❑ The introduction of a router into your network could create
security issues from unauthorized access to your network.
❑ A VLAN that spans several stacks of switches will require a port on
each switch for the interconnection of the various parts of the
VLAN. For example, a VLAN that spans three switches would
require one port on each switch to interconnect the various
sections of the VLAN. In network configurations where there are
many individual VLANs that span switches, many ports can end up
being used ineffectively just to interconnect the various VLANs.
