This week at CiscoLive Orlando, Cisco made two announcements around Enterprise Routing -- Open EIGRP and EIGRP OTP. Originally announced at CiscoLive London, EIGRP has been opened to the community as an IETF Informational Draft “Open EIGRP”, Open EIGRP provides vendors with technical information on EIGRP and the accumulation of 20 years of development and enhancements. With the publishing of this IETF Draft, vendors can now integrate EIGRP into their appliances and interop with Cisco.
On Tuesday, Cisco also announced a new innovation in Enterprise Routing; “EIGRP Over the Top” (or simply OTP).

A team of us at Cisco has been working, together with industry colleagues, on defining and standardizing a new Layer 2 VPN solution known as Ethernet Virtual Private Network or E-VPN. In this post, I will discuss the key requirements that helped shape this solution, and attempt to shed some light on the drivers for the technology and how it enables the evolution of Service Provider L2VPN offerings.

Widely deployed from the core to the edge, IP/MPLS has achieved huge success as a mature, standards-based technology now deployed by virtually every service provider worldwide. As a result, the industry has chosen to extend IP/MPLS and develop a transport profile called MPLS-TP (MPLS Transport Profile). MPLS-TP is the packet transport technology of choice being developed by the IETF to allow service providers to cost effectively migrate existing transport networks to packet based solutions.
Recently EANTC conducted an MPLS-TP Interoperability Event which focused on testing and demonstrating interoperability of key IP/MPLS and Carrier Ethernet features between multiple vendor platforms. This represented a critical technology demonstration for service providers as they begin their migration to packet transport networks.

The OSI stack has long served the telecom industry as a model for engineering since the early 80′s (which IMHO was the best decade for music, but I digress). Nowadays the industry is abuzz with a host of developments in the lower layers of the OSI stack. Technologies like OTN and MPLS-TP are being built to extend transport characteristics in the packet domain. At the same time, bandwidth technologies continue to scale upwards to 100G and beyond. While discussions at layer 8 abound on some of them, the industry is largely converging on a standards-based path for development.
Earlier in May, Cisco hosted the IP NGN Virtual Summit where many of you got a flavor of the Transport Architecture evolution amongst various other topics. Following its success, we decided to expand on Transport Technologies in more detail in an hour-long event. The format is much more interactive, and those of you with burning questions can ask them live to our panel of experts. (Register Here)
The event will be held on Tuesday October 5, 2010 with two broadcasts to suit your schedule (each features the live Q&A):
- First Broadcast: 0500-0600 PDT (San Francisco), 1200-1300 GMT (London)
- Second Broadcast: 0900-1000 PDT (San Francisco), 1600-1700 GMT (London)
