Hi Hudianto,

It's really going to depend on exactly what type of WAN and the physical distance between the two LANs.

There are multiple ways to extend a Layer 2 domain across a Layer 3 network but your success will depend on the specifics of the individual implementations.

For instance, I have successfully run vPC (Cisco) across dual 10Gbps links between a pair of Cisco Nexus 7010s which were about 30 miles apart. Now I relied on a pair of Ciena 5200 DWDM platforms to provide the 10Gbps links.

Good Luck!

Depends on your needs, you can use e.g. SPB to expand VLAN over WAN.

With SPB T-UNI you can even use a WAN connection completly transperent to your network.
Itīs always the networks fault!
