Explain what keeps IPv6 aggregation intact when there are changes upstream. For instance, what happens if your ISP changes to another upstream ISP?
What will be an ideal response?
If your ISP changes to another upstream ISP, the new ISP passes out a different 32-bit prefix. Your ISP's router, in turn, changes the 48-bit prefix it sends downstream to include the new upstream prefix. The downstream routers make an "all nodes" multicast, and the downstream clients get new IP addresses. This process keeps aggregation intact.
