I think it is because you have the same route distinguisher 8298:200 on
all these routers. If i understand it correctly, each router should use
different RD (while they use the same route target (RT) if they are in
the same VPN). We use RD to derive internal distinguisher for ethernet
routes in etab, so if your EVPN routers use the same RD, even that IMET
routes are distinguished in evpntab by other info (router IP), they are
treated as an update to one network after translation to etab.
