Distributed Epipe Service 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 “Distributed Epipe Configuration”. This configuration is widely used VPWS Epipe Service. For Distributed […]

GRE (Generic Routing Encapsulation) GRE Overview GRE (Generic Routing Encapsulation) is the mechanism that encapsulate one protocol in another protocol and provides connection between the nodes. This is done basically IP over IP. A Service Provider Network or Internet is used for GRE (Generic Routing Encapsulation). GRE provides this communication over a Tunnel.This is called […]

VPLS Labelling (Tunnel and Service Labels) As we discussed in the MPLS articles before, for MPLS we need labels. VPLS is also a MPLS Service, so we need to use labels in VPLS too. There are two MPLS labels used in VPLS. These labels are: • Outher Label (Transport Label) • Inner Label (Servise Label […]

VPLS MAC Learning VPLS is a Leyer 2 VPN technology. Becuase of its Layer 2 nature, “MAC Learning” is very important for VPLS. So, how does VPLS learn MAC Addresses? MAC Learning in VPLS is similar to normal switching MAC Learning. The concept is basic. At the beginning nobody knows the others. So, to send […]

vpls-topologies-hierarchical-

VPLS Topologies VPLS can be defined on One Service Router or on Multiple Service Routers. Basically we can divide VPLS into two here. The first one is VPLS, that is defined on one Service Router of Service Provider, by using router ports only. As Alcatel-Lucent (Nokia) translation, this type of VPLS is done only by […]
