hello,
I tried the 2nd OSPF process solution for the OSPF to IGRP mask problem,
and it works fine until I try to remove the OSPF-generated static summary
to Null0 with 'no discard-route external'.
With the Null0 summary gone from r1's routing table, it also stopped
advertising the /24 summary into IGRP (r2).
Is that the correct behaviour? If so, then this solution would not work
if OSPF-generated static summaries to Null0 are not allowed...
Thanks in advance for any help :)
r2 [12.1(5)T5]
|
| IGRP 135.4.56.0 /24
|
r1 [12.2(1)]
|
| OSPF 135.4.34.0 /29
