Section: Addressing and Routing Protocols in an Existing Network Explanation Explanation:
Of the choices available, packets sent to 192.168.0.17 and 192.168.0.26 will be forwarded to the 10.1.1.3 next-hop IP address. When a packet is sent to a router, the router checks the routing table to see if the next-hop address for the destination network is known. The routing table can be filled dynamically by a routing protocol, or you can configure the routing table manually by issuing the ip route command to add static routes. The ip route command consists of the syntax ip route net-address mask next-hop, where net- address is the network address of the destination network, mask is the subnet mask of the destination network, and next-hop is the IP address of a neighboring router that can reach the destination network.
A default route is used to send packets that are destined for a location that is not listed elsewhere in the routing table. For example, the ip route 0.0.0.0 0.0.0.0 10.1.1.1command specifies that packets destined for addresses not otherwise specified in the routing table are sent to the default next-hop address of
10.1.1.1. A net-address and mask combination of 0.0.0.0 0.0.0.0 specifies any packet destined for any network.
If multiple static routes to a destination are known, the most specific route is used? the most specific route is the route with the longest network mask. For example, a route to 192.168.0.0/28 would be used before a route to 192.168.0.0/24. Therefore, the following rules apply on RouterA:
Packets sent to the 192.168.0.0 255.255.255.240 network are forwarded to the next-hop address of

10.1.1.4. This includes destination addresses from 192.168.0.0 through 192.168.0.15.
Packets sent to the 192.168.0.0 255.255.255.0 network, except those sent to the

192.168.0.0255.255.255.240 network, are forwarded to the next-hop address of 10.1.1.3. This includes destination addresses from 192.168.0.16 to 192.168.0.255.
Packets sent to the 192.168.0.0 255.255.0.0 network, except those sent to the

192.168.0.0255.255.255.0 network, are forwarded to the next-hop address of 10.1.1.2. This includes destination addresses from 192.168.1.0 through 192.168.255.255.
Packets sent to any destination not listed in the routing table are forwarded to the default static route

next-hop address of 10.1.1.1.
The 192.168.0.17 and 192.168.0.26 addresses are within the range of addresses from 192.168.0.16 to
192.168.0.255. Therefore, packets sent to these addresses are forwarded to the next-hop address of
10.1.1.3.
The 192.168.0.1 and 192.168.0.14 addresses are within the range of addresses from 192.168.0.0 through
192.168.0.15. Therefore, packets sent to these addresses are forwarded to the next-hop address of
10.1.1.4.
The 192.168.1.1 IP address is within the range of addresses from 192.168.1.0 through 192.168.255.255.
Therefore, packets sent to 192.168.1.1 are forwarded to the next-hop address of 10.1.1.2.
RouterA does not have a specific static route to the 172.16.0.1 network. Therefore, packets sent to
172.16.0.1 are forwarded to the default static route v address of 10.1.1.1.
