yes, ospfv3 is running on both tlp4 and gre0, and tcpdump shows HELLO
packets going out both.  on tlp4 each ospf router answers ff02::5
pings, while on gre0 none answer.

Maybe this is related:

May 15 02:35:43 ezln ospf6d[748]: Network: Join AllSPFRouters on ifindex 16 failed: Operation not permitted

'show ipv6 ospf6 int' confirms ifindex 16 is the gre0 interface.

You're right, the behavior is the same.  I get the same syslog error
message, the same ping6 behavior, the same ifmcstat output.
