LAG or MSTP

I have two Dell 6248 switches and want to know if I need to use MSTP if I have two connections between them or if I can use LAG. I have several VLANS and am hoping to use a LAG instead. I want the fail over that LAG offers, but am not sure if I need MSTP because of the two connections and multiple VLANS.

Thanks

from_expCommented:
lag performs as ordinal interface from stp point of view.
you can be save to configure lag and use standard (rapid) stp.

I would prefer mstp in case of looped topology and with multiple vlans, where I desire to have all loop nodes functioning (in this case you configure first mstp domain to go clock wise and the second one - anti clock wise), because normal stp will block redundant physical link, not redundant vlan connection.

However, again, lag is normal interface from the stp point of view.
