Epipe Configuration

In the previous part we have talked about the VPWS service of Alcatel-Lucent. In this article we will focus on the configuration of the VPWS Service on Alcatel-Lucent devices.

As you know, there are types of VPWS. Epipe, Fpipe, Apipe, Cpipe and Ipipe are these types. The most important and widely used is Epipe service. So, here, we will start with Epipe service configuration.

Epipe service is the Point-to-Point Ethernet L2 VPN Service between two Service Routers as we have talked before. Ethernet is a widely used technology, so with ethernet, VPWS Epipe service become widely used beside other types.

As Other Alcatel-Lucent VPN Services, in VPWS the service configuration has some basic steps. In this configuration lesson, we will focus on these configuration steps, and we will show Epipe VPN Service configuration steps one by one.

Alcatel-Lucent VPWS Service Logic

For Epipe VPN Configuration we will create the service with service ID firstly. In the same command, we will also create a customer and link VPN service to this customer.Then, we will define SAPs and SDPs.

Here, one point is important. If we are configuring a Local Epipe, an Epipe that is used on the same device, we will need to configure multiple SAPs and there is no need for SDP configuration.

If we are configuring a Distributed Service that need multiple device, then we need to configure also an SDP beside SAP or SAPs.

Aftet this two important terms, the last configuration step is “enabling the service”. We will enable our Epipe VPN Service.

Now, let’s configure two examples topoogy for Epipe VPN Service.

Here, we will configure a Local Epipe Service first and then we will configure a Distributed Epipe Service.

Required Configurations Before Epipe Configuration

Alcatel-Lucent Epipe Service configuration needs some pre configuratiions as all the other Service configurations. What are these preconfigurations? These preparation steps are given below:

• Build the IP (GRE) or IP/MPLS core network.
• Configure Routing Protocols (OSPF,ISIS etc.)
• Configure MPLS LSPs (if MPLS is used).
• SDPs must be created.
• Accounting Policies, Schedular Policies, QoS Policies and Filters must be configured .

These steps and pre configurations are required in all Service Provider networks that provide VPN Services. This is also required for Epipe VPN Service.

Local Epipe Service Configuration

For Local Epipe Service Configuration, we will use the below topology. This is a basic router not a topology exactly. Because, Local Service Configuration is done in the same device.


local-epipe-configuration

The first step is creating Epipe VPN Service with Service-ID. In the same command we will create a customer and link this service to the customer.

Alcatel-Router-1# config
Alcatel-Router-1>config# service
Alcatel-Router-1>config>service# epipe 10
Alcatel-Router-1>config>service>epipe# customer 2 create

Under the service, we will also configure a description. And we must “no shutdown” the service.

Alcatel-Router-1>config>service>epipe# description “Local-Epipe”
Alcatel-Router-1>config>service>epipe# no shutdown

Now, we will configure the SAPs under this Service. We have service configuration but there is nobody to send and receive on this service. We will configure these end points, SAPs.

Here, we will also define the encapsulation type firstly. Encapsuation is configured with “ethernet encap-type {dot1q|null|qinq}” command. For one customer and one service per port, we will configure this port encapsulation as null.

Alcatel-Router-1>config# port 1/1/1
Alcatel-Router-1>config>port# ethernet encap-type null
Alcatel-Router-1>config>port# exit

Alcatel-Router-1>config# service epipe 10
Alcatel-Router-1>config>service>epipe# sap 1/1/1 create
Alcatel-Router-1>config>service>epipe>sap# no shutdown
Alcatel-Router-1>config>service>epipe>sap# exit
Alcatel-Router-1>config>service>epipe# sap 1/1/2 create
Alcatel-Router-1>config>service>epipe>sap# no shutdown
Alcatel-Router-1>config>service>epipe>sap# exit

To verify our configuration, we can check the service configuration by “info” command under the service.

Alcatel-Router-1>config>service# info
———————————————-
Epipe 10 customer 2 create
description ” Local-Epipe ”
sap 1/1/1:0 create
exit
sap 1/1/2:0 create
exit
no shutdown
exit

In the second example, we will show the other service verification commands one by one.

For the second Epipe example, Ditributed Epipe Configuration, you can continue with the other parts.

Gokhan,
Thanks for the example. It make sense to me. I recently joined a new company which has a number of cell backhaul sites. When looking at the configs of the equipment I noticed that our folks do this a little different than you. We use Alcatel-Lucent gear. They create a customer facing SAP and link it via an epipe to the local uplink port. Another SAP on that port connect to and SDP to the PE router. My question is why create the internal epipe? Your opinion please?

hello,

Have you got a way of setting up a GRE tunnel between a 7750 and a Cisco router? If so,is it possible to paste your configs of both vendor’s routers?

Hi Gokhan,

My question is like from Ty

Is it possible to set up a GRE tunnel between a 7750 and a Cisco router or between 7750 and 7750 on network interface without service? For example the network in PE1(7750)-P(7750)-PE2(7750). How to set up gre tunnel between PE1 and PE2? Is it possible?

Hi Gokhan,

How can we create multiple vlan service over epipe??

Thanks,

HiGokhan,
My name is Yong-ki Park
i am korean. so i can not to English very well.
this web site is very cool.
i trying this lab.
but i can not this config.
==================================
*A:SR-01>config>service# epipe 1 customer 5 create
MINOR: SVCMGR #1101 Invalid customer-id
*A:SR-01>config>service#
==================================
how to set customer id ?
i want to set customer id (2 ~ 2147483647)
just i can customer id 1. but i want other number

i using SR-C4, SAR-8, SAS-M

please help me.

If I had a cisco mpls network
What are the equivalent commands

To alcatel 7210.
For example I build service
Epipe
Sap
Sdp

How do I create this on
Let’s say a piece of Cisco equipment
