Refer to the exhibit. The network consists of hundreds of routers branched from connected regional distribution sites using single area OSPF. Recent network failures caused packet flooding and route recalculations in all branch networks. What should the engineer do to minimize the effect of the routing instabilities? |

Definition
| Change the topology to a heirarchical design which puts each branch network in its own area. |

| 6. The command ip route 192.168.2.0 255.255.255.0 172.16.2.2 was entered into the router. After network changes were made, the new next hop for the 192.168.2.0/24 network is 172.16.5.1. What should an administrator do so that the router will use the new next hop to reach the 192.168.2.0 network? |
|
Definition
| Enter the command clear ip route |

| 0. What is the purpose of the TTL field within an IP packet header? |
|
Definition
| limits the period of time or number of hops a packet can traverse through the network before it should be discarded |
