VxLAN Layer 2 support for LVTEP

This section details the support for a logical VxLAN tunnel end point (LVTEP) at Layer 2.

Section contents:

LVTEP control plane
In a BGP EVPN deployment, each node in an LVTEP pair is an independent BGP speaker.
LVTEP data plane
This section presents the details of the LVTEP data plane, including a basic topology, packet formats, and support for various deployment scenarios.
Port-based VLAN bundle service
Multiple customer VLANs can be bundled in a single EVI instance.
Configuring VxLAN LVTEP support
This task configures VxLAN LVTEP support, which includes loopback, VLAN, Ethernet, and bridge domain (BD), overlay gateway, and MCT cluster configurations.
LVTEP support for other features
This section details how LVTEP supports other features.
Nondefault TPID
The Tag Protocol Identifier (TPID) is a 16-bit field that identifies the frame as an IEEE 802.1Q-tagged frame. The TPID is set to the default value of 0x8100, but the user can change this value.
Configuring TCAM profiles to support LVTEP
LVTEP configurations use the vxlan-visibility TCAM profile, as illustrated in this task.
LVTEP show commands
The following show commands are helpful in diagnosing a variety of LVTEP configurations.
