What can be determined from this output?
• The router will have to perform recursive lookups to forward a packet destined for 192
...
2
...

• The parent route for these networks was removed from the routing table
...
168
...
0/25 would be classified as a supernet route for the routes listed in the routing table

A packet destined for host 128
...
0
...
After
finding the static route in the routing table that matches the destination network for this packet, what does
the router do next?
• searches for a default route to forward the packet
• drops the packet since the static route does not have an exit interface
• performs a recursive lookup to find the exit interface used to forward the packet
• sends a request to neighboring routers for the location of the 128

Which route
would this router use to forward the packet?
• router use to forward the packet?
• the static route
• the OSPF route

• A classless routing protocol has been configured on the router
...

• Multiple routes with different masks to the same destination are in the routing table
...

...

• The router will only support classful routing protocols
...

• The router will assume it has knowledge of all subnets in the network and will not search beyond child
• routes for a better match
