Route Redistribution – A thing of the past?

July 2, 2013 at 11:21 am PST

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).

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.

Blogging Journey from Cisco Live from Cisco ONE: Intelligent Programmable Network

Cisco Live is here! It’s a great opportunity for you to discover some really exciting technology solutions at our Cisco ONE: Cisco Intelligent Programmable Network booth featuring a few of our latest innovations.

Onsite you will be able to see and ask your questions at live demos featuring applications and services developed with One Programmable Kit (onePK), Openflow and the eXtensible Network Controller. In addition, we have demos devoted to IPv6, routing, service discovery and network design simulation -- all things meant to make your network simpler and smarter.

There are also some great partner demos including our friends from SAP, Citrix, Glue Networks, Pramacom, Radware, and Starview who are showing some really cool apps that use the Cisco ONE APIs. Read More »

Cisco Opens Up EIGRP

What’s new and exciting with EIGRP (Enhanced Interior Gateway Routing Protocol)? Actually, lots…  First a bit a background on EIGRP.

EIGRP is an advanced distance vector routing protocol used extensively by enterprise customers.  It is very popular because it is simple to deploy and support. Some major attributes are:

  • EIGRP does not mandate many network design requirements and is therefore perceived as “forgiving” and “flexible”.  For example, EIGRP does not require support for multiple routing sub-domains or Areas.
  • While route summarization is a recommended best practice to minimize route table size, it is optional with EIGRP.
  • EIGRP can scale to support thousands of routers in a Hub and Spoke configuration.  The Hub and Spoke design is especially popular in WAN networks.

For additional information on EIGRP, please click here.  There is also a great BLOG that compares EIGRP and OSPF that I think you will find informative and is posted here.

While EIGRP has a large customer following, some customers have hesitated because of concerns of EIGRP being “proprietary”, which would prevent them from multi-vendor network support.  In some cases this has caused customers to design their networks to limit usage of EIGRP, even though they would like to deploy it ubiquitously.  One result has been non-optimal network design and traffic flow, resulting from multiple IGP (Interior Gateway Protocol) redistribution points.

That brings me back to what is new and exciting with EIGRP. Read More »
