Chapter Review Questions

  1. You have configured RIP between three routers connected in a serial chain, but no RIP routes are being learned. Which policy results in full RIP connectivity for all direct routes?

    1. A RIP import policy of the form:

      term 1 {
          from protocol [ rip direct ];
          then accept;
      }
    2. A RIP export policy of the form:

      term 1 {
          from protocol [ rip direct ];
          then accept;
      }
    3. A RIP import policy of the form:

      term 1 {
          from protocol direct;
          then accept;
      }
    4. A RIP export policy of the form:

      term 1 {
          from protocol direct;
          then accept;
      }
  2. What happens when the static route 192.168.10/24 is evaluated by this policy?

    [edit policy-options policy-statement test]
    lab@RUM# show
    term 1 {
        from {
            protocol rip;
            route-filter 192.168.0.0/16 orlonger reject;
            route-filter 192.168.10.0/24 exact {
                metric 10;
                accept;
            }
        }
    }
    1. Nothing, because no match occurs

    2. The route is longest-matched against the first route filter and rejected

    3. The route is longest-matched against the second route filter and has its metric set to 10

    4. Both B and C

  3. What type of import policy can you apply to OSPF?

    1. None; LS protocols do not support the notion of import policies because the policy breaks database consistency

    2. You can apply policy to filter certain LSA types, such as AS externals, to create a stub area

    3. Import policy for OSPF can be used only to filter AS external LSAs from being flooded

    4. Import policy for OSPF can be used to prevent installation of AS external routes into the RT, but has no effect on flooding

  4. What is the default action of the test ...
