Oliver, just as an aside.. whats the benefit of having these in the OSPF rather 
than redistributed.. I guess my concern is for example on each PoP I assign /30 
customer connections out of /24 blocks so I could easily add the /24 as on ospf 
network, however it means I must remember to set each interface passive 
explicitly and I'm worried I'll forget and I dont want my customers to get my 
ospf traffic...
