R1:

Now R1 fails:

freevrrpd[86670]: restoring real MAC address: 00:00:E8:41:CD:10 for interface vlan0
R2 works as a master now:

% ifconfig vlan0
vlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

ether 00:00:5e:00:01:01
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
vlan: 1 parent interface: xl0
R1 can probe R2 (using other interface and address):
% ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1): 56 data bytes
64 bytes from 192.168.1.1: icmp_seq=0 ttl=64 time=0.356 ms
64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=0.306 ms
64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=0.265 ms
^C
--- 192.168.1.1 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max/stddev = 0.265/0.309/0.356/0.037 ms
However, I have no more computers on this vlan and I can't
touch other vlans right now.
cheers,
