• Question 577:

  Lab Simulation - MLS and EIGRP

  You have been tasked with configuring multilayer SwitchC, which has a partial configuration and has been attached to RouterC as shown in the topology diagram.

  You need to configure SwitchC so that Hosts H1 and H2 can successfully ping the server S1.

  Also SwitchC needs to be able to ping server S1.Due to administrative restrictions and requirements you should not add/delete vlans or createtrunk links. Company policies forbid the use of static or default routing. All routes must be learned

  via EIGRP 650 routing protocol.

  You do not have access to RouteC. RouterC is correctly configured. No trunking has been configured on RouterC. Routed interfaces should use the lowest host on a subnet when possible. The following subnets are available to implement this

  solution:

  A. Check the answer below

  A. Check the answer below

  In real life, there are two ways to configure interVLAN routing in this case:

  + Use RouterC as a "router on a stick" and SwitchC as a pure Layer2 switch. Trunking must be established between RouterC and SwitchC. + Only use SwitchC for interVLAN routing without using RouterC, SwitchC should be configured as a Layer 3 switch (which supports ip routing function as a router). No trunking requires.

  The question clearly states "No trunking has been configured on RouterC" so RouterC does not contribute to interVLAN routing of hosts H1 and H2 -> SwitchC must be configured as a Layer 3 switch with SVIs for interVLAN routing.

  We should check the default gateways on H1 and H2. Click on H1 and H2 and type the "ipconfig" command to get their default gateways.

  C:\>ipconfig

  We will get the default gateways as follows:

  Host1:

  +

  Default gateway: 190.200.250.33 Host2:

  +

  Default gateway: 190.200.250.65
