXX#> show service id 1 base µ!
d. On each PE device, we can see the MAC database per service using the
following command.
XXX#> show service id 1 fdb detail µ!
i. How many local MAC addresses are in your table? ____
ii. How many remote MAC addresses are in your table? ____
e. On the PE devices (R5-R8), shutdown the SDP to the PE device in the
clockwise direction from you.
XXX#>configure service sdp x shutdown µ!
Where x is the SDP to the remote PE device (R5=5, R6=6, R7=7, R8=8)
i. How many OSPF adjacencies are there on your CE device? _____
ii. Ping the system IP addresses of all other CE devices in the lab.
