same vlan on two different interfaces

Is it possible to have same vlan number on two different interfaces of same machine?

Yes it is.

Look for bridge

I'm afraid this is both unrelated to VLANs and irrelevant to Solaris.

When I posted it, I saw it was a solaris problem they do always things in their own strange way. And did not know you can not use bridges for VLANs or did you mean you can not use bridges on solaris like in linux. Sorry for the misunderstanding.

No, that's the other way around

The web page you link to doesn't relate to VLANs (but WLANs which are quite different beasts) and the OP question doesn't refer to bridges.

Ok in this case you would be talking of Multipathing VLANs. Like here.

or not ...

Let's wait for jagdip to come back here and better explain his requirements if my positive answer doesn't suit them.

Thank you. My network engineer gave me two different network isolated from each other but have same VLAN number. I was wondering if my solaris server get confused with same VLAN number when routing traffic.

VLAN and networks are at different layers. VLAN is at the Ethernet level (layer 2) while networks are at the IP level (layer 3).
You certainly can configure disconnected networks to share the same VLAN. A server only uses the IP information to route traffic.
