Saku,
Jericho is in no sense a low end chip, while there are some scale limitatio=
ns (what can be done with SuperFEC, some bridging related stuff), from funct=
ionality prospective it is a very capable silicon.
One has to:
Understand how to program it properly (recursiveness, ECMP=E2=80=99s, etc)=20
Know how to enhance SDK
Have a rather rich control plane, which can be translated into rich forward=
ing functionality :-)
I=E2=80=99m not familiar with Arista=E2=80=99s feature set
NCS with XR would be a good proof=20
Watch for Jericho updates from DNX
Cheers,
Jeff=20
