I am new to networking, and currently studying about how router learn different routes. One of my lecture slides shows the following,
First of all, please have a look at this network,
I know that
link local is created in the routing table when interface is configured, and
connected is created when an interface is active.
Now, I tried the same scenario in Packet Tracer and here is what I got when i type
show ip route command,
Router#show ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area * - candidate default, U - per-user static route, o - ODR P - periodic downloaded static route Gateway of last resort is not set C 192.168.10.0/24 is directly connected, FastEthernet0/0
My question is,
- If the interface is active why there is still two entries (
L) in routing table (in the photo), and just single
Centry in my network ?
- How come the diagram shows the ip address for link local
with subnet mask of
32because when I tried assigning ip address with
/32subnet mask to this interfacce, I got bad mask error ?
