346 Part Three • IPv6 Practice
• If IPv6 is handled in software, what device image is required
for IPv6 support?
• Are there additional hardware requirements to support IPv6—
or the new software image—like additional memory or
storage?
• If this is a multivendor network, carefully compare the compo-
nents for hardware support capabilities (i.e., one vendor may
support gigabit Ethernet for IPv6, whereas another vendor will
not).
• Verify that the routing scheme used on the network will sup-
port IPv6. Verify that the layer 3 switches in the network
support IPv6.
• Layer 2 switches, since they do not examine or act upon IP
headers, should support IPv6 without ...
