Cisco VPLS Configuration

cisco-vpls-configuration-example-ipcisco

In this lesson, we will configure VPLS on Nokia Service Routers. Before any Service configuration, our IGP configuration must be done and the network must be converged. We had talked about this preparations in the previous articles. In this article, we will focus on VPLS configuration. We assume that, our IGP configuration is done and the network converged without any problem. You can also check Cisco VPLS Configuration lesson.

Our example topology will be like below:

Here, first of all, I would like to recall a point, configuring SDPs.Because this point can be complex in the first time. Before VPLS configuration our SDPs also must be configured. As an example you can check the below configuration, that must be done before VPLS configuration. In other words, our SDPs are ready to use.


SDP Configuration on PE Routers

PE1# configure service
PE1# config>service# sdp 20 mpls create
PE1# config>service>sdp$ far-end 2.2.2.2
PE1# config>service>sdp$ lsp “to_routerPE2”
PE1# config>service>sdp$ no shutdown
PE1# config>service>sdp# exit
PE1# config>service# sdp 30 mpls create
PE1# config>service>sdp$ far-end 3.3.3.3
PE1# config>service>sdp$ lsp “to_routerPE3”
PE1# config>service>sdp$ no shutdown
PE1# config>service>sdp$ exit

For bidirectional traffic, the remote side of this SDPs must be configured also. Remember, SDP is unidirectional. One more recall is, SDPs use remote system address as far-end.

PE2# configure service
PE2# config>service# sdp 10 mpls create
PE2# config>service>sdp$ far-end 1.1.1.1
PE2# config>service>sdp$ lsp “to_routerPE1”
PE2# config>service>sdp$ no shutdown
PE2# config>service>sdp$ exit
PE2# config>service# sdp 30 mpls create
PE2# config>service>sdp$ far-end 3.3.3.3
PE2# config>service>sdp$ lsp “to_routerPE3”
PE2# config>service>sdp$ no shutdown
PE2# config>service>sdp>exit

PE3# configure service
PE3# config>service# sdp 10 mpls create
PE3# config>service>sdp$ far-end 1.1.1.1
PE3# config>service>sdp$ lsp “to_routerPE1”
PE3# config>service>sdp$ no shutdown
PE3# config>service>sdp>exit
PE3# config>service# sdp 20 mpls create
PE3# config>service>sdp$ far-end 2.2.2.2
PE3# config>service>sdp$ lsp “to_routerPE2”
PE3# config>service>sdp$ no shutdown
PE3# config>service>sdp>exit

Let’s start to configure VPLS, according to the example topology.


Service Configuration Steps on PE Routers

1.Create Customer.

PE1# configure service
PE1>config>service# customer 100 create
PE1>config>service>cust$ description “Our VPLS Customer 1”
PE1>config>service>cust# exit
PE1>config>service# customer 200 create
PE1>config>service>cust$ description “Our VPLS Customer 2”
PE1>config>service>cust# exit all

v

2.Create VPLS Service associated with Customer ID.

PE1# configure service vpls 110 customer 100 create
PE1>config>service>vpls$ description “VPLS Service of Customer 100”
PE1>config>service>vpls$ exit all
PE1# configure service vpls 120 customer 200 create
PE1>config>service>vpls$ description “VPLS Service of Customer 200”
PE1>config>service>vpls$ exit all


3.Bind SDPs to the VPLS Service.

Here we will bind our predefined SDPs to the services. For each service, we need to reach each customer site. So we will use the predefined two SDPs.

    thank you please I need more tutorial on ccna sp

    Hi Gokhan, Very useful blog on VPLS. Just one feedback, it would be better if you can show required interfaces in GNS3 topology for clarification.

      Thank you very much Sandeep ;) In the following days GNS3 will be added more…Keep on;)
