The IP addresses for the link from the HQ router to the ISP have alr
eady been assigned. The Serial 0/2
address of the HQ router is 209.165.200.226/27. The IP address of the Serial 0/0 of the I
SP router is
209.165.200
.227/27.

Step 2
:
Assign the subnets to the
network shown in the Topology Diagram.
When assigning the subnets, keep in mind that routing will need to occur to allow information to be sent
throughout the network.
The subnets will be a
ssign
ed to
the networks to allow for
route summarization
on
each
of the routers.
