Each subnet has 62 IP addresses for host addressing. Based on the preceding IP ad-
dressing scheme, Pearland Hospital does not need networks 200.100.4.0/24 through
200.100.10.0/24.
9.
Recommend routing protocols that support variable-length subnet masks (VLSM).
The network is small. Recommend Enhanced Interior Gateway Routing Protocol
(EIGRP). Do not recommend OSPF because of its configuration complexity.
10. Recommend using 1 wireless LAN controller (WLC) and two wireless access points
(AP) on each floor for redundancy. Use a VLAN that spans floors 6 through 10.
Change the router to a Layer 3 switch. Use the router for WAN access.
11. Figure 16-2 shows the diagram. The router is replaced by the L3 switch with 10 Giga-
bit Ethernet to provide high-speed switching between LANs. Dual links are used to
provide redundancy between the access layer and the core/distribution layer. Each
floor has an IP subnet plus a subnet for the WLAN and another for the data center.
Each floor has two access points for redundancy and access switches with 10 Gigabit
Ethernet Uplinks to the data center. Servers can connect using Gigabit Ethernet.
