Optimized VXLAN Replication using Underlay
Multicast
ExtremeXOS 31.2 provides support for Virtual Extensible Local Area Network (VXLAN)
underlay multicast (multicast tunnel). This feature provides support for the
following:
- Dynamic virtual networks.
- BUD node operation (a VTEP acting as both transit and tunnel terminating
node).
- MLAG.
- OSPF/BGP underlay and EVPN.
- Ability to configure VXLAN multicast tunnels in existing VXLAN deployments.
- Spine node can be a non-VTEP in leaf-spine topologies.
- Bandwidth preservation through optimized replication.
- Flexible choice of Multicast Distribution Tree (MDT).
- Option for automatic group address assignment for each VNI.
Supported Platforms
ExtremeSwitching X670-G2, X870, X690, X590, X695, X465 series switches.
Limitations
This feature has the following limitations:
- Supported only for overlay
BUM traffic.
- Supported only with
PIM-SSM.
- BUD node operation is not supported with MLAG.
- Multicast group range used for this feature cannot be configured/used for
regular multicast traffic.
Note
This feature should not be used with Assisted Replication.
