for more information.
3.
Determine which network resources must be shared by the
subnets. Shared resources may be connected directly to
the Layer 3 switch, if need be. Static routes to each of the
shared resources should be determined.
4.
Determine how each subnet will communicate with the
WAN or Internet. Again, static routes should be
determined and default gateways identified.
5.
Develop a security scheme. Some subnets on the network
need more security or should be isolated from the other
subnets. IP or MAC filtering can be used. Also, one or
more VLANs on the Layer 3 switch can be configured
without an IP subnet – in which case, these VLANs will
function as a layer 2 VLAN and would require an external
router to connect to the rest of the network.
6.
Develop a policy scheme. Some subnets will have a greater
need for multicasting bandwidth, for example. A policy is a
mechanism to alter the normal packet forwarding in a
network device, and can be used to intelligently allocate
bandwidth to time-critical applications such as the
integration of voice, video, and data on the network.
7.
Develop a redundancy scheme. Planning redundant links
and routes to network critical resources can save valuable
time in case of a link or device failure. The DES-3326
Spanning Tree function can be used to block the redundant
link until it is needed.
