Use the ip param instead. Deprecated VPC private IP Address Name of the routing table(s), where the route for the IP address should be changed. If declaring multiple routing tables they should be separated by comma. Example: rtb-XXXXXXXX,rtb-YYYYYYYYY routing table name(s) Role to use to query/update the route table route table query/update role Name of the network interface, i.e. eth0 network interface name You can specify an additional label for your IP address here. This label is appended to your interface name.
