У меня 2 VPC на AWS VPC-A 172.31.0.016 и VPC-B 172.17.0.0/24
Я создал пиринг VPC и могу подключиться ко всем службам, работающим на VPC-B из VPC-A и наоборот.
Теперь я создал фланелевую виртуальную сеть в VPC-B с адресом 172.17.0.0/16
etcdctl set /coreos.com/network/config '{ "Network": "10.17.0.0/16", "Backend": {"Type": "aws-vpc"} }'
В aws-vpc бэкэнд работает, потому что маршруты появились в VPC-B таблица маршрутизации и машины в VPC могут достигать сервисов, размещенных во фланелевой сети, но я не смог связаться с хостами в 172.17.0.0/16 из VPC-A.
VPC-A таблица маршрутизации:
