I have a stub area - my office.
But I have 2 paths into it from area 0.0.0.0
Is it still a stub as its has 2 paths in and out.
so area 0.0.0.0 via rtr A to area 10.172.0.0 or area 0.0.0.0 via rtr b to area 10.172.0.0
What I want it just the DGW sent it from both rtrA and rtrB

So a stub area by default will allow LSA types 1,2, and 3; while a Totally Stubby Area is only going to allow LSA types 1,2, and the default route that you actually want. You can also create a Totally Not So Stubby Area if you have a requirement for redistribution, but it doesn't sound like you do with the information that you've provided.
Totally Stubby Areas are stub areas with an additional option bit for the vast majority of switch/routing vendors. Very few actually allow for a straight Totally-Stubby declaration. The vast majority of equipment you're simply specifying an additional parameter like no-summaries in junos or no-summary in Cisco terminology.
How you would actually get this configured is going to depend on your equipment vendor, but pretty much every vendor I've ever run across will have detailed configuration examples on how to configure Totally Stubby Areas, that's a pretty universal phrase.

I understand that you only want the default route broadcast into the area, but any reason why? Since you only have a few sites, the firewalls/routers should be able to handle a few routes. I more than twice what you have any just found it easier to set everything into area 0.0.0.0 and user weights and route distribution to send out what is needed to the far site.
Hope that makes sense.
