rtsold will not run on VLAN interfaces

Description

A VLAN interface for a WAN will not pull an IPv6 address via DHCPv6 with a default configuration.

In a default configuration, dhcp6c is launched via rtsold. When a VLAN-based interface is assigned, rtsold fails to run which means dhcp6c is never launched.

Running rtsold in debug mode produces the following log message:

Mar 20 12:41:41 pfsense rtsold[38666]: <make_packet> link-layer address option has null length on cpsw0_vlan10. Treat as not included.

The same message is not logged when the parent interface is used directly.

If I check "Do not wait for a RA" on the WAN settings which bypasses the need for rtsold, dhcp6c is launched directly and pulls an address.

You marked #7436 as a duplicate of this - when you check Do not wait for an RA, does your configuration yield an operational default route? I just want to understand how my issue is a duplicate of this one. Thanks.

No, there is no default gateway because rtsold won't run. DHCPv6 on its own does not handle gateways. It's the same root problem.

Ok, understood. Thanks for the explanation, I appreciate it. I'll lay low for a season and see how it goes.

Moving target to 2.4.2 as we need 2.4.1 sooner than anticipated.

Looks good now. SG-1000 with a VLAN WAN pulls an IPv6 address and default gateway now, without the "Do not wait for RA" box checked.
