OTV or I could use L2TPv3 with pseudo wire or

Hi Experts,

While study for my lab, Id like some help on a high end scenario. I have 2
datacentres and I want to connect their LAN at layer 2 between both
datacentres. Each data centre has a ASA firewall.
 1) How can I extand the layer 2 network from datacentre 1 to
datacentre 2 without spanning-tree loops. I was planning on using either
Cisco's new protocol *OTV* or I could use *L2TPv3 pseudo wire*.
*QinQ*trunks or I could just create a
*port-channel* across the 2 datacentres and trunk the interfaces
2) How can I ensure that the stateful NAT entries are the same on both
firewalls?
Any help or suggestions on best practice of how to do this would be
appreciated.
