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

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]

Exit the port view

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

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

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]

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=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
