vlan vlan-id-list
By default, only the system default VLAN (VLAN 1) exists.
Configuring a super VLAN
1. Enter system view.
system-view
2. Enter VLAN view.
vlan vlan-id
3. Configure the VLAN as a super VLAN.
supervlan
By default, a VLAN is not a super VLAN.
4. Associate the super VLAN with the sub-VLANs.
subvlan vlan-id-list
Make sure the sub-VLANs already exist before associating them with a super VLAN.
Configuring a super VLAN interface
Restrictions and guidelines
As a best practice, do not configure VRRP for a super VLAN interface because the configuration
affects network performance. For more information about VRRP, see High Availability Configuration
Guide.
Procedure
1. Enter system view.
system-view
2. Create a VLAN interface and enter its view.
interface vlan-interface interface-number
The value for the interface-number argument must be the super VLAN ID.
3. Configure an IP address for the super VLAN interface.
IPv4:
ip address ip-address { mask-length | mask } [ sub ]
IPv6:
ipv6 address { ipv6-address prefix-length | ipv6-address/prefix-length }
By default, no IP address is configured for a VLAN interface.
4. Configure Layer 3 communication between sub-VLANs by enabling local proxy ARP or ND.
IPv4:
local-proxy-arp enable
By default:
{ Sub-VLANs cannot communicate with each other at Layer 3.
{ Local proxy ARP is disabled.
For more information about local proxy ARP, see Layer 3—IP Services Configuration Guide.
IPv6:
local-proxy-nd enable
By default:
