Simplifying Multi-Provider WAN Designs

This week, at Cisco Live Orlando, we are introducing a brand new EIGRP feature called Over-the-Top (OTP). EIGRP OTP is focused on simplifying the deployment of branch networks utilizing an EIGRP end-to-end solution over public and private networks. This simplicity is further enhanced with EIGRP use of Over-the-Top (OTP) to support multiple service provider IP networks.

Connecting sites over a WAN cloud can be complex, especially when supporting thousands of branch locations, multiple service providers, and feature requirements like encryption. Aside from the configuration challenges, operationally, customers need to filter routes while avoiding routing loops during redistribution, which makes it harder to troubleshoot the network.

The EIGRP Over-the-Top (OTP) solution simplifies multi-provider IP WAN network designs. It simplifies the interface with the WAN providers and facilitates an end-to-end EIGRP network, which is easier to troubleshoot.

Hitchhiker’s Guide for Service Providers at Cisco Live Orlando

Cisco Live at Orlando in 2013 offers a host of opportunities if you are a service provider or a large enterprise that offers services to internal groups. Watch out for the following five key areas and the respective speaking sessions when it comes to software capabilities of the Routing & Switching platforms—(1) IPv6, (2) SDN, (3) Core IP & Optical, (4) Ethernet Access & Aggregation and (5) IP Routing.


June 2012 officially marked the IPv6 Internet with the World IPv6 Launch led by the Internet Society. Within the first six months, IPv6 traffic broke the 1% threshold and established the fact that IPv6 had moved from an experiment to mainstream phase with US traffic approaching close to 3%. Join us for a discussion on where IPv6 is headed (Session ID: PSOSPG-1330) — new opportunities for IPv6 with Internet of Everything. We will be delighted to share our experiences deploying IPv6 (Session ID: PNLCRS-2303) as our IPv6 gurus highlight deployment best practices and real-world challenges. For those of you in Networking, we got you covered with the Troubleshooting IPv6 session (Session ID: BRKRST-2304).

E-VPN and PBB-EVPN Take Data Center Interconnect to the Next Level

Tina-lamBy Tina Lam, Product Manager

MPLS based Layer 2 VPN has been around for over 10 years since the inception of IETF Pseuduowire Edge to Edge (PWE3) Working Group. Many drafts and standards have been added, since then, to address different applications and to improve scale and convergence in different topologies. L2VPN as a whole is widely deployed in both service providers and enterprises, from Ethernet services, to fixed and mobile convergence, to enterprise campus layer-2 transport.

Recently, one emerging driver that has been picking up a lot of momentum is to use L2VPN for Data Center Interconnect (DCI). Data centers are often situated in different locations, to be geo-redundant for the purpose of workload mobility and business continuity. At the same time the physical location of the data center has to be transparent to users and to applications. Hence the need for layer-2 connectivity between sites. While Ethernet over MPLS (EoMPLS) and Virtual Private LAN Service (VPLS) have been used for this purpose, DCI presents new requirements and challenges not fully addressed today.  To keep the data center always on, and to utilize all the resources and links as efficiently as possible, data centers need all-active redundancy and load balancing. The technology should be as simple as possible to provision and manage Read More »

Cisco CPAK Helps Win Best 100G Optical Product


Cisco CPAK 100G LR-4 Transceiver

Although we introduced the Cisco CPAK 100G pluggable transceiver back in March at OFC/NFOEC, many people hadn’t yet seen our CMOS photonics technology from our acquisition of Lightwire back in 2012. As a result we had a lot of interest at the WDM Monaco event this week to learn more about the solution capable of lowering the space, power, and complexity of deploying 100 Gbps interfaces by up to 70%. So much interest in fact that we won the “Best Optical Product – 100G” award!

The March of the IPv6 Internet

gunter_vandeveldeBy Gunter Van de Velde, Sr Technical Leader, NOSTG Engineering

It has been a year since the World IPv6 Launch and in that year the global usage of IPv6 has more than doubled. Where traditionally it is believed that there is no IPv6 traffic on the Internet is now shown differently! The reality of real existing user traffic demonstrates the progress of the next generation of the Internet. During the World IPv6 Launch a year ago there was about 0.64% of Internet traffic carried over IPv6, while right now about 1.35% of the Internet traffic is carried over IPv6. That is nearly double and experts believe exponential growth is expected over the next couple of years.

Another data-point is the readiness of the service providers regarding IPv6. On the Internet there are about 44,470 Autonomous networks announcing one or more IPv6 prefixes into the global routing system. A year ago only about 13.7% of them were announcing IPv6 prefixes. That number increased to 16.1% resulting in 7.168 networks out of the 44.470 that are announcing IPv6 prefixes right now.
