Hi,

Hardware is really nice.
Backplane, buffers, just basically =E2=80=9Cpumping=E2=80=9D bandwidth. =
It=E2=80=99s really good.

However, mlag can show some bugs when having only 1 interface in an MLAG =
(only 1 side) they had issues with the ifindex numbering in software.
There were OSPF configuration options missing, etc.

In short, hardware is really nice, software needs more maturing.=20
Nice for distribution but not for core.
