So the routers on NMS running the oldest RouterOS (6.0) are:
On WMS (which includes more routers not running OSPF) there are a couple of routers still running 5.x?
# lastip, osver
172.18.52.14, 5.24 - rb1.neocities.ctwug.za.net
172.18.214.249, 5.16 - ???
172.18.169.77, 5.23 - rb2.simba.ctwug.za.net.
172.18.172.181, 5.26 - ???
Maye we can get these upgraded. If someone can contact the node owners?
