SVIs. Because all traffic has been migrated, these rates should be low after this is<br />

confirmed. The SVIs on Denmark <strong>and</strong> Scotl<strong>and</strong> can be shut down, as shown in Example 14-<br />

46.<br />

A similar process is done with the uplinks on Denmark <strong>and</strong> Scotl<strong>and</strong>. Routing protocol<br />

hell<strong>os</strong> should be the only traffic on these links <strong>and</strong> can be shut down, as shown in Example<br />

14-47.<br />

Example 14-47. Routed Uplinks Are Shut Down on Denmark <strong>and</strong> Scotl<strong>and</strong><br />

denmark(config)# interface range port-channel2-3<br />

denmark(config-if)# shutdown<br />

Design Note<br />

When the routed uplinks are down, the 6500 loopback addresses that were previously<br />

used to manage the devices are unreachable. A single SVI in one of the existing (or a<br />

new) VLANs is created <strong>and</strong> used to manage the devices moving forward.<br />

The migration of Denmark <strong>and</strong> Scotl<strong>and</strong> is now complete, as shown in Figure 14-4.
