Explanation:
The effects of executing this set of commands will be that Enhanced Interior Gateway Routing Protocol
(EIGRP) will be enabled in Autonomous System (AS) 44 and will be active on the router interfaces
10.0.0.2/8,192.168.5.9/24, and 10.0.5.8/16.
The router eigrp 10 command is used to enable EIGRP on a router. The network 10.0.0.0 and network
192.168.5.0 commands are used to activate EIGRP over any interfaces that fall within the major networks
10.0.0.0 and 192.168.5.0, or within any subnets of these classful networks. The network commands in EIGRP
configuration ignore any subnet-specific information by default. Since the IP address 10.0.5.8.9/24 is in a
subnet of the Class A IP network 10.0.0.0, and only the first octet (byte) of a Class A IP address represents the
major (classful) network, the remaining bytes are ignored by the network command.
EIGRP instance number 44 will not be enabled. The number 44 in the command does not represent an
instance of EIGRP; it represents an autonomous system (AS) number. The autonomous-system parameter of
the router eigrp command (router eigrp 44) specifies the autonomous system number. To ensure that all the
routers in a network can communicate with each other, you should specify the same autonomous system
number on all routers.
EIGRP will not be activated on the router interface 192.168.6.1/24. This interface does not exist within the Class
C network 192.198.5.0 or Class A network 10.0.0.0, or within any of their subnets.
