A whole advisor to realizing, designing, and deploying Layer 2 VPN applied sciences and pseudowire emulation applications
- Evaluate marketplace drivers for Layer 2 VPNs
- Understand the architectural frame-work and offerings for Layer 2 VPNs, together with AToM and L2TPv3
- Grasp the necessities of Layer 2 LAN and WAN applied sciences
- Examine the theoretical and operational information of MPLS and LDP as they pertain to AToM
- Understand the theoretical and operational info of Layer 2 protocols over L2TPv3 in IP networks
- Learn approximately Layer 2 VPN bridged and routed interworking and Layer 2 neighborhood switching
- Understand the operation and alertness of digital inner most LAN providers (VPLS)
- Learn approximately origin and complicated AToM and L2TPv3 subject matters via an intensive number of case studies
The historic disconnect among legacy Layer 2 and Layer three VPN recommendations has compelled carrier prone to construct, function, and keep separate infrastructures to house a number of VPN entry applied sciences. This high priced proposition, although, isn't any longer worthy. As a part of its new Unified VPN Suite, Cisco structures® now bargains next-generation Layer 2 VPN companies like Layer 2 Tunneling Protocol model three (L2TPv3) and Any delivery over MPLS (AToM) that let carrier services to provide body Relay, ATM, Ethernet, and leased-line companies over a standard IP/MPLS center community. by means of unifying a number of community layers and delivering an built-in set of software program prone and administration instruments over this infrastructure, the Cisco® Layer 2 VPN answer allows demonstrated companies, IP-oriented ISP/CLECs, and big firm shoppers (LECs) to arrive a broader set of power VPN shoppers and provide actually worldwide VPNs.
Layer 2 VPN Architectures is a complete consultant to consolidating community infrastructures and lengthening VPN providers. The booklet opens via discussing Layer 2 VPN functions using either AToM and L2TPv3 protocols and evaluating Layer three as opposed to Layer 2 provider-provisioned VPNs. as well as describing the suggestions on the topic of Layer 2 VPNs, this ebook presents an in depth choice of case stories that convey you the way those applied sciences and architectures paintings. The case reports comprise either AToM and L2TPv3 and display real-world merchant and firm layout difficulties and suggestions with hands-on configuration examples and implementation info. The case reports contain all Layer 2 applied sciences transported utilizing AToM and L2TPv3 pseudowires, together with Ethernet, Ethernet VLAN, HDLC, PPP, body Relay, ATM AAL5 and ATM cells, and complicated subject matters proper to Layer 2 VPN deployment, similar to QoS and scalability.
