Lab 6 Route Summarization for discontinuous IP addresses

Topology

Basic Setting
As Topology

IPs for routers and PCS have been configured.
Static routes for Sect A have been configured, and every segments in A can work properly.

Static route between B and A has been configured.
Sect C with a segment of 172.16.6.0/24 was added in this network.

In Router 4, the route for 172.16.0.0/21 was via 192.168.1.1，but now ,a segment of 172.16.6.0/24, and this segment is actually part of 172.16.0.0/21.
Therefore, you need to configure a route to 172.16.6.0/24.

Requirements
You need to add a route to 172.16.0.0 255.255.248.0 on router 4.
On router 2,3,0 and 1, you need to add routes to 172.16.6.0/24.

Steps
On Router8
Summarize 192.168.0.0/24 and 192.168.1.0/24 to 1 segment
Router(config)#ip route 192.168.0.0 255.255.254.0 192.168.2.1
Router(config)#ip route 172.16.0.0 255.255.248.0 192.168.2.1

On Router4
Router(config)#ip route 172.16.6.0 255.255.255.0 192.168.2.2
Router(config)#^Z
Router#show ip route
172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks
S 172.16.0.0/21 [1/0] via 192.168.1.1
S 172.16.6.0/24 [1/0] via 192.168.2.2
C 192.168.0.0/24 is directly connected, FastEthernet0/0
C 192.168.1.0/24 is directly connected, Serial2/0
C 192.168.2.0/24 is directly connected, Serial3/0

On Router2
Router(config)#ip route 172.16.6.0 255.255.255.0 192.168.1.2

On Router3
Router(config)#ip route 172.16.6.0 255.255.255.0 172.16.4.2

On Router0
Router(config)#ip route 172.16.6.0 255.255.255.0 172.16.3.1

On Router1
Router(config)#ip route 172.16.6.0 255.255.255.0 172.16.5.1
