Route summarization and IP addressing scheme ?

[cajuntank]

I have current LAN subnets that are between
10.100.1.0/24-10.100.35.0/24
I was planning on creating new subnets starting off at 10.100.0.0/29 so something like this

72.x.x.x/29--router--firewall--10.100.0.1/29--L3
|-10.100.1.x
|-10.100.2.x
|-10.100.3.x
|-etc...

What I'm looking to do is create a route summarization
for both that won't overlap. So summarization for
10.100.0.0 is easy enough at a /24 to cover all subnets created from previous statement of 10.100.0.0/29

The hard part is, can I do a route summarization of
10.100.1.0/24-10.100.35.0/24 without overlapping into my 10.100.0.0 or do I need to come up with a different addressing scheme like 10.1.1.0 instead of 10.100.0.0 ?
I'm not seeing how I can avoid not doing another scheme, but I'm not claiming to be any good at route summarizations.

You are correct in assuming that summarizing 10.100.1.0 into a supernet with any less than 24 in the mask will cross over into 10.100.0.0

I was thinking the same thing, but it was a long day and I needed a second set of eyes on this. I went ahead and changed my scheme.

Thanks.

Yeah, it took me a few as well...
