In an previous post Advertising IPs In EVPN Route Type 2, I described use cases for advertising IP addresses in EVPN route type 2. Host ARP and host mobility I already covered so today we will focus on host routing.
VXLAN/EVPN – Host mobility
In the previous post VXLAN/EVPN – Host ARP, I talked about how knowing the MAC/IP of endpoints allows for ARP suppression. In this post we’ll take a look at host mobility. The topology used is the same as in the
VXLAN/EVPN – Host ARP
In the last post Advertising IPs In EVPN Route Type 2, I described how to get IPs advertised in EVPN route type 2, but why do we need it? There are three main scenarios where having the MAC/IP mapping is
Advertising IPs In EVPN Route Type 2
In my last post EVPN Deepdive Route Types 2 and 3, we took a deepdive into these two route types. I mentioned that the IP address of a host, a /32 or /128 address, could optionally be advertised. I also
EVPN Deepdive Route Types 2 and 3
In my last post on Configuring EVPN, we setup EVPN but configured no services. In this post we will configure a basic L2 service so we can dive into the different EVPN route types. This post will cover route type
Configuring EVPN on NX-OS
In this post we will configure EVPN on NX-OS. We will reuse the VXLAN topology from my previous post. The following will describe the setup in this post: The BGP topology is shown below: I will cover all the details
Introduction to EVPN In VXLAN Networks
In previous posts I described VXLAN using flood and learn behavior using multicast or ingress replication. The drawback to flood and learn is that frames need to be flooded/replicated for the VTEPs to learn of each other and for learning
Forwarding BUM Frames in VXLAN Network With Static Ingress Replication
In the last post we used multicast to forward BUM frames. In this post, static ingress replication is used which removes the requirement for multicast in the underlay. Before setting this up, let’s do a comparison of multicast vs ingress
Forwarding BUM Frames in VXLAN Network With Multicast in Underlay
There are two main methods that can be used to forward broadcast, unknown unicast, and multicast (BUM) frames in a VXLAN network: In this post, we take a detailed look at how multicast can be used to forward BUM frames
Choosing the Underlay Protocol in a VXLAN Network
When building a VXLAN network, what are the considerations for choosing the underlay protocol such as OSPF, IS-IS, or BGP? You obviously want the design to be supported by your vendor of choice. Your staff should also be able to
