Advertising loopbacks not as a /32

   Earl's appraoch pretty much nails it.
   
   but if ur allowed to use the loopbacks under an area ,then one thing i
   wanna add is that ( although i need to confirm reading Don Slice's
   book) if you change the loopback type to point to point,it will not be
   a candidate for router id...just treated like a regular
   interface....
   
   I was considering this my option (for not having 12.0 router id cmd)
   to manipulate which loopback gets selected as router id
   rather than the highest loopback ip...Like i said ,my routers are
   powered off for another month, so i can't confirm..Just my plan...
   
   Cheers,Padhu

   This rings a bell, I'm pretty sure 'ip ospf network point-to-point'
   does it, but like Paul just stated, I don't think that was available
   until 11.3
   
   When I had my home lab, I was running everything at 11.2(17), and I'm
   pretty sure I got it to work by changing the ospf network type to
   broadcast. (Or maybe it was non-broadcast with peer statements...)

     someone mentioned you could change the network type with certain
     ios
     versions 'ip ospf network....' Haven't tried it myself yet but look
     back a
     few days and you'll find the post.
