Linux Kernel VxLan with Multicast Routing for Flood Handling

Explore a comprehensive conference talk on Linux Kernel VxLan with Multicast Routing for flood handling. Delve into the two methods of handling flooded traffic to multiple remote VxLan termination end points (VTEPs), focusing on the preferred multicast routing approach. Examine the current challenges in integrating VxLan Multicast replication within dynamic multicast routing environments, particularly in data center CLOS networks with Top-Of-the-Rack (TOR) switch deployments. Discover proposed solutions, including patches for routing locally generated multicast packets and modifications to the VxLan driver. Gain insights into deployment scenarios, scalability considerations, and future prospects for VxLan in multicast environments. Learn about the complexities of configuring outgoing interfaces for VxLan multicast replication and the role of multicast routing protocols like PIM in dynamically calculating multicast trees and installing forwarding paths.
