VPWS – Distributed Epipe Configuration

Distributed Epipe Configuration

In the previous Epipe Example, we have talked about “Local Epipe Configuration“. So, we have used only one device and our Epipe service was in this device. Here, we will use two router and we will show the “VPWS Distributed Epipe Configuration“. This configuration is widely used VPWS Epipe Service.

 

For this VPWS Distributed Epipe Configration, we will use the below topology. As you can see, here, we will use two routers and one more term, SDP (Service Distribution Point).

Here, the first configuration steps of VPWS Distributed Epipe is the same as before. We will create service and link it to a customer. We will un shutdown the service. We will add SAPs at the two end. Here, we will add one more thing, SDP configuration.

 

Firstly, let’s create Epipe Service and link it to a Customer.

 

Nokia-Router-1 # config
Nokia-Router-1>config# service
Nokia-Router-1>config>service# epipe 20
Nokia-Router-1>config>service>epipe# customer 3 create
Nokia-Router-1>config>service>epipe# description “Epipe-to-Router-2”
Nokia-Router-1>config>service>epipe# no shutdown

 

Now, let’s create SAP under the Epipe Service.

 

Nokia-Router-1>config>service>epipe# sap 1/1/1 create
Nokia-Router-1>config>service>epipe>sap # no shutdown
Nokia-Router-1>config>service>epipe>sap # exit

 

Now, the different part is came. We will configure SDP. SDP is showed like below:

 

SDP-ID : VC-ID

Here, SDP-ID is local to the router. It can be any value. But, VC-ID must be same on both routers.

Nokia-Router-1>config>service # epipe 20 customer 3
Nokia-Router-1>config>service>epipe# spoke-sdp 10:100
Nokia-Router-1>config>service>epipe>spoke-sdp# no shutdown
Nokia-Router-1>config>service>epipe>spoke-sdp# exit
Nokia-Router-1>config>service>epipe# no shutdown

 

Now, let’s configure Epipe Service on the second router.

 

Nokia-Router-2 # config
Nokia-Router-2>config# service
Nokia-Router-2>config>service# epipe 20
Nokia-Router-2>config>service>epipe# customer 3 create
Nokia-Router-2>config>service>epipe# description “epipe to Router-1”
Nokia-Router-2>config>service>epipe# no shutdown

Nokia-Router-2 > config > service > epipe# sap 1/1/1 create
Nokia-Router-2 > config > service > epipe> sap # no shutdown
Nokia-Router-2 > config > service > epipe> sap # exit

Nokia-Router-2 > config > service # epipe 20 customer 3
Nokia-Router-2 > config > service > epipe# spoke-sdp 30:100
Nokia-Router-2 > config > service > epipe>spoke-sdp# no shutdown
Nokia-Router-2 > config > service > epipe>spoke-sdp# exit
Nokia-Router-2 > config > service > epipe# no shutdown

 


 

Distributed Epipe Verification

To verify VPWS services, we can use many commands on Nokia 7750 SR Routers. These commands are given below:

  • Show service customer
  • Show service id [base | all | labels | sdp [detail]]
  • Show service service-using
  • Show service sap-using
  • Show service sdp-using
  • Show service sdp [detail]
  • Show router ldp bindings

Epipe for Multiple Customer and Service per SAP

In a SAP, we can define one more Services, also one more Epipe service. To do this, we need to change the encapsulation type of the SAP port. This encapsulation type must be “dot1q”.

This is done like below:

Nokia-Router-1>config # port 1/1/1
Nokia-Router-1>config>port # ethernet encap-type dot1q
Nokia-Router-1>config>port # exit

After that, in the same SAP, different customers and services can be used with sub interfaces like SAP 1/1/1.10, 1/1/1.11 etc.


 

Applying SAP Parameters

 

Under the SAPs, we can add additional filters, policies,qos etc. to these interfaces. We can add these under SAP through ingress or egress.
