The correct command to define an aggregate route for 172.30/16 at the [edit routing-options] level of the hierarchy in a Juniper router is:
C. set route aggregate 172.30/16
Explanation: An aggregate route is a summarized route that represents a group of specific routes in the routing table. It helps to reduce the size of the routing table and optimize the routing process.
In Juniper routers, the command to configure an aggregate route is "set route aggregate". The command takes the network prefix and subnet mask or prefix length as an argument. In this case, the network prefix is 172.30 and the subnet mask is /16.
Option A ("set summary route 172.30/16") is not correct because the correct command to configure an aggregate route is "set route aggregate", not "set summary route".
Option B ("set aggregate route 172.30/16") is not correct because the correct syntax is "set route aggregate", not "set aggregate route".
Option D ("set route summary 172.30/16") is not correct because the correct syntax is "set route aggregate", not "set route summary".
Therefore, the correct command to configure an aggregate route for 172.30/16 at the [edit routing-options] level of the hierarchy in a Juniper router is "set route aggregate 172.30/16".
