EIGRP Feasible Successor
One of the advantages of EIGRP Feasible Successor is that it speeds up the EIGRP. In fact, if there is a Feasible Successor in the EIGRP network, such network converges faster than OSPF or IS-IS.
- But what is EIGRP Feasible Successor and how can we find EIGRP Feasible Successor?
- If there is EIGRP Feasible Successor, how does EIGRP converges faster than OSPF or ISIS?
In this post, I will explain the answers to the above questions.
EIGRP Feasible Successor is a backup node that can satisfy the EIGRP feasibility condition.
Feasibility condition simply means that the backup router should be loop-free.
Let’s examine the topology shown below (Figure-1) to understand how EIGRP finds loop-free alternate/backup node.
Figure-1 EIGRP Feasibility Condition
From the Router A’s point of view, Router B and Router C are the equal cost routers; as a result, both ABD and ACD path can be used in the network. What’s more, Router A installs both Router B and Router C not only in the EIGRP topology table but also in the routing table.
There is no backup router in the above topology since Router A uses both Router B and Router C to reach the destination Continue reading

Heavy Networking 487: Fortinet And The Secure SD-WAN (Sponsored)
Fortinet sponsors today's Heavy Networking podcast. You probably know Fortinet as a firewall company, but today's conversation focuses on Fortinet's secure SD-WAN capabilities. Fortinet guests Nirav Shah, senior director of products and solutions; and Alex Samonte, director of technical architecture come on the podcast to talk about key SD-WAN features, how SD-WAN is evolving, the role of SD-WAN in cloud access, and more.

Five Key Takeaways from the Summit in Asia-Pacific on Deploying, Sustaining and Scaling Community Networks
Community networks (CNs) offer a solution to connect the unconnected billions. They are becoming all the more important as recent trends reveal a slowdown in Internet connectivity growth through national operators in the Asia-Pacific region.
Late August, the Internet Society and the United Nations Economic and Social Commission for Asia and the Pacific organized the Asia-Pacific Regional CN Summit 2019 in Bangkok, Thailand. The event brought together about 110 participants that included high-level government officials from Asia and the Pacific, and a multidisciplinary group of regional experts on community networks, civil society groups, industry representatives, and academics and researchers to deliberate on critical issues surrounding CNs.
What are Community Networks?
They are “do-it-yourself” networks built by people for people. They are not just connecting communities, but are empowering rural and remote communities to improve their lives. Speakers and participants at the Summit shared some successful examples from the region, including India’s Garm Marg Rural Broadband Project, which has improved communities’ access to government and financial services, Nepal’s community networks, which have helped communities recover from the devastating Gorkha Earthquake in 2015 and prepare for future disasters, and Pakistan’s community network, which has enhanced learning for girls at a remote Continue reading

NSX Service Mesh on VMware Tanzu: CONNECT & PROTECT Applications Across Your Kubernetes Clusters and Clouds
Authors: Mark Schweighardt, Tom Spoonemore
Modern enterprises are sprawling and complicated. They are transitioning from private to public clouds to address, for example, performance, availability, and data residency requirements, and to gain access to advanced services such as analytics and ML. They are also transforming their application architectures from monoliths to distributed microservices.
In August 2019, VMware introduced VMware Tanzu, a new portfolio of products and services to transform the way enterprises BUILD modern applications on Kubernetes, consistently RUN Kubernetes across clouds, and MANAGE Kubernetes fleets from a single control point. This is a huge win for our customers: Using Tanzu Mission Control to consistently create and manage the lifecycle of Kubernetes clusters across any cloud.
But how do we consistently connect and secure traffic between the services distributed across all of these clusters and clouds, while delivering on application SLAs? Today we further develop this picture by introducing NSX Service Mesh on VMware Tanzu. NSX Service Mesh provides an application connectivity and security fabric that can span across all of your Kubernetes clusters and cloud environments. NSX Service Mesh allows you to:
- CONNECT – Intelligently control and observe traffic and Continue reading
