L2TP is often used by ISPs when internet service over for example ADSL or cable is being resold. From the end user, packets travel over a wholesale network service provider's network to a server called a Broadband Remote Access Server ( BRAS ), a protocol converter and router combined.
The data modeling language can be used to model both configuration data as well as state data of network elements. Furthermore, YANG can be used to define the format of event notifications emitted by network elements and it allows data modelers to define the signature of remote procedure calls that can be invoked on network elements via the ...
Logical View of a Layer 2 MPLS VPN. A Layer 2 MPLS VPN is a term in computer networking.It is a method that Internet service providers use to segregate their network for their customers, to allow them to transmit data over an IP network.
MPLS VPN is a family of methods for using Multiprotocol Label Switching (MPLS) to create virtual private networks (VPNs). MPLS VPN is a flexible method to transport and route several types of network traffic using an MPLS backbone.
Example of BUM in PBB-EVPN in the case of Dual home device and all-active load-balancing. Ethernet VPN (EVPN) and Provider Backbone Bridging EVPN (PBB-EVPN) provide Ethernet multipoint services over MPLS networks. In EVPN operations, the Provider Edge (PE) routers automatically discover each other when connected on the same Ethernet segment and ...
Generic routing encapsulation (GRE) is a tunneling protocol developed by Cisco Systems that can encapsulate a wide variety of network layer protocols inside virtual point-to-point links or point-to-multipoint links over an Internet Protocol network.
Virtual Private LAN Service (VPLS) is a way to provide Ethernet-based multipoint to multipoint communication over IP or MPLS networks. It allows geographically dispersed sites to share an Ethernet broadcast domain by connecting sites through pseudowires.
The customer edge router (CE) generally refers to the router at the customer premises that is interconnected with the provider edge router of a service provider's IP/MPLS network.
