Basic VPLS Architecture, Full Mesh

Comparison of VPLS and h-VPLS VPLS (Virtual Private LAN Service) and h-VPLS (Hierarhical VPLS) has some common and different properties. So they have different aadvantages and disadvantages.In this article, we will focus on the comparison of these two concepts. The most important different between VPLS and h-VPLS is in the interface between the CE (Customer […]

VPLS (Virtual Private LAN Service) – Part 3 (h-VPLS)

Posted by gokhankosem on 08 Sep 16 - Comments Off on VPLS (Virtual Private LAN Service) – Part 3 (h-VPLS)

H-VPLS (Hierarchical VPLS) H-VPLS (Hierarchical VPLS) is the more scalable version of VPLS. Basically, H-VPLS has some architectural difference than flat VPLS. VPLS Architecture, Flat VPLS In H-VPLS, there are some additional edge devices. These devices are u-PE (User facing Provider Edge) and n-PE (Network facing Provider Edge). By using two different Edge Devices, H-VPLS […]

How LLDP Works, LLDP Mechanism

LLDP (Link Layer Discovery Protocol) LLDP (Link Layer Discovery Protocol) is a Standard Neighbour Discovery Protocol that is used by all vendors. Like all other Neighbour Discovery Protocols, LLDP works on Layer 2 (Data-link Layer). By using LLDP, directly connected neighbours are discovered. To discover a neighbour device, LLDP must be enabled both on the […]

redundancy protocols VRRP (Virtual Router Redundancy Protocol), protocols for redundancy

VRRP(Virtual Router Redundancy Protocol) VRRP(Virtual Router Redundancy Protocol) is a standard based redundancy protocol. The configuration of this protocol is like HSRP with only small differences. In VRRP the active router is called Master, and the remainning ones are all Backup routers. So there can be multiple backup routers. VRRP (Virtual Router Redundancy Protocol) By […]

network redundancy, protocols for redundancy

Network Redundancy Protocols Redundancy is a common point for today’s topologies. Especially in mission-critical networks it is not acceptible that using only one gateway to reach a point. Because one gateway means single point of failure. With multiple gateways, you can still reach the remote node even if the gateway that you connect fails. As […]
