[c-nsp] DHCPv6

[M K]

HiYes , It's clear for me now , can you provide how to set the managed bit in the RA messages?I have configured the belowR1int f1/0ipv6 nd other-config-flag
And from R2 (the client) I can see that I can get the DNS and domain name configured in the DHCP pool
R2#sh ipv6 dhcp interface fastEthernet 1/0FastEthernet1/0 is in client mode  State is IDLE  List of known servers:    Reachable via address: FE80::C800:71FF:FE4A:1C    DUID: 00030001CA00714A0000    Preference: 0    Configuration parameters:      DNS server: 1::1      Domain name: cisco.com  Rapid-Commit: disabled

Now , I can reach this IPv6 address but the binding is not thereR1#sh ipv6 dhcp binding R1#

Even though i can also activate routing based on these addressesFrom: sjeyamurali at gmail.com
Once you enable RA on the router all IPv6 capable clients will get an IP address from the network you are advertising.

DHCP in the context of IPv6 (except for PD) is only used if you want to set the client DNS automatically, but in order for the client to go to the DHCP server you need to set the managed bit to the RA messages.

Hope this clears things a bit.
