Willy's solution to use area range at the ABR before the ASBR worked; both
became OSPF IA /24 networks and redistributed into IGRP:
>If you would use an area range command on R5, then it should work:
>area 0 range 152.1.1.0 255.255.255.0
>area 0 range 152.1.2.0 255.255.255.0
Ravi's comment explains:
Your R6 (ASBR between OSPF and IGRP) routing table shows both the network as
IA entry. To summarize a IA route, you can use area range command on ABRs.
Summary address to summarize routes learned from another routing process,
and to be used on ASBRs. As your routes are IA routes, summary address will
not work.
Thanks for the help; also thanks to those who offered to recreate this
scenario on their labs.
***** This leads to one more question: ******
If we had a directly connected interface on R6 (ASBR) with a /25 mask, how
would we summarize to a /24 to get it into IGRP (static works, but for this
scenario cannot be used)? It wouldn't be an OSPF IA route, so we couldn't
use area range at the previous ABR, and summary-address doesn't work (I
tried).
