FreeBSD as multicast router

Hi All
Still trying to run FreeBSD-box as multicast router :-)
FreeBSD upgraded to 11.3-STABLE #1 r354778. netstat pacth by Mike Karels
manually applied and netstat -gs looks OK now.
Latest pimd version 3.0beta1 downloaded from git and configured. While
configure it report following:
=====
------------------ Summary ------------------
pimd version 3.0-beta1
Prefix................: /usr/local
Sysconfdir............: /usr/local/etc
Localstatedir.........: /usr/local/var
C Compiler............: cc -g -O2
Optional features:
Kernel register encap.: no
Kernel (*,G) support..: no
Kernel MAX VIFs.......: 32
Memory save...........: no
RSRR (experimental)...: no
Exit on error.........: yes
=====
What does "Kernel (*,G) support..: no" means?
Then my test multicast network configured (again)
-------------------- ----------
-vlan298-| FreeBSD PIM router |-vlan299-| client |
|208.34/29 205.2/29| |205.5/29|
-------------------- ----------
Two multicast generated by FreeBSD-router: one (232.232.9.43) sended
from vlan299 and another (232.232.88.173) from vlan298 both with TTL=20
Pimd started with following config:
=====
phyint vlan299 enable ttl-threshold 20
phyint vlan298 enable ttl-threshold 20
rp-address 10.200.205.2 232.232.0.0/16
=====
Now client is requesting multicast which router is sending from vlan299
and client successfully receiving it. But when client is requests
multicast sending (by router) from vlan298 it doesn't receive it.
My first question: (in theory) is router must send multicast to client
in this situation?
And the second: why :Ttls is 1 at `netstat -f inet -g` output:
=====

=====
Any suggestion?
