What is the primary difference between the commands ip route and ipv6 route?

• A. ip route configures IPv4 routes; ipv6 route configures IPv6 routes
• B. ip route configures routes for both IPv4 and IPv6
• C. ip route is dynamic, ipv6 route is static
• D. ip route is used only for incoming, ipv6 route for outgoing

Answer: (A)

IPv4 and IPv6 are separate address families, so routing configurations are kept in separate contexts. The ip route command creates static routes for IPv4 destinations, while the ipv6 route command creates static routes for IPv6 destinations. They’re targeted at different protocol stacks, so one cannot configure the other. You can have both on the same router, but they belong to different routing tables. The other options mix up how these commands work: one doesn't cover both families, and the distinction isn’t about dynamic versus static or about the direction of traffic.
