Question

The graphic shows two routers, R1 and ISP, that are connected together on two WAN links.  On the first WAN link, R1 connects to the ISP router through interface S0/0/0 and IP address 192.168.0.33/30, and the ISP router uses interface S0/0/0 and IP address 192.168.0.33/30. On the second WAN link R1 is connects to the ISP router through interface S0/0/1 and IP address 192.168.0.37/30,  and the ISP router uses interface S0/0/1 and IP address 192.168.0.38/30.

Question

The graphic shows two routers, R1 and ISP, that are connected together on a WAN link,  and R1 is connected to a LAN segment. R1 is connected to the Ethernet segment on interface G0/0 with IP address 172.16.0.0/16. R1 is connected to the ISP router through interface S0/0/0 and IP address 209.165.200.224 and the ISP router uses interface S0/0/1 and IP address 209.165.200.224.

Refer to the exhibit. R1 was configured with the static route command ip route 209.165.200.224 255.255.255.224 S0/0/0 and consequently users on network 172.16.0.0/16 are unable to reach resources on the Internet.

Question

The graphic shows two routers, R1 and ISP, that are connected together on two WAN links.  On the first WAN link, R1 connects to the ISP router through interface S0/0/0 and IP address 192.168.0.33/30, and the ISP router uses interface S0/0/0 and IP address 192.168.0.33/30. On the second WAN link R1 is connects to the ISP router through interface S0/0/1 and IP address 192.168.0.37/30,  and the ISP router uses interface S0/0/1 and IP address 192.168.0.38/30. OSPF is running as the routing protocol across the WAN link 192.168.0.32/30.

Refer to the exhibit. Router R1 has an OSPF neighbor relationship with the ISP router over the 192.168.0.32 network. The 192.168.0.36 network link should serve as a backup when the OSPF link goes down.

On the second WAN link R1 is connects to the ISP router through interface S0/0/1 and IP address 192.168.0.37/30,  and the ISP router uses interface S0/0/1 and IP address 192.168.0.38/30. OSPF is running as the routing protocol across the WAN link 192.168.0.32/30.

Refer to the exhibit. Router R1 has an OSPF neighbor relationship with the ISP router over the 192.168.0.32 network.
