What does the routing table for rdomain 2 look like (route -T2 -n show)? Does
it have a default route? To set routes pushed from the server in that rdomain,
you might need to use up/down scripts on the client (commented lines at the
bottom of your pia.ovpn).
I'm using a very similar config:
$ cat /etc/hostname.tun0
up
rdomain 1
!/usr/local/sbin/openvpn --daemon --config /etc/openvpn/config.ovpn
$ ifconfig tun0
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> rdomain 1 mtu 1500
index 13 priority 0 llprio 3
groups: tun
status: active
inet 10.8.8.9 --> 10.8.8.1 netmask 0xffffff00
$ route -T1 -n show
