Fernando Wrt to the Cisco DHCPv6 server (CNR): 1) sequential or random per configuration (can send multiple IA_NA/IA_TA if there are multiple prefixes configured for this link) 2) while client can send a 'hint' to re-use previous addresses, the server can do the same thing, we called this 'affinit

Question on DHCPv6 address assignment

2014-01-31 Thread Fernando Gont
Folks, I'm wondering about the following two aspects of different DHCPv6 implementations out there: 1) What's the pattern with which addresses are generated/assigned? Are they sequential (fc00::1, fc00::2, etc.)? Random? Something else? 2) What about their stability? Is there any intent/mechani
