Why is there a delay before the other routes are added?
RIP updates are sent every 30 seconds.
Disable the debug output with either the
no debug ip routing
or the
undebug all
command.

Task 6: Determine Level 1 and Level 2 Routes
Examine the R1 routing table.
Step 1.
R1#
show ip route
<Output omitted>
Gateway of last resort is not set
172.16.0.0/24 is subnetted, 3 subnets
C 172.16.1.0 is directly connected, FastEthernet0/0
C 172.16.2.0 is directly connected, Serial0/0/0
R 172.16.3.0 [120/1] via 172.16.2.2, 00:00:11, Serial0/0/0
R 192.168.1.0/24 [120/1] via 172.16.2.2, 00:00:11, Serial0/0/0
R1#
Which of these routes are level 1 routes?
172.16.0.0/24
192.168.1.0/24
Why are these routes level 1 routes?
172.16.0.0/24 is a parent route with more specific child routes. The other is a level 1 route
because its subnet mask is equal to the classful mask.
Are any of the level 1 routes ultimate routes?
Yes, 192.168.1.0/24
Why is this route an ultimate route?
The 192.168.1.0/24 route is an ultimate route because the route contains the exit interface
Serial 0/0/0.
Are any of the level 1 routes parent routes?
Yes, 172.16.0.0/24
Why is this route a level 1 parent route?
This is a level 1 parent route because it is a level 1 route that does not contain a next-hop
IP address or exit interface for any network.
Which of the routes are level 2 routes?
172.16.1.0
172.16.2.0
172.16.3.0
