Vlan aggregation is a feature that prevents the
waste of IP addresses and implements inter-vlan
communication in enterprise network environment.
Using vlan aggregation, you need to configure IP
address only in super-vlan interface, without having
to assign IP addresses for each of the sub-vlans: all
sub-vlans share the same IP network-segment.
In our example we will assume a simple
configuration scenario: on an enterprise network, we
have different departments belonging to different
vlans; employees in different departments need to
communicate with ech other. As shown in the picture,
the super-vlan will be VLAN 10 and the sub-vlans
will be VLAN 5 and VLAN 7. The PC’s IP addresses
are in the same IP network segment and are shown
in the table.
PC1 PC2 PC3 PC4
PC1 IP address: 100.1.1.2/24
PC2 IP address: 100.1.1.3/24
PC3 IP address: 100.1.1.4/24
PC4 IP address: 100.1.1.5/24

3. ADDING INTERFACES OF THE SWITCH TO
SUB-VLANS (1)
1. Set the interface type
Enter the configuration view
Enter the port view
Configure the port type
<Huawei> system-view
[Huawei] interface gigabitethernet 0/0/1
[Huawei-GigabitEthernet0/0/1] port link-type access
[Huawei-GigabitEthernet0/0/1] quit
[Huawei] interface gigabitethernet 0/0/2
[Huawei-GigabitEthernet0/0/2] port link-type access
[Huawei-GigabitEthernet0/0/2] quit
[Huawei] interface gigabitethernet 0/0/3
[Huawei-GigabitEthernet0/0/3] port link-type access
[Huawei-GigabitEthernet0/0/3] quit
[Huawei] interface gigabitethernet 0/0/4
[Huawei-GigabitEthernet0/0/4] port link-type access
[Huawei-GigabitEthernet0/0/4] quit
[Huawei]
Exit the port view

4. ADDING INTERFACES OF THE SWITCH TO
SUB-VLANS (2)
[Huawei] vlan 7
[Huawei-vlan7] port GigabitEthernet 0/0/1 0/0/2
[Huawei-vlan7] quit
[Huawei] vlan 5
[Huawei-vlan5] port GigabitEthernet 0/0/3 0/0/4
[Huawei-vlan5] quit
[Huawei]
2. Configure vlan 7 and vlan 5
Create and enter the vlan view
Add physical ports to vlan
Exit the vlan view

5. ADDING THE SUB-VLANS TO A SUPER-
VLAN
3. Configure the super-vlan
[Huawei] vlan 10
[Huawei-vlan10] aggregate-vlan
[Huawei-vlan10] access-vlan 5 7
[Huawei-vlan10] quit
Enter the vlan view
Configure the vlan as a super-vlan
Add the sub-vlans to the super-vlan
Exit the vlan view

6. CONFIGURING THE IP-ADDRESS FOR THE
SUPER-VLAN
4. Configure the vlanif interface for the super-vlan
Enter the vlanif view
Configure the ip address for the vlanif
Exit the vlanif view
[Huawei] interface vlanif 10
[Huawei-Vlanif10] ip address 100.1.1.1 24
[Huawei-Vlanif10] quit
[Huawei]

7. CONFIGURING PROXY ARP FOR THE
SUPER-VLAN
[Huawei] interface vlanif 10
[Huawei-Vlanif10] arp-proxy inter-sub-vlan-proxy enable
[Huawei-Vlanif10] quit
5. Configure proxy arp
6. Verify the configuration (vlan 5 is reachable from vlan 7)
PC1> ping 100.1.1.4
Ping 100.1.1.4: 32 data bytes, Press Ctrl_C to break
From 100.1.1.4: bytes=32 seq=1 ttl=127 time=16 ms
From 100.1.1.4: bytes=32 seq=2 ttl=127 time<1 ms
From 100.1.1.4: bytes=32 seq=3 ttl=127 time<1 ms
From 100.1.1.4: bytes=32 seq=4 ttl=127 time<1 ms
From 100.1.1.4: bytes=32 seq=5 ttl=127 time=31 ms
--- 100.1.1.4 ping statistics ---
5 packet(s) transmitted
5 packet(s) received
0.00% packet loss
round-trip min/avg/max = 0/9/31 ms
Enter the vlanif view
Enable the proxy arp
Exit the vlanif view
