2. Enter VXLAN IS-IS view. vxlan-isis
By default, the VXLAN IS-IS process is
not created.
The VTEP creates the VXLAN IS-IS
process if it has not been created.
3. Enable VXLAN
autonegotiation.
negotiate-vni enable
By default, VXLAN IS-IS does not
exchange VXLAN IDs.
Enabling MAC advertisement through VXLAN IS-IS
To advertise and receive MAC reachability information through VXLAN IS-IS:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VXLAN IS-IS view. vxlan-isis
By default, the VXLAN IS-IS process is
not created.
3. Enable MAC
advertisement through
VXLAN IS-IS. mac-synchronization enable
IMPORTANT:
You must enable remote-MAC
address learning if MAC
advertisement through VXLAN IS-IS is
enabled.
By default, VXLAN IS-IS does not
advertise or receive MAC reachability
information.
Tuning VXLAN IS-IS parameters
Tune VXLAN IS-IS parameters on a VXLAN or NVE tunnel interface to optimize the protocol performance.
On an NVE tunnel interface, VXLAN IS-IS parameter changes apply to all VXLAN tunnels that are set up
using the NVE tunnel interface.
Setting the VXLAN IS-IS hello interval and the hello multiplier for
calculating the adjacency hold time
VTEPs regularly send VXLAN IS-IS hellos over VXLAN tunnels to establish and maintain adjacencies and
elect a DED on each tunnel. A short interval enables faster network convergence, but it requires more
system resources. A long interval requires fewer system resources, but it delays network convergence.
Adjacency hold time sets the amount of time that the remote VTEPs can retain the adjacency with the
local VTEP before an adjacency update.
• If Graceful Restart is disabled, the adjacency hold time equals the VXLAN IS-IS hello interval
multiplied by the hello multiplier.
• If Graceful Restart is enabled, the adjacency hold time equals the greater value between the
following settings:

The restart interval.
