Hi team,
It's been a while since I've posted a question, still following the list but
life took over my CCIE studies but now I'm back into it. Question regarding
NSSA Type7 to Type 5 Suppression. Cisco doco suggest that you can do this by
using the no-advertise command on the summary-address statement under OSPF on
the ABR. My question is whether we can also do this using the area-filter
command?
I've labbed quickly and it sort of works, but only if I've got an additional
network in my NSSA that I want to filter. My environment is backbone conected
to a totally NSSA area. I want to inject an external route into the NSSA but
not have this advertised into the backbone. I'm just thinking from a
scalability point of view, if I have a lot of external routes I dont want to be
using multiple summary statements.
Thanks
Bal
