Mi Markus,
        Yes, this is normal. IGRP does not understand the concept of 0.0.0.0/0
as a
default route. You need to use the ip default-network command to allow IGRP
to announce this route as the default to them. EIGRP does not have this
problem as evidenced by what you found.
HTH,

Subject: External default-route not propagated into IGRP within the same
ASN

Hi,

I configured redistribution between EIGRP and IGRP in
the same AS.
I redistribute from OSPF the default-route into EIGRP.
The EIGRP process see the default-route marked with "*D EX .....".
On one router within my EIGRP domain I configured both
routing prcesses:

R1--<OSPF>--R2--<EIGRP 1>--R3--<IGRP 1>--R4

The default-information will not be automaticly (like the
other subnets) propagated to the IGRP domain (R4 don't see
a default-route).
When I don't use the default-informaton (learned from OSPF)
within my EIGRP domain and configure instead of
a "ip default-network", so that the default-route will be appears
in the FIB with "*D ..." the information will be propagated to
IGRP automaticly.

Is this a normal issue and how can I solve this issue ?

Markus
