E-Line VPWS and E-LAN VPLS



Last week I wrote about Metro Ethernet Services like E-Line, E-LAN, E-Tree and E-Access. These are the services that Metro Ethernet Forum (MEF) has defined as CE 2.0 to standardize the services that Carrier Ethernet Providers offer to their customers. This is the way to understand easily the broad service portfolio of service providers to know as customers what we can buy and what we can expect from them.

This time I have been making labs to know how we can configure this kind of services. For that, I have installed GNS3 with Cisco 7200 and CSR1000v routers in a Ubuntu virtual machine. Next, we can see two videos where I have configured an E-Line service and an E-LAN service.

E-Line - MPLS L2VPN InterAS VPWS - EoMPLS Port Mode

In the first lab we are going to configure a Virtual Private Wire Service (VPWS) between two Autonomous Systems (ASN 11111 and ASN 22222). For this configuration all routers are c7200.

Next we can see the video for this service:


E-LAN – Basic VPLS

In the second lab we are going to configure a Virtual Private LAN Service (VPLS) where I have used a CSR1000v router to make the VPLS configuration because this service isn't supported by c7200 router. However, all other routers can be c7200 routers. Once the VPLS configuration is done we can enable EIGRP in CE routers to test that CE routers are in the same LAN and they can be neighbors.

Next we can see the video for this service:


Although these two services may seem the same, it is not the same because the first one is like a point to point link while the second lab is like a switch with multipoint to multipoint links.

Regards my friend and remember, drop me a line with the first thing you are thinking.
