Determining the Static Routing Needs
Not counting the WAN link to ISP and the Web Server LAN, how many total networks are there in the
topology? (Hint: Don't forget the WAN links between HQ and B1 and B2.)
12 networks
What networks does HQ
not
have listed in its routing table?
All the LAN networks attached to B1 and B2—a total of eight networks.
Assuming that you will not summarize these networks, how many static routes need to be configured
on HQ?
8
What networks does B1
not
have listed in its routing table?
All the LAN networks attached to HQ and B2 as well as the WAN link between HQ and B2—a total
of seven networks.
Assuming that you will not summarize these networks, how many static routes need to be configured
on B1?
7
What networks does B2
not
have listed in its routing table?
All the LAN networks attached to HQ and B1 as well as the WAN link between HQ and B1—a total
of seven networks.
Assuming that you will not summarize these networks, how many static routes need to be configured
on B2?
7
List the Static Route Commands
For each router, record the static route commands you would use to configure the static routes with
the next-hop IP address specified.
Static routes with the next-hop address for HQ:
