4.2. Renumbering and Site Merging

The use of Local IPv6 addresses in a site results in making communication that uses these addresses independent of renumbering a site's provider-based global addresses.

When merging multiple sites, the addresses created with these prefixes are unlikely to need to be renumbered because all of the addresses have a high probability of being unique. Routes for each specific prefix would have to be configured to allow routing to work correctly between the formerly separate sites.
