Multiple choice

An administrator is configuring a dual stack router with IPv6 and IPv4 using RIPng. The administrator receives an error message when trying to enter the IPv4 routes into RIPng. What is the cause of the problem?

  1. When IPv4 and IPv6 are configured on the same interface, all IPv4 addresses are over-written in favour of the newer technology.

  2. Incorrect IPv4 addresses are entered on the router interfaces.

  3. RIPng is incompatible with dual-stack technology.

  4. IPv4 is incompatible with RIPng.

D Correct answer
Explanation

RIPng (RIP next generation) is designed exclusively for IPv6 networks. IPv4 routing uses RIPv1 or RIPv2, which are completely separate protocols. You cannot mix IPv4 routes with RIPng configuration as they operate on different IP stacks.
