We support IS-IS for multivendor networks. IS-IS logical link control (LLC) packets that are encapsulated in a Virtual Extensible LAN (VXLAN) tunnel now have their VLAN tags removed by default.
If you want the VLAN tags to be preserved and carried through VXLAN tunnels, use the following configuration statement: set routing-instances routing-instance-name vlans vlan-name vxlan encapsulateinner-vlan
