Specifying a reserved VXLAN for VXLAN IS-IS
For the VTEP to exchange VXLAN IS-IS packets with remote VTEPs, you must specify a reserved VXLAN.
The reserved VXLAN must be the same across the VTEPs.
You can specify only one reserved VXLAN on the VTEP. All VSIs on the VTEP use the reserved VXLAN to
transmit and receive VXLAN IS-IS packets. The reserved VXLAN cannot be a VXLAN created on any VSI.
To specify a reserved VXLAN for VXLAN IS-IS:
Step Command Remarks
1. Enter system view. system-view N/A
2. Specify a VXLAN as the
reserved VXLAN.
reserved vxlan vxlan-id
By default, no VXLAN is specified as the
reserved VXLAN.
Enabling VXLAN autonegotiation to automate
VXLAN tunnel assignment
VXLAN autonegotiation enables the VTEPs to advertise local VXLAN IDs through VXLAN IS-IS. Two VTEPs
automatically assign the VXLAN tunnel between them to a VXLAN if both of them have the VXLAN ID.
To automate VXLAN tunnel assignment:
Step Command Remarks
1. Enter system view. system-view N/A
