[j-nsp] Filtering OSPF routes

[Wayne (juniper nsp)]

MessageActually, if you are running a sufficiently high enough version of IOS (e.g. 12.0S), the 7200 can filter some LSAs.  It depends on your exact scenario if this will accomplish what you are trying to do.  It does tend to go contrary to the design of OSPF (or any link state protocol), but I suppose enough people wanted the knob, so they got it.

Not sure if JUNOS has a similar knob.

  You cannot filter OSPF. This would break the requirement that all routers have
  the same link state view.
  This is true for both Junos and IOS.
