After running the script, you should see that the data interfaces have the appropriate IP addresses assigned, as per the tables for [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb1#IPAddressAssignment SB1] and [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb2#IPAddressAssignment SB2].
