IP connectivity and OSPF

[Ian Dewar]

I would like to know your thoughts on this lab.

IP connectivity and OSPF are preconfigured on all devices where necessary. Do not make any changes to the IP addressing or OSPF. The company policy uses connected interfaces and next hops when configuring static routes except for load balancing or redundancy without floating static. Connectivity must be established between subnet 172.20.20.128/25 on the Internet and the LAN at 192.168.0.0/24 connected to SW1:

1. Configure reachability to the switch SW1 LAN subnet in router R2.
2. Configure default reachability to the Internet subnet in router R1.
3. Configure a single static route in router R2 to reach to the Internet subnet considering both redundant links between routers R1 and R2. A default route is NOT allowed in router R2.
4. Configure a static route in router R1 toward the switch SW1 LAN subnet where the primary link must be through Ethernet0/1, and the backup link must be through Ethernet0/2 using a floating route. Use the minimal administrative distance value when required.

Hi

1. Configure reachability to the switch SW1 LAN subnet in router R2.

conf t

int E0/0

ip add 192.168.0.2 255.255.255.0

2. Configure default reachability to the Internet subnet in router R1.

ip route 0.0.0.0 0.0.0.0 10.10.13.3

3. Configure a single static route in router R2 to reach to the Internet subnet considering both redundant links between routers R1 and R2. A default route is NOT allowed in router R2.

ip route 172.20.20.128 255.255.255.128 10.10.12.129

ip route 172.20.20.128 255.255.255.128 10.10.12.1 2

4. Configure a static route in router R1 toward the switch SW1 LAN subnet where the primary link must be through Ethernet0/1, and the backup link must be through Ethernet0/2 using a floating route. Use the minimal administrative distance value when required.

ip route 192.168.0.0 255.255.255.0 10.10.12.130

ip route 192.168.0.0 255.255.255.0  10.10.12.2 2

Configure a single static route in router R2 to reach to the Internet subnet considering both redundant links between routers R1 and R2. A default route is NOT allowed in router R2.

trick here in this point 

you need to config default-route in R1 or R3 and push this default route via OSPF from R1/R3 to R2 via 
default-information originate under R1/R3

@3. Configure a single static route in router R2 to reach to the Internet subnet considering both redundant links between routers R1 and R2. A default route is NOT allowed in router R2.

if you add @R2# ip route 172.20.20.128 255.255.255.128 10.10.13.3 
this matches all the give requirements. i assume the OSPF is delivering 10.10.13 subnet. 
Company policy statement also provides a hint in this regard.
