172.116.0.0/25 because it is the first level route |
|
Router 1 is running IOS version 12.2 what will the network administrator need to do so the packets for unknown child routes of 172.16.0.0/24 be dropped? |
do nothing, IP classless is on by default |
|
With the IP classless command issued, what will router R2 do with a packet destined for host 172.16.4.234? |

A router has the following entries in its routing table: S 192.168.0.0/24 [1/0] via 192.168.128.2 O 192.168.0.0/25 [110/2175] via 172.16.1.1, 00:02:15, FastEthernet0/1 D 192.168.0.0/25 [90/22455] via 172.16.2.2, 00:12:15 Serial10/0/0 R 192.168.0.0/26 [120/2] via 172.16.3.3, 00:00:15. Seroal10/0/1 The router receives a packet that is destined for a host with the address 192.168.0.58. Which route would this router use to forward the packet? |
THE RIP route |

IP classless |
|
A packet destiend for host 128.107.0.5/16 is processed by the JAX router. After finding the static route in the routing table that matches the destination network for this packet, what does the router do next? |
Performs a recursive lookup to find the exit interface used to forward the packet |
|
|
What occurs when no IP classless is implanted on the router? |
The router will assume it has knowledge of al subnets in the network and will not search beyond child routes for a better match. |
|
|
