You can map VLANs to the specific MSTIs rapidly by using the
vlan-mapping modulo
modulo
command. The ID of the MSTI to which a VLAN is mapped can be figured out by using the following
formula:
(VLAN ID-1) %
modulo
+ 1.
In this formula, (VLAN ID-1) %
modulo
yields the module of (VLAN ID-1) with regards to the
modulo
argument. For example, if you set the
modulo
argument to 16, then VLAN 1 is mapped to MSTI 1, VLAN
2 is mapped to MSTI 2, …, VLAN 16 is mapped to MSTI 16, VLAN 17 is mapped to MSTI 1, and so on.

vlan-vpn tunnel
Syntax
vlan-vpn tunnel
undo vlan-vpn tunnel
View
System view
Parameters
None
Description
Use the
vlan-vpn tunnel
command to enable the VLAN-VPN tunnel function for a switch.
Use the
undo vlan-vpn tunnel
command to disable the VLAN-VPN tunnel function.
The VLAN-VPN tunnel function enables BPDUs to be transparently transmitted between geographically
dispersed user networks through specified VLAN VPNs in operator’s networks, through which spanning
trees can be calculated across these user networks and are independent of those of the operator’s
network.
By default, the VLAN-VPN tunnel function is disabled.
