Which command is used to see what the administrative distance to a network is before changing it?

1. show ipv6 eigrp topology

2. show ip route

3. show ipv6 eigrp neighbors

4. show interfaces

The correct answer is: show ip route

The command that displays the administrative distance to a network is indeed the one that shows the routing table and the associated metrics of the routes, which includes administrative distance. When you use the command that provides an overview of the routing table, it reveals various routing protocols, including their associated administrative distances, metrics, and the routes to different networks. This allows a network administrator to assess the current routing configuration before deciding to make changes. The other commands listed do not focus on showing administrative distances directly. One command pertains specifically to EIGRP neighbors and is used to view neighboring routers within that particular protocol. Another command deals with EIGRP topology, presenting specific paths to destinations as determined by EIGRP but lacking direct details about administrative distances. The last command focuses on showing interface status and statistics, which is unrelated to route metrics or administrative distances.
