**To create a prefix list**
The following ``create-managed-prefix-list`` example creates an IPv4 prefix list with a maximum of 10 entries, and creates 2 entries in the prefix list. ::
aws ec2 create-managed-prefix-list \
--address-family IPv4 \
--max-entries 10 \
--entries Cidr=10.0.0.0/16,Description=vpc-a Cidr=10.2.0.0/16,Description=vpc-b \
--prefix-list-name vpc-cidrs
Output::
