Description

Enable the vxlan-gbp-mc-profile unified forwarding table (UFT) profile on the tunnel termination endpoint in your EVPN-VXLAN deployment to support multicast traffic flows and group-based policy (GBP) unicast traffic flows together.

GBP makes use of existing Layer 3 (L3) VXLAN network identifiers (VNI) and firewall filter policies to provide micro-segmentation at the device or tag level, independent of the underlying network topology. When you configure this profile, the device allocates shares of its UFT resources for both unicast traffic flows and multicast traffic flows to support GBP unicast traffic seamlessly with enhanced optimized intersubnet multicast (OISM) traffic.

OISM handles multicast traffic efficiently in an EVPN-VXLAN data center for multicast sources and receivers inside and outside the data center. OISM has two modes, regular mode and enhanced mode. We support only enhanced OISM mode with GBP, and only when you configure this GBP UFT profile.

See GBP Profiles for more on GBP profiles and configurations. See Overview of Enhanced OISM for details on how enhanced OISM works. You configure GBP and enhanced OISM together the same way you configure the features separately.

Note:

We don't assign GBP tags to multicast flows. Only unicast traffic carries the GBP tags in the VXLAN headers.

When you configure this profile:

  • On a switch in a Virtual Chassis—You must reboot the switch to apply this setting.

  • On a standalone switch—The packet forwarding engine (PFE) automatically restarts.
