Static Routes Configuration

R1 can ping R2 because the destination IP address 172.16.2.2 is directly connected through the Serial0/1/0 interface. However, R1 cannot ping the R3 LAN at 192.168.2.1 because there is no route in the routing table for the 192.168.2.0/24 network. The routing table only shows entries for directly connected networks and associated local addresses.

The 'Gateway of last resort is not set' message indicates that there is no default route configured on the router. This means that if the router does not have a specific route for a destination, it will not know how to forward the traffic.

R1 has entries for 172.16.2.0/24 and 172.16.3.0/24 in its routing table because these networks are directly connected to R1. The router has interfaces in these networks, which is why it has entries for them in its routing table.

<p>The 0 percent success rate when pinging 192.168.2.1 indicates that there is no route to the 192.168.2.0/24 network. This could be due to the absence of a route for that network in the routing table, leading to the failure of the ping requests.</p> Signup and view all the answers

<p>A fully specified static route includes both the exit interface and the next-hop IP address, while a default static route matches all packets and has a network address of 0.0.0.0 and a subnet mask of 0.0.0.0.</p> Signup and view all the answers
