What is the gateway of last resort in the routing table of the Branch1 router?
172.20.56.1 to network 0.0.0.0
What OSPF routes are present in the routing table of the HQ router?
172.20.32.0/20 [110/782] via 172.20.56.2
172.20.48.0/21 [110/391] via 172.20.56.6
172.20.56.8/30 [110/1952] via 172.20.56.6
What is the gateway of last resort in the routing table of the HQ router?
0.0.0.0 to network 0.0.0.0
What OSPF routes are present in the routing table of the Branch2 router?
172.20.0.0/19 [110/391] via 172.20.56.5
172.20.32.0/20 [110/1172] via 172.20.56.5
172.20.56.0/30 [110/1171] via 172.20.56.5
What is the gateway of last resort in the routing table of the Branch2 router?
172.20.56.5 to network 0.0.0.0
Task 11: Reflection
On PC1, use the
tracert
command to examine the route that is used between PC1 and PC3.
What are the hops in the route to PC3?
172.20.32.1, the FastEthernet 0/0 interface of the Branch1 router
172.20.56.1, the Serial 0/0/0 interface of the HQ router
172.20.56.6, the Serial 0/0/1 interface of the Branch2 router
172.20.55.254, the IP address of PC3
Is this the least number of hops that can be used to reach PC3?
No
If the answer is
no
, why is a path with more than the minimum amount of hops used?
The serial connection between the Branch1 and HQ routers and the connection between the HQ and
Branch2 routers have a higher bandwidth than the link between the Branch1 and Branch2 routers.
Routes with higher bandwidth values have a lower calculated cost. The route with the lowest cost is
chosen as the route to the Branch2 LAN.
Task 12: Documentation
On each router, capture the following command output to a text (.txt) file and save for future reference:
show running-config
■
show ip route
■
show ip interface brief
■
show ip protocols
■
