We run LACP either to the same or different routers=20
depending on a few internal factors.
=46or LACP to different routers, we use MC-LAG.
Don't want to have to deal with "Spamming" Tree :-).

Same problem on the Huawei, too.
=46ull support is planned for mid-to-late 2013. Of course,=20
that puts a dent in our plans.

We've found that the Huawei works well with other vendor=20
optics too. Cisco, Juniper, OEM's. All good.
Of course, for 10Gbps uplinks, the SFP+ units are bought=20
from Huawei. We have some SPF+ modules from Cisco and their=20
OEM's, but haven't tried them on the Huawei. Experience=20
suggests it would work, but they're quite premium that we=20
always need them for the Cisco's anyway :-).
Mark.
