Description
Configure the switch to preserve the original VLAN tag (in the inner Ethernet packet) when performing Virtual Extensible LAN (VXLAN) encapsulation.
Preserving the original VLAN tag is implicit with VLAN bundle services.
As a result, in an EVPN-VXLAN environment, you don't need to
configure this option with EVPN MAC-VRF instance
vlan-bundle
service type configurations.
Explicitly configure this option with other service types if needed.
Starting in Junos OS release 23.2R2, you cannot configure the
encapsulate-inner-vlan
statement in
a MAC-VRF routing instance if the vlan has an IRB interface
associated with it.
Starting in Junos OS release 22.3R1, IS-IS logical link control (LLC) packets that are encapsulated in a VXLAN tunnel now have their VLAN tags removed by default. You can configure this option to preserve the VLAN tags on IS-IS LLC packets.
ARP suppression is automatically disabled when you encapsulate
VLAN traffic for EVPN-VXLAN by configuring
encapsulate-inner-vlan
and its
equivalent converse statement
decapsulate-accept-inner-vlan
. As a
result, you might observe ARP packets being sent by the
device.
Default
When the device encapsulates the packet, it drops the original VLAN tag.
