SwitchC(config-if)#  ip address 10.0.250. But in the exam the sim is just a flash based simulator so we should use two above commands.200.33 Host2: + Default gateway: 190. • Packets from devices in the subnet of 172. in fact it is not necessary because the network 190.200.40. Click on H1 and H2 and type the “ipconfig” command to get their default gateways.65 Now we have enough information to configure SwitchC (notice the EIGRP AS in this case is 650) Note: VLAN2 and VLAN3 were created and gi0/10.200.120. • Filtering should be implemented as close to the serverfarm as possible.Correct Answer: Answer: There are two ways to configure interVLAN routing in this case: Section: Layer 2 Technologies Explanation Explanation/Reference: + Use RouterC as a “router on a stick” and SwitchC as a pure Layer2 switch.120. The topology diagram indicates their layer 2 mapping.200.250.120.250. just for sure. even without “no auto-summary” command the network still works correctly.0/24 should be allowed on VLAN 20.

SwitchC should be configured as a Layer 3 switch (which supports ip routing function as a router).0″ because it is the nature of distance vector routing protocol like EIGRP: only major networks need to be advertised.0. Trunking must be established between RouterC and SwitchC. + Only use SwitchC for interVLAN routing without using RouterC.31″ we can use one simple command “network 190. For security reasons.10.64 0. and from the PCs as well. We should check the default gateways on H1 & H2.0.255.0.0. Also make sure you use the correct EIGRP AS number (in the configuration above it is 650 but it will change when you take the exam) but we are not allowed to access RouterC so the only way to find out the EIGRP AS is to look at the exhibit above.250.0 is shown. No trunking requires. the simulator does not let you assign IP address on Gi0/1 interface. you should expect the ping to SERVER to succeed from the MLS. no neighbor relationship is formed between RouterC and SwitchC. If you use wrong AS number.0.255.200.0  ->RouterC has used IP 10. • Devices on VLAN 20 are restricted to the subnet of 172.com is an IT company that has an existing enterprise network comprised of two layer 2 only switches.0.250.200.0. so you will not miss within it in the exam. only the summarized network 190.200.

QUESTION 157 SWITCH. The question clearly states “No trunking has been configured on RouterC” so RouterC does not contribute to interVLAN routing of hosts H1 & H2 -> SwitchC must be configured as a Layer 3 switch with SVIs for interVLAN routing.32 0.
