Thanks Han for the explanation. Yes, there is no east-west traffic between the GRs (I was just curious to know). So, if the ARP request/response between GR and DR is confined to the same chassis, then there shouldn't be O(n^2) explosion per-your explanation. Will get back to you on how the test

Hello Han, Can you please explain how the dynamic resolution of the IP-to-MAC will work with this new option set? Say the packet is being forwarded from router2 towards the distributed router? So, nexthop (reg0) is set to IP1 and we need to find the MAC address M1 to set eth.dst to.

So we can get rid of the join logical switch. This might be a dumb question, but why do we need an external switch? In the local gateway mode: pod--logical switchDR---join switch (to remove) --- GR 169.x.x.2---external switch---169.x.x.1 Linux host There's no reason in the above to have
