[bess] GW-based Proxy ARP/ND Solution with EVPN UMR & Inter-DC Mobility

[Joshi, Vinayak]

Hi all,

Is it correct to say that GW-based Proxy ARP/ND Solution 
(https://www.ietf.org/archive/id/draft-sajassi-bess-evpn-umr-mobility-03.html#name-gw-based-proxy-arp-nd-solut)
 should not deployed when inter-DC mobility of end hosts is possible?
This is because even if the GW maintains mobility sequence number per network 
(local/interconnects) it does not advertise MAC/IP routes into the local DC (DC 
1 in the draft) in this solution.
Hence, it doesn’t help PEs in DC1 to recognize MAC move to DC2.

Regards,
Vinayak
