| 1. | It is ill-advised to use BGP in certain conditions:
When the company has only one connection into the Internet When there are limited resources on the network When the user is not familiar with BGP configurations or policy-based routing
|
| 2. | BGP is classified as an External Gateway Protocol (EGP), as opposed to OSPF, EIGRP, RIP, and so on, which are known as Interior Gateway Protocols (IGP). BGP can send a summary of the networks known within an organization to maximize security and minimize bandwidth overhead. It is used to convey routing information between autonomous systems. |
| 3. | The easiest way to connect to the Internet is to take default routes from all providers. This provides your company with a backup path if one provider fails. Because you are only receiving one route, the processor and memory utilization is quite low. |
| 4. | Before iBGP can propagate a route, the route must be known from another source. |
| 5. | Idle, Connect, Open Sent, Open Confirm, Established. |
| 6. | Answer:
Neighbor BGP Table Routing Table
|
| 7. | The established state should display if the neighbor relationship is working correctly. |
| 8. | Load sharing. |
| 9. | For the majority of autonomous systems, synchronization is disabled—most autonomous systems are not transit autonomous systems. |
| 10. | Several answers are possible: path vector, exterior gateway protocol, interdomain routing protocol. |
