E-LAN services using QinQ-Maipu

In this section, I will share one testing report. This will help you to configure E-LAN services over Maipu Metro Ethernet switch network.

In this scenario, We are using Maipu 3400 switches and enabled QinQ technology in all switches to achieve ELAN and make reachable all connected routers. There is one more way of configuration using evc commands. But I feel this is easy to configure.

So I prefer this way.

Here is topology:

Topology

VLAN200 is used as outer vlan (ISP inside VLAN)in the backbone network. We are using QinQ tunnel technology to achieve ELAN services.

Objective - The requirement is Router-B can communicate with Router-A, Router-C can communicate with Router-A, and Router-B can’t communicate with Router-C.

Configurations:

Switch-A:

hostname SW-A

vlan 1      

 exit

vlan 100

 description ###control_VLAN###

 exit

vlan 200

 description ###outer_tag###

 exit

!slot_0_SM3400-24FET4GEFA

!slot 0

port 0/0

 port-type nni

 port mode trunk

 port trunk allowed vlan all

 port trunk pvid vlan 1

 no spanning-tree enable

 exit

port 0/1

 port-type nni

 port mode trunk

 port trunk allowed vlan all

 port trunk pvid vlan 1

 no spanning-tree enable

 exit

 port hybrid untagged vlan 1,200

 port hybrid pvid vlan 1

 vlan dot1q-tunnel enable

 vlan dot1q-tunnel drop

 vlan dot1q-tunnel 20,30 200

 exit

interface vlan1

 ip address 1.1.1.1 255.255.255.0

 exit

eips ring 1 master segment

 control vlan 100

 instance 0

 secondary port 0/1

 eips start

 exit

 vlan dot1q-tunnel enable

 vlan dot1q-tunnel drop

 vlan dot1q-tunnel 20 200

 exit

 exit

eips ring 1 transit segment

 control vlan 100

 instance 0

 primary port 0/0

 secondary port 0/1

 eips start

 exit

Switch-C:

hostname SW-C

vlan 1      

 exit

vlan 100

 description ###control_VLAN###

 exit

vlan 200

 description ###outer_tag###

 exit

!slot_0_SM3400-24FET4GEFA

!slot 0

port 0/0

 port-type nni

 port mode trunk

 port trunk allowed vlan all

 port trunk pvid vlan 1

 no spanning-tree enable

 exit

port 0/1

 port-type nni

 port mode trunk

 port trunk allowed vlan all

 port trunk pvid vlan 1

 no spanning-tree enable

 exit

port 0/2

 port-type nni

 port mode hybrid

 port hybrid untagged vlan 1,200

 port hybrid pvid vlan 1

 vlan dot1q-tunnel enable

 vlan dot1q-tunnel drop

 vlan dot1q-tunnel 30 200

 exit

interface vlan1

 ip address 1.1.1.3 255.255.255.0

 exit

eips ring 1 transit segment

 control vlan 100

 instance 0

 primary port 0/0

 secondary port 0/1

 eips start

 exit

Router-A:

interface fastethernet0.20

 ip address 20.1.1.1 255.255.255.0

 encapsulation dot1q 20

 exit

interface fastethernet0.30

 ip address 30.1.1.1 255.255.255.0

 encapsulation dot1q 30

 exit

Router-B:

interface fastethernet0.20

 ip address 20.1.1.2 255.255.255.0

 encapsulation dot1q 20

 exit

Router-C:

interface fastethernet0.30

 ip address 30.1.1.2 255.255.255.0

 encapsulation dot1q 30

 exit

Result:

On the router A, router A can ping to router B and router C both

But router B can’t communicate with Router-C because they are in different VLAN:

Check the switch:

Hope this configuration will help you in deployment of ELAN.
