Hi Carlos,
No ip subnet-zero is enabled on all routers in the IGRP domain.
As mentioned the debug ip igrp transactions still shows that the 'edge' router
is not advertising the 172.16.0.0 address so its simply not redistributing it,
but even when I no passive the 172.16.0.1 interface it still won't advertise it
:(
The interface is definately up and I can ping across it so there's no reason
except for some weird IGRP issue.
As a not i changed it to another subnet /24 of the range and it does work so it
is something specific to the .0 subnet and yet ip subnet-zero and ip classless
are applied.... weird
I've tried rebooting, redistribute connected, redistribute from another protoco
l
and even simply including it in the IGRP domain but nothing works, IGRP only
advertises subnets and not the .0/24 subnet :(
