[j-nsp] OSPF NBMA

[Harry Reynolds]

I would try adding the multipoint keyword under the interface unit, and
also add mapping for each remote dlci. The latter is needed due to lack
of inarp response (if that is still the case).

 unit 0 {
<<<<<multipoint;
      dlci 100;
      family inet {
          address 10.0.2.5/30{
	<<<<<<	multipoint-destination 10.0.2.6 dlci 100;
	 }
    }
 }

At both ends.

If I were you I'd turn on some OSPF traceoptions ... it might tell you
why it's not working
