Inter-Vlan Routing in Alcatel-Lucent Switch

[yasirsattar06]

Hello Everyone,

I am new in ALU Data. I have worked on Alcatel Voice products and Cisco Voice & Data products.
I have one OmniSwitch 6860E-P24 for testing and Lab environment.
I configured different Vlans and now i need to make communication between different Vlans on same switch. What shall i make configiration?

[silvio]

it should be the same as at other L3-switches (like cisco). You need ip interfaces in both vlans at the switch. And than you have to use this ip addresses as gateway in your hosts (one host in one vlan/network - and the other host in other vlan/network).

Hi Silvio,

In Cisco, i apply the configurations like this for L3:

vlan 10
interface f 1/0
switchport access vlan 10

interface vlan 10
ip address 10.1.1.1 255.0.0.0

vlan 20
interface f 2/0
switchport access vlan 20

interface vlan 20
ip address 10.1.2.1 255.0.0.0


Still these two vlans are unable to communicate, Now to make communication between these vlans, i'll give this command:
>ip routing

Now in Alcatel 6860E:

vlan 10
vlan 10 members port 1/1/1
ip interface vlan-10 address 10.1.1.1 mask 255.255.255.0 vlan 10

vlan 20
vlan 20 members port 1/1/2
ip interface vlan-20 address 10.1.2.1 mask 255.255.255.0 vlan 20

Now will these two vlans will communicate?
What will be the commands equivalent to <ip routing> (in cisco) for communication of vlan 10 and 20?

There is no equivalent. Alcatel does l3forwarding by default
Aren't you missing an untagged at the vlan xx members statement?

And I would think everything should work with this commands ( btw you got net masks for Cisco wrong -would not work this way )

Hi

vlan 10
vlan 10 members port 1/1/1 untagged
ip interface vlan-10 address 10.1.1.1 mask 255.255.255.0 vlan 10

vlan 20
vlan 20 members port 1/1/2 untagged
ip interface vlan-20 address 10.1.2.1 mask 255.255.255.0 vlan 20

you can check with
show ip interfaces

Is the forwarding (=routing) are active?
per default this will, if the vlan is up.

Hi Silvio,

Thanks for your kind response.

I have made same configurations and checked with "show ip interface", but PC1 is still unable to access PC2.

PC1 Settings are:
IP: 10.1.1.10
SM: 255.255.255.0
GW: 10.1.1.1

PC2 Settings are:
IP: 10.1.2.10
SM: 255.255.255.0
GW: 10.1.2.1

I have attached the status of ip interfaces. Please check.

Hi,
than routing will works...

Check the mac-table and arp-table if your clients in correct vlan (show mac-learning, show arp).
Disable firewall at your clients. Disable all other interfaces (wlan etc.) at your clients.

Dear Silvio,

Thanks for your support.
Issue resolved. There was firewall issue on Clients PCs.

Kind Regards,
