In this post, we look at why SD-Access borders have the anycast IP addresses configured as loopback addresses.
In this post, we look at various DHCP challenges in Cisco’s SD-Access fabric and how it is solved.
In this post, we look at multi-instance LISP, which is another core construct for Cisco’s SD-Access.
In this post, we look at an actual LISP host mobility event and what happens behind the scenes to make this work.
In this post, we look at SMRs and how these are essential for a host mobility event, within the LISP architecture.
In this post, we look at LISP dynamic EID - a core construct of LISP host mobility.
In this post, we look at how a LISP site talks to non-LISP sites.
In this post, we introduce basic LISP configuration and operation using packet captures and packet walks.
This is a new series that will cover Cisco’s Software Defined Access architecture/solution over time. There are several moving pieces to this - in this post, we’re going to start with a key component, which is LISP.
In this post, we take a look at the interaction of MLAG with an EVPN based VXLAN fabric on Cumulus Linux.

In this post, we introduce BGP EVPN and a VXLAN fabric in Cumulus Linux, with L2VNIs.
In this post, we’ll look at BGP unnumbered on Cumulus Linux.
In this post, we introduce BGP on Cumulus Linux.
In this post, we will look at an introduction to routing on Cumulus Linux, with static routing and OSPF.
This second blog on Cumulus looks at basic layer2 functionality in Cumulus Linux.
This first blog on Cumulus introduces the reader to the basics of the operating system and Cumulus' NCLU.
