Description Nir Yechiel 2017-01-18 15:29:51 UTC 
Description of problem:

In IPv6, there are couple of ways in which an IP address can be assigned, namely:

1. SLAAC (Stateless Address Autoconfiguration)
2. Stateful DHCPv6
3. Stateless DHCPv6

If a subnet is configured to use SLAAC, there is no need to use DHCP at all. The ODL ipv6service is expected to send Router Advts announcing the prefix (and default-route/MTU information) to the client.

If a subnet is configured to use stateless DHCPv6, the ipv6service router and DHCP server are going to work together: the router is going to announce the prefix, MTU and default-route, and the DHCP server is going to provide "dhcp-options" such as DNS.

If a subnet is configured to use stateful DHCPv6, the ipv6service router and DHCP server are going to work together as well: the router is going to announce default-route/MTU information, but the DHCP server is going to provide the IP address as well as any other "dhcp-options" such as DNS server.
Comment 2 Sridhar Gaddam 2017-06-30 15:35:38 UTC 
The following are the main patches in Netvirt that implement this feature.

Support Router Advertisement functionality when an RS is received - https://git.opendaylight.org/gerrit/#/c/41722/

Support Neighbor Advertisement functionality for router iface - https://git.opendaylight.org/gerrit/#/c/41821/

Support Service Binding for ipv6service - https://git.opendaylight.org/gerrit/#/c/42628/

Add a match to nd_target for IPv6 NS punt flows - https://git.opendaylight.org/gerrit/#/c/42916/

IPv6Service Binding using elanTag - https://git.opendaylight.org/gerrit/#/c/43477/

Reduce IPv6 Periodic Unsolicited RA timer interval - https://git.opendaylight.org/gerrit/#/c/44955/

Bug 7476: Configure Reachable Time in IPv6 Router Advt - https://git.opendaylight.org/gerrit/#/c/50089/
