200-301 Exam Question 431

All physical cabling is in place. Router R4 and PCI are fully configured and inaccessible. R4's WAN interfaces use .4 in the last octet for each subnet.
Configurations should ensure that connectivity is established end-to-end.
1 . Configure static routing to ensure RI prefers the path through R2 to reach only PCI on R4's LAN
2. Configure static routing that ensures traffic sourced from RI will take an alternate path through R3 to PCI in the event of an outage along the primary path
3. Configure default routes on RI and R3 to the Internet using the least number of hops Guidelines This is a lab item in which tasks will be performed on virtual devices.

Correct Answer:

See the solution below in Explanation.
Explanation:
* To configure static routing on R1 to ensure that it prefers the path through R2 to reach only PC1 on R4' s LAN, you need to create a static route for the host 10.0.0.100/8 with a next-hop address of 20.0.0.2, which is the IP address of R2's interface connected to R1. You also need to assign a lower administrative distance (AD) to this route than the default AD of 1 for static routes, so that it has a higher preference over other possible routes. For example, you can use an AD of 10 for this route. To create this static route, you need to enter the following commands on R1's console:
R1#configure terminal R1(config)#ip route 10.0.0.100 255.0.0.0 20.0.0.2 10 R1(config)#end
* To configure static routing on R1 that ensures that traffic sourced from R1 will take an alternate path through R3 to PC1 in the event of an outage along the primary path, you need to create another static route for the host 10.0.0.100/8 with a next-hop address of 40.0.0.2, which is the IP address of R3's interface connected to R1. You also need to assign a higher AD to this route than the AD of the primary route, so that it has a lower preference and acts as a backup route. For example, you can use an AD of
20 for this route. This type of static route is also known as a floating static route. To create this static route, you need to enter the following commands on R1's console:
R1#configure terminal R1(config)#ip route 10.0.0.100 255.0.0.0 40.0.0.2 20 R1(config)#end
* To configure default routes on R1 and R3 to the Internet using the least number of hops, you need to create a static route for the network 0.0.0.0/0 with a next-hop address of the ISP's interface connected to each router respectively. A default route is a special type of static route that matches any destination address and is used when no other specific route is available. The ISP's interface connected to R1 has an IP address of 10.0.0.4, and the ISP's interface connected to R3 has an IP address of 50.0.0.4. To create these default routes, you need to enter the following commands on each router's console:
On R1: R1#configure terminal R1(config)#ip route 0.0.0.0 0.0.0.0 10.0.0.4 R1(config)#end On R3: R3#configure terminal R3(config)#ip route 0.0.0.0 0.0.0.0 50.0.0.4 R3(config)#end
