Which statement describes the autonomous system number used in EIGRP configuration on a Cisco router?
- It carries the geographical information of the organization.
- It functions as a process ID in the operation of the router.
- It is a globally unique autonomous system number that is assigned by IANA.
- It identifies the ISP that provides the connection to network of the organization.
| Answers Explanation & Hints:
The autonomous system number used in the EIGRP configuration is not associated with the Internet Assigned Numbers Authority (IANA) globally assigned autonomous system numbers that are used by external routing protocols. It just functions as a process ID, which is necessary because a router may run multiple instances of EIGRP. Each instance of EIGRP can be configured to support and exchange routing updates for different networks. An organization has the freedom to choose its own AS number in the EIGRP configuration. |
