The idea being, they are globally unique. Assume network XYZ needs to merge with network ABC. |

What happens in IPv4 when they both use the same private address space, you could be looking at re-assigning an entire 10/8 address block, including all services. It sucks. |

For IPv6, you go to the end point router for each network, configure a route to the opposite network, add some optional firewall/IPSec rules, and you're done. This saves days, if not weeks, of work with little, or no downtime. |
