Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
ip neigh
Why it's wrong here
ip neigh displays the neighbour (ARP) cache mapping IP addresses to link-layer addresses, not routes. It is tempting because neighbour entries and routing both concern next-hop reachability, but the routing table itself is shown by ip route; neigh answers which MAC owns a given IP on the local segment.
- ✗
ip addr
Why it's wrong here
ip addr lists interface IP address assignments and their state, not the routing table. It is tempting because interface addresses feed into route selection and the output looks network-focused, but routes are displayed by ip route; addr answers which addresses are configured on each interface.
- ✗
ip link
Why it's wrong here
ip link shows layer-2 interface state such as flags, MTU and MAC addresses, not routing entries. It is tempting because link status affects whether routes are usable, but the routing table is displayed by ip route; link answers whether interfaces are up and their hardware addressing.
- ✓
ip route
Why this is correct
The ip route command queries the kernel's routing table via the iproute2 suite, listing destination networks, gateways and interfaces. It satisfies the requirement to display current routes, unlike legacy netstat -r or route, which are deprecated on modern Linux distributions.
