Hi,
We're testing dual-stack ipv4/ipv6 for clients (using SLAAC) and I'm running into an issue where the wireless client is not able to receive an IPv6 address. The vlan is configured as L2 only on the controller. The L3 interface is on the router and is configured for both ipv4 and ipv6 addresses.
I've enabled ipv6 on the target local controller. The vlan gets assigned via VSA after 802.1x authentication. The controller sees the link-local ipv6 address for clients in this vlan. The router sees the link-local address for these clients as well. The client (MacOS) is configured for "Automatic" not link-local. The router is receiving solicits on this vlan. The controller user table sees two addresses for the client MAC, an ipv4 and ipv6 link-local. Just not getting the SLAAC address.
I added ipv6 "allow all" on the validuser policy and have an allow-all ipv6 in the user role. Do I need to create a vlan interface for this vlan, or is L2 enough? There are no ipv6 interfaces configured on the controller. We are not planning to use ipv6 for AP or controller addresses at this time. I have not configured IPv6 Neighbor info or mld or anything as I assume this is more for configuring ipv6 addresses on the controller. Just looking clients on existing trunked vlans that would become dual-stacked at the router vlan interface.
Any suggestions would be appreciated!
Mike
