Guidelines

-

This is a lab item in which tasks will be performed on virtual devices.

• Refer to the Tasks tab to view the tasks for this lab item.

• Refer to the Topology tab to access the device console(s) and perform the tasks.

• Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window.

• All necessary preconfigurations have been applied.

• Do not change the enable password or hostname for any device.

• Save your configurations to NVRAM before moving to the next item.

• Click Next at the bottom of the screen to submit this lab and move to the next question.

• When Next is clicked, the lab doses and cannot be reopened.

Topology

Tasks

-

Refer to the topology. All physical cabling is in place. Routers R3 and R4 are fully configured and inaccessible. Configure static routes for various connectivity to the ISP and the LAN, which

resides on R4.

1. Configure a default route on R2 to the ISP

2. Configure a default route on R1 to the ISP

3. Configure R2 with a route to the Server at 10.0.41.10

4. Configure R1 with a route to the LAN that prefers R3 as the primary path to the LAN

Anyone knows how best to practice this simulation questions? Because it is harder to replicate the whole configuration of the question because some configs have already been done. So how can I practice these simulations?

How can you have two different command for the same question? Shouldn’t R1&R2 have the same default IP route configuration to ISP?

nothanksimgucci

Assume that no routing protocol is running within the network, R1 therefore has no way of knowing how to reach 209.165.200.224/27 as it sees only its local, connected routes on its E0/0 and E0/1 interfaces. Should you therefore add a default route of 0.0.0.0 0.0.0.0 209.165.200.225 on R1, it's just going to drop the packets as 209.165.200.225 isn't in its routing table, which is why you instead route traffic destined for unknown addresses on R1 to the next hop of R2's IP on the E0/0 interface in the 10.0.12.0/30 network. R2 will know what to do with the traffic since you already gave R2 the default route to the ISP in Task 1.

The given answer is correct

Correct me if I'm wrong R1: ! ! en conf t ip route 0.0.0.0 0.0.0.0 10.0.12.2 ip route 10.0.41.0 255.255.255.0 10.0.13.3 ip route 10.0.41.0 255.255.255.0 10.0.12.2 2 do wr R2: ! ! en conf t ip route 0.0.0.0 0.0.0.0 209.165.200.225 ip route 10.0.41.10 255.255.255.255 10.0.24.4 do wr

The default route to the isp in R1 should be ip route 0.0.0.0 0.0.0.0 209.165.200.225

JunsK1e

I will stick in my configuration, because you can apply the ip route with the destination of isp. but you cannot ping from r1 to isp

flipq123

there's configuration in r2 routed to ISP, if the packet send to r1 was not at the routing table of r1 so it will route it to the default gateway of the r1, so it is ok to configure in r1 as ip route 0.0.0.0 0.0.0.0 e0/0 or nex hop ip addres.

Where did you even get 10.0.13.3?
