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
Potential Issues with Multicast within a VLAN Spanning Switches
Background I ran into an interesting issue yesterday at work. There is a new video system being installed, which takes the video output from computers, encodes it and sends it as multicast to a controller. The controller then displays it
More on SSM
As you’ve noticed I’ve been studying SSM and what better way to learn than to blog about it. I recently got a Safari subscription which has been great so far. I’ve been reading some in the book Interdomain Multicast Routing:
Multicast – SSM mapping
This is a followup post to the first one on SSM. The topology is still the same. If you want to find it in the documentation it is found in the IGMP configuration guide I guess the reason to place
Source Specific Multicast (SSM) and IGMP filtering
Regular multicast is known as Any Source Multicast (ASM). It is based on a many to many model where the source can be anyone and only the group is known. For some applications like stock trading exchange this is a
Followup on multicast helper map
I had some requests for the final configs so I have fixed those. You can download them here. Also I had some issues getting the traffic through but thanks to my helpful readers like zumzum I now have it figured
