We run LACP either to the same or different routers 
depending on a few internal factors.

For LACP to different routers, we use MC-LAG.

Don't want to have to deal with "Spamming" Tree :-).

Same problem on the Huawei, too.

Full support is planned for mid-to-late 2013. Of course, 
that puts a dent in our plans.

We've found that the Huawei works well with other vendor 
optics too. Cisco, Juniper, OEM's. All good.

Of course, for 10Gbps uplinks, the SFP+ units are bought 
from Huawei. We have some SPF+ modules from Cisco and their 
OEM's, but haven't tried them on the Huawei. Experience 
suggests it would work, but they're quite premium that we 
always need them for the Cisco's anyway :-).
