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
Building a VXLAN Lab Using Nexus9000v
As I dive into the world of VXLAN, I will need a lab as that is the best way to deepen the learning process and to get hands-on experience with a protocol. I will be building a Cisco Nexus9000v lab
Many to Many Multicast – PIM BiDir
Introduction This post will describe PIM Bidir, why it is needed and the design considerations for using PIM BiDir. This post is focused on technology overview and design and will not contain any actual configurations. Multicast Applications Multicast is a
IPv6 Multicast
These are my notes for IPv6 multicast for the CCDE exam. Overview Prefix FF::/8 reserved for multicast Multicast Listener Discovery (MLD) replaces IGMP MLD is part of ICMPv6 MLDv1 equivalent to IGMPv2 MLDv2 equivalent to IGMPv3 ASM, SSM and Bidir
CCDE – Next Generation Multicast – NG-MVPN
MVPNs have been lacking support for MPLS encapsulation. NG-MVPN supports the use of MPLS encapsulation and provides a lot of different profiles. When is a profile suitable and which one should you choose?
HSRP AWARE PIM
In environments that require redundancy towards clients, HSRP will normally be running. HSRP is a proven protocol and it works but how do we handle when we have clients that need multicast? What triggers multicast to converge when the Active
The Tale of the Mysterious PIM Prune
Christmas is lurking around the corner and in the spirit of Denise “Fish” Fishburne, I give you the “The Tale of the Mysterious PIM Prune”. I have been working a lot with multicast lately which is also why I’ve blogged
Using EEM to Speed up Multicast Convergence when Receiver is Dually Connected
When deploying PIM ASM, the Designated Router (DR) role plays a significant part in how PIM ASM works. The DR on a segment is responsible for registering mulicast sources with the Rendezvous Point (RP) and/or sending PIM Joins for the
Lessons Learned from Deploying Multicast
Lately I have been working a lot with multicast, which is fun and challenging! Even if you have a good understanding of multicast unless you work on it a lot there may be some concepts that fall out of memory
INE 10 day bootcamp – Review
I’m back from London and it’s been a great experience. Many readers are interested in what the bootcamp is like. It is a big investment to go for so it is understandable that you want to know if it will
