Hello!
If your are refering to this command: match ip route-source prefix-list prefix-list-name you can not use it in your plataform because the command is only avaible in plataforms with this minimum release: 5.0(3)N1(1), and the Nexus 4000 is not compatible.
You can use that command to redistribute routes learned by anothers devices especified in the prefix-list.
