rtable, rdomain for ppp0 with DHCP assigned IP

Stuck when running cvsync in rdomain 1. It seems cvsync does not using
second routing table because of pf.conf misconfiguration or something.

em0 as a main ISP channel, ppp0 works as reserved wireless ISP channel.
Some system services like cvsync, git, ntp should use second routing
table (rtable 1) assigned to ppp0.

# route -T1 exec cvsync -c /etc/cvsync.conf
Connecting to cvsync_server_remote_IP port 7777
host cvsync_server_remote_IP port 7777: Can't assing requested address
service is not available at cvsync_server_remote_IP port 7777
