i am reading BSCI book. i need to pass this exam after 2 weeks.
i need to understand something plz.
in this example we have a router with this configuration:

كود:
int f0/1
ip address 172.17.2.2 255.255.255.0

int s0/1
ip address 192.168.1.102 255.255.255.224
bandwidth 64

router eigrp 100
network 172.17.2.0 0.0.0.255
network 192.168.1.0
they specifies that only interfaces on the 172.17.2.0/24 subnet will participate in EIGRP. actually the network 172.17.0.0 wil be advertised beacuse EIGRP automatically summarizes routes on the major network.
my question is :
if i specify the network with wild mask 0.0.0.255 why the router will advertise the network 172.17.0.0 in class b.
