     According to Bruce Caslow (speaking to him in person), there isn't
     any way for OSPF to summarize out of the OSPF domain. You may
     summarize into OSPF at the ASBR(summary) or summarize out of an
     area at the ABR(area range). The other way to get this IGRP
     network functioning would be to specify an IP DEFAULT-NETWORK on
     the router that contains both IGRP and OSPF. Make sure to specify
     a wholly unique major network number that does not exist within the
     IGRP domain.
     
     I know i've heard many people say that summary out of OSPF works,
     and to admit it I haven't tested it. Please feel free to comment.

     You need to summarize the 30-bit and 28-bit subnets to a 24-bit
     subnet with
     a
     static route. Check the case study on P.730 of Doyle's Routing
     TCP/IP. That
     may help.

     Subject: OSPF Routing
     Hey Gang!
     Question:
     I have a frame backbone running OSPF Area 0. Two of the spokes are
     connected via ISDN as well. (Address spaces vary from /24, /30,
     /28, etc
     for 140.100.0.0 address.)
     The hub router is also connected to an IGRP domain (/24 for
     140.100.0.0).
     The problem I am having is that I can't seem to get the ISDN link
     140.100.5.0/30 advertised to the IGRP domain. The ISDN link is in
     AREA 0. I
     believe that if the link was in another area (ie 3), I could use
     the well
     known, area 3 range... cmd).
     What do I do, since it is in Area 0 and is connected to the ASBR?
     Any ideas?
     Thanks,
     Ben
