R7---------R1--------R4
   BGP IGRP

All addressing is 172.16.x.x with /24 masks. The lab asks me to generate a
default network at R1 to be advertised to R4.

I tried putting 'ip default-network 172.16.0.0' on R1. His route table
shows the network as the candidate default.

I have tried to get that default network advertised via IGRP to R4 with no
luck ( for about 2 hours now ). Does anyone see what is missing?

R1:
router igrp 1
 network 172.16.0.0
 default-information out 5
!
ip classless
ip default-network 172.16.0.0
!
access-list 5 permit any ** also I have tried ** access-list 5 permit (all
nets beyond R1) **also I have tried** permit 172.16.0.0 0.0.0.255

R4:
router igrp 1
 network 172.16.0.0
 default-information in 5
!
ip classless
access-list 5 permit 172.16.0.0 0.0.255.255 **many variations here, too**

Thank you.
